AnyRep Development Brief: Exercise Animations, Calorie Tracking, Progress Dashboard and Custom Challenges Request for quote, issued to prospective app development partners 1. About this brief AnyRep (“AnyRep: Workout Anywhere”) is a live iOS and Android fitness app, published by Might Just Work, that lets a user point their phone at a room, whether that is a gym, a lounge room or a hotel room, and generates a workout plan from the equipment and space it detects. We are seeking quotes from app development partners to add four features to the existing app for launch. We have deliberately kept the initial scope focused, with further enhancements to follow post-launch based on user feedback. This document sets out the scope, the assets we will provide, and what we need included in your quote so that responses are easy to compare side by side. 2. Scope of work 2.1 Incorporate exercise animations We are considering purchasing the Classic tier of the RepDB exercise dataset ([login to view URL]). We would like this to be integrated into the existing AnyRep exercise screens so that, wherever a match exists, an exercise in a generated workout displays its corresponding animation and exercise data. Asset and data specification (RepDB Classic, Standard tier): • Static images: transparent-background WebP, 1024 x 1024, one classic-style 3D-rendered illustration per exercise with muscle highlighting • Animations: transparent-background looping WebP animations showing the full rep in motion, roughly 960px • Structured data: JSON and SQLite database of exercise names, muscle groups and equipment, available in English, German and Spanish • Licence: one-off commercial purchase, no ongoing subscription or per-download fees Because AnyRep's AI-generated workouts can call on an effectively unlimited range of exercises (for example, unusual variations like keg deadlifts), we expect there will not be a matching animation for every possible exercise. At this stage, we are using a clean text-only exercise card where no match exists, rather than treating this as a blocking issue. We would like your view on: • How you would match AnyRep's existing exercise list against the RepDB dataset, and how you would handle exercises with no match • The expected impact on app download size and, if relevant, whether animations could be bundled on-demand or lazily downloaded rather than shipped in the initial install, so users are not forced into a large download over mobile data • Roughly how much time you expect this integration to take, as this is the item we are most keen to understand feasibility and effort for 2.2 Add calorie burn estimation Add fields for weight, gender and age to the user profile (with sensible defaults or an option to skip), and use these to estimate calorie burn per workout and display it to the user. 2.3 Expand the progress tab Under the existing progress tab, add tracking and charts for: • Steps • Calories burned • Number of workouts completed • Weight progress • Muscle fatigue We like the general presentation approach used by the GymVision app for this kind of progress dashboard and are happy to discuss as a reference point, though the final design should fit AnyRep's own style. 2.4 Build yourself a challenge Add a feature allowing users to create their own custom challenge, for example a self-selected duration such as 30 days, built around a goal they choose (for example, lose fat, build muscle, or increase stamina). This is intended as a key driver of repeat use and return visits to the app, so the experience should feel motivating and easy to set up, rather than a heavy configuration screen. • Users choose a duration and a goal, and the app assembles or adapts a program to match • Progress against an active challenge should be visible and trackable (days completed, current streak, days remaining) • We are open to your recommended technical approach, including whether challenge logic runs entirely in-app or is served from a lightweight backend, please include your reasoning in your quote 3. What we will provide • Access to the existing AnyRep codebase and repository, including the handover documentation from our current developer • The purchased RepDB Classic dataset and animation library, once confirmed • Current exercise data and taxonomy used by the app • Brand and UI style guidance for AnyRep • A point of contact for product questions during the build 4. What we need in your quote 1. Company overview and relevant experience, including any past work integrating illustrated or animated exercise content, health/calorie calculations, analytics dashboards, or habit and challenge-style features 2. Your recommended technical approach for each of the four scope items in section 2, including your approach to exercise matching and fallback for 2.1, and bundled versus backend-served content for 2.4 3. A fixed-price quote, broken down by each of the four scope items in section 2, rather than a single lump sum or an open-ended hourly estimate 4. For item 2.1 specifically, your estimate of effort and elapsed time, and any impact on app size and download experience 5. Estimated timeline from contract signature to a release-ready build, including key milestones 6. Your proposed payment structure (we expect milestone-based payment rather than full payment upfront) 7. Two or three references or portfolio examples relevant to fitness apps, animation/illustration integration, or progress-tracking and challenge features 8. Confirmation of which platforms you will deliver for (iOS, Android, or both) and the languages/frameworks involved 9. Any assumptions, exclusions or risks you want to flag before work begins 5. Timeline for this process Please submit your quote in writing, addressing each item in section 4. We are sending this brief to a small number of development partners in parallel and will review all quotes together before selecting a partner. If anything in this brief is unclear, please raise it with us before submitting your quote rather than making assumptions, we are happy to clarify scope on a short call.

