Looking for an iOS Developer to Build a Subscription-Based Productivity/Fitness App (iPhone Only) Description I am looking for an experienced iOS developer to build an app similar to PushUp Time, but for iPhone/iOS only. The concept of the app: users select distracting apps such as Instagram, TikTok, YouTube, or X. When they try to open one of these blocked apps, they must first complete a physical exercise such as push-ups, squats, or sit-ups. The app should automatically count repetitions using the camera and pose detection. Once the goal is completed, the user gets temporary access to the selected app(s). The app should have a subscription-based business model. Monetization should be fully focused on premium subscriptions, such as: • monthly subscription • yearly subscription • optional free trial or limited free version Required Features • iPhone app only • block selected distracting apps • camera-based exercise detection with rep counting • exercises: push-ups, squats, sit-ups • configurable unlock duration • option to unlock one app or multiple apps at once • onboarding flow • premium paywall • subscriptions through Apple In-App Purchases / StoreKit • analytics / progress tracking • settings for difficulty level and number of reps • clean, modern, and simple UI/UX • privacy-friendly processing, preferably as much as possible on-device Technical Preferences • Swift / SwiftUI • experience with iOS subscriptions / StoreKit • experience with camera / pose detection / Core ML / Vision • clean and scalable code • preferably someone who can also think along on UX and App Store launch Goal The purpose of the app is to help users reduce scrolling and become more productive by linking screen time to physical movement. The revenue model should be based on recurring subscriptions. What I’d Like to Receive From You • relevant iOS apps you have built before • experience with subscription apps • experience with AI / pose detection / rep counting • estimated cost and delivery time • your suggested tech stack and approach

I can help with this, I will build your fitness-gated productivity app in Swift/SwiftUI — exercise detection via Vision framework, app-blocking logic using Screen Time API, and full StoreKit 2 subscription integration with paywall and onboarding. For rep counting, I will use Apple's Vision body pose detection entirely on-device — no server needed. This keeps latency low and satisfies App Review privacy requirements cleanly. Questions: 1) Do you have a specific unlock duration range in mind — e.g., 5, 15, 30 minutes? 2) Should the free version allow one blocked app with limited exercises, or a time-limited trial? Looking forward to your response. Best regards, Kamran

Hi, I’ve reviewed your requirement and this is a unique iOS app where the main challenge is reliable app-blocking + accurate on-device rep detection. We’ll handle this as a professional team and build a clean, subscription-driven iPhone app using Swift + SwiftUI. For pose detection and rep counting, we’ll use Apple Vision + Core ML to keep processing on-device for speed and privacy. One important note: iOS does not allow full blocking of third-party apps like Instagram/TikTok. The closest reliable approach is using Screen Time / FamilyControls APIs (with permissions) or a controlled “lock overlay” + behavior-based flow. We’ll design this carefully so it aligns with App Store guidelines. Core system will include exercise detection (push-ups, squats, sit-ups), configurable reps, unlock duration, onboarding, progress tracking, and a clean paywall with StoreKit subscriptions (monthly/yearly + trial). UI will stay minimal and motivating, focused on quick interactions before unlocking apps. Estimated timeline: 4-5 weeks for MVP. Happy to share similar work and plan this step-by-step.

HELLO, I have 8+ years of experience in iOS development, building performance-focused apps with Swift and SwiftUI, including subscription-based products and apps using camera/AI features. I’ve successfully delivered similar concepts and can present relevant work involving StoreKit, user engagement flows, and real-time detection systems. Your idea is strong, and I can build this as a smooth, iPhone-first experience with a clean UI and reliable performance. I’ll implement app selection logic, exercise-gated unlocking, and configurable timers, along with a seamless onboarding and paywall using StoreKit (monthly/yearly + trial). For rep counting, I’ll use Vision + Core ML for on-device pose detection to ensure privacy and low latency. The architecture will be modular and scalable, handling state management, background behavior, and analytics cleanly. I’ll also focus on UX—making the flow motivating rather than intrusive, which is key for retention. Thanks.

Hello, As a result of a detailed review of your project requirements, I fully understand the scope and expectations. I have experience building iOS apps with camera-based features and subscription models, and I’m available to start right now. I bring strong expertise in Swift, SwiftUI, iOS Development, StoreKit, Core ML, and Vision. The key challenge here is combining accurate pose detection with a smooth unlock flow while keeping everything privacy-friendly and responsive. I would structure this using on-device Vision/Core ML for rep counting, integrate StoreKit 2 for subscriptions, and build a clean SwiftUI onboarding and paywall flow with configurable unlock logic. I have a couple of quick answers and questions. I have built subscription-based apps using StoreKit with trials and renewals, and implemented camera-based tracking using Vision for motion detection. For your case, do you prefer a fully on-device ML model or a hybrid approach for better accuracy? Also, should app blocking rely on Screen Time APIs with user permissions? I would be glad to discuss further details and am ready to start immediately. Looking forward to hearing from you. Best regards, Carlos.