A Warm Hello! We are readily available to start working on this project! We understand that AnyRep is already a live iOS and Android application, and the objective is to add four focused features without disrupting the existing workout-generation experience. Our approach would therefore prioritize integration with the existing codebase, backward compatibility, performance, clean UX, and a release-ready implementation rather than unnecessarily rebuilding existing functionality. We are a full-stack mobile development agency experienced in fitness applications, API integrations, animated/visual content, analytics dashboards, health-related calculations, user progress tracking, and engagement/challenge features. We are available to begin promptly and would be happy to review the existing AnyRep repository, current exercise taxonomy, and RepDB dataset to finalize the fixed-price scope and implementation plan. Best regards, Ana

Hi there, I bring 20+ years of software experience and 12+ years building production mobile apps for iOS and Android, with Flutter as my primary cross-platform framework. I can extend AnyRep while respecting its existing architecture, visual language, and AI-generated exercise workflow. For RepDB, I would normalize names, equipment, muscles, and aliases into a maintainable matching layer, use confidence-based matching with manual overrides, and keep unmatched exercises on the current text-only card. I would assess asset size early and prefer lazy or on-demand media loading where practical, avoiding an unnecessarily large initial install. I would add optional profile inputs and transparent calorie estimates, then build a focused progress dashboard for steps, calories, workouts, weight, and fatigue with efficient aggregation and clear charts. Custom challenges should remain simple for users: duration and goal create an active program with streak, completion, and remaining-day tracking. I would keep the first version in-app unless cross-device synchronization or server-managed adaptation requires a lightweight API. I will begin with a codebase review and data audit, then provide a clear milestone plan, tested iOS and Android builds, source code, and documentation. I would be glad to discuss the existing stack and RepDB data in detail.

Hi — Elias here from Miami. I’ve reviewed the four requested additions. Since AnyRep is already live, my first step would be auditing the existing iOS/Android architecture and exercise taxonomy so these features extend the current product cleanly rather than creating parallel systems. The most interesting technical piece is RepDB matching. I’d build a normalized mapping layer using exercise names, aliases, equipment and muscle groups, with an explicit fallback to your existing text card when confidence is insufficient. I would avoid bundling the full animation library if it materially increases install size; CDN/object-storage delivery with local caching is likely the better approach. I’ve worked on mobile apps involving structured content, media delivery, analytics/progress dashboards, AI-driven workflows, and persistent user state. A few questions before preparing the fixed module-by-module quote: Q1 – What framework/native stack is the current app built with? Q2 – Are steps currently sourced from Apple Health/Health Connect? Q3 – Does AnyRep already have a backend storing workout/progress history? Looking forward to hearing from you.

Hey there, For AnyRep, I’d treat the RepDB integration as the first feasibility checkpoint. The key issue isn’t displaying the animations, but matching RepDB’s taxonomy against AnyRep’s generated exercise names while keeping unmatched variations as the existing text-only cards. I’d also avoid forcing the full animation library into the initial install if its size makes the download experience noticeably heavier. For the challenge feature, I would keep setup deliberately lightweight, duration + goal first, with the generated/adapted program and progress tracking doing the complexity behind the scenes. I can work across the existing iOS/Android codebase, but the brief doesn’t provide my framework, relevant portfolio examples, fixed pricing, or timeline, so I won’t invent those details. If you share the current tech stack and approximate exercise count, I can scope the integration more accurately. Best regards, Hammad Hassan

Hi, I noticed that making exercise animations and adding progress tracking are key needs for your app. I’ve worked on fitness apps with animated exercises and tracking features before. I’ll handle matching exercises with RepDB data, and I can suggest lazy loading animations to keep install size small. Do you want the challenges to sync in real-time or run locally? Let’s chat more to plan a bigger, better version together. Regards, Nick.

@zainalitariq245

Hi, I understand anyRep already has the core workout engine, so the main challenge is adding these features without creating friction or weakening the existing experience. The biggest risks I see are reliably matching AI generated exercises with RepDB, controlling animation size and loading, and designing progress and challenge logic that remains simple for users. I would first review the existing codebase, exercise taxonomy, data flow, and current progress architecture. For RepDB, I would build a normalized matching layer with clear fallback rules for unmatched exercises, then use lazy loading where practical to keep the initial app size reasonable. Calorie estimates, progress metrics, and custom challenges would be integrated into the existing architecture rather than built as isolated features. I can deliver both iOS and Android and provide milestone based development with testing and release support. Which framework is the current AnyRep app built with, and can you share the repository structure before we finalize the estimate?? Let’s turn your project into measurable results. My portfolios, https://www.freelancer.pk/u/zainalitariq245 Looking forward to discussing your project further. Best Regards, Zain A.

Hi there, Hope you are doing well I’d love to help enhance AnyRep: Workout Anywhere with the requested fitness, progress-tracking, animation, and challenge features. We have experience building scalable mobile applications with workout modules, analytics, API integrations, user profiles, and engaging fitness-focused experiences. 1. Exercise Animations & RepDB Integration Match AnyRep exercises with RepDB using normalized exercise names, equipment, muscle groups, and aliases. Create a mapping layer so existing exercises can connect to RepDB content without changing the core workout engine. Display animations wherever a match exists and retain the existing text-only card as a fallback. We can evaluate lazy/on-demand asset delivery versus bundling to keep the initial app size reasonable. 2. Calorie Burn Estimation Add weight, gender, and age to the profile with optional onboarding. Implement a reliable calorie estimation model based on workout duration, exercise intensity, user characteristics, and available workout data. Display estimated calories per workout and make the architecture flexible for future improvements. 3. Progress Dashboard We’ll expand the existing Progress section with clean charts and summaries for: Steps Calories burned Completed workouts Weight progression Muscle fatigue Thanks & Regards Dheeraj K.

@webnautical

Hello! As per my understanding you need four production-ready features added to the existing AnyRep mobile application for both iOS and Android. RepDB exercises need reliable matching against AnyRep’s AI-generated exercise taxonomy, with graceful text-only fallback when no confident match exists. Calorie estimation should use profile data and workout intensity/duration, while the Progress tab needs clear charts for steps, calories, workouts, weight, and muscle fatigue. Custom Challenges should let users quickly choose a goal and duration, receive an appropriate program, and track streaks, completed days, and remaining progress. I will integrate these features into the existing architecture, preserve AnyRep’s visual language, test both platforms, and deliver a release-ready build with documented changes. Queries: What framework and backend are currently used by AnyRep? Approximately how many exercise names currently exist in AnyRep’s taxonomy? Does the current backend already store workout history, weight, and user progress? I am looking forward to working on this project with you! Best Regards, Ravi

@temoberishvili

Hello! This is Temo. I see you're looking to enhance your fitness app with features like exercise animations, calorie tracking, and a progress dashboard. Those additions can significantly boost user engagement and retention. With around 10 years of experience in mobile app development, I've handled similar projects that prioritize user experience and functionality. I understand your main goal is to create a comprehensive tool that motivates users through tracking and custom challenges. To achieve this, I suggest breaking the development into phases: first, we can focus on designing and implementing the exercise animations, then integrate the calorie tracking system, followed by building the dashboard for visual progress representation. Some similar things I've built include a fitness tracking app, a local marketplace app, and a custom dashboard for a health service. Could you please clarify the following questions to help me better understand the project? Q1: What specific animations or styles are you envisioning for the exercise demonstrations? Q2: How do you plan to manage and update the calorie data for different exercises? Q3: Are there any specific metrics you want to highlight on the progress dashboard?

@Eliteinno

The RepDB integration is the part I’d scope first, because AnyRep can generate exercises that won’t have a direct dataset match and the animations could materially affect app size. I’d build a normalized exercise-matching layer with a text-only fallback, then lazy-load matching WebP assets where practical rather than forcing the full library into the initial install. The calorie estimates, progress charts, and custom challenges can then use the existing user/workout data model rather than creating parallel tracking systems. Is AnyRep’s current exercise catalog already stored locally, remotely, or generated entirely at runtime?

Hello! As per your project post, you are looking to enhance AnyRep your existing iOS and Android fitness application that uses AI and camera based analysis to generate workouts based on available equipment and space. The immediate goal is to add exercise animations, calorie burn estimation, an expanded progress dashboard, and customizable challenges while keeping the experience focused and motivating for users. My focus will be on extending the existing application with RepDB exercise animation integration, intelligent matching between your current exercise taxonomy and the RepDB dataset, fallback handling for exercises without matching animations, and an efficient approach to managing animation assets without unnecessarily increasing the initial app download size. I specialize in cross platform mobile development, fitness applications, API and data integrations, analytics dashboards, user engagement features, and scalable application architecture. I will work directly with your existing codebase and documentation so the new functionality integrates cleanly with the current AnyRep experience rather than creating disconnected modules. Let’s connect to review the existing AnyRep architecture, RepDB dataset, and current exercise workflow so we can define the most efficient approach for these four launch features and ensure they integrate smoothly with the existing application. Best regards, Nikita Gupta

@HamparProd

Hi, The important part here is adding these four features without destabilising the existing AnyRep experience or unnecessarily increasing the app download size. I would start by reviewing the current codebase and exercise taxonomy, then map AnyRep exercises against RepDB using normalized names, aliases, equipment and muscle metadata rather than relying on exact-name matching. Unmatched exercises would retain the existing text card, while animations can be cached/lazy-loaded where the current architecture allows it. I have experience extending production mobile applications where existing data models, user progress and release stability need to be preserved. For calorie tracking and progress, I would keep calculations deterministic and testable. The dashboard would extend the existing Progress experience, while custom challenges would reuse the current workout-generation logic where practical rather than creating a second competing system. I would deliver both iOS and Android, including integration testing and release-ready builds. Fixed price: AUD $3,200 Timeline: 5 weeks I can start with a codebase review after award and confirm the RepDB mapping/download strategy before implementation begins.
