Create a subscription-based app for both Apple Store and Google Store and also get those apps uploaded to those stores. I have created an app using Base44 AI which I am happy with as far as the appearance and function. However, they don't have to tools to enable the subscription-based function. The app is very basic, I created an Excel worksheet that performs simple functions and the app is to present that data, along with ability of the user to input background information that the worksheet utilizes to make the calculations. It's essentially a tool that gives real estate beginners the ability to input variable info in order to determine if the property is a good deal. The app needs to be visually professional, easy to read/display, and also include a pdf download capability of the information.

I can help with this, I will build your real estate evaluation app for iOS and Android — subscription management, the calculation engine from your Excel logic, user input forms, and PDF export — then handle submission to both app stores. For subscriptions, I will wire in RevenueCat to manage Apple and Google billing from a single integration. This keeps receipt validation, trial periods, and renewal logic off your plate and avoids the common pitfall of handling each store's subscription API separately. Questions: 1) Do you have the Excel formulas documented, or will I extract them from the spreadsheet directly? 2) Which subscription model do you prefer — monthly, annual, or tiered options? Send me a message and we can go over the details. Best regards, Kamran

This is a pretty common gap when an AI-built app already feels right visually but isn’t wired for real-world monetization and store requirements. I’d start by keeping your current logic and screens in mind, then properly layering in Apple/Google in-app purchases so subscriptions actually control access in a reliable way, including receipt validation and restore purchases so users don’t get locked out after reinstalling. Next step would be translating your Excel-style calculations into a clean, deterministic logic layer so inputs always produce consistent deal analysis across devices. Once that’s stable, I’d connect it to a simple PDF generator so users can export a formatted deal report directly from their inputs. I’d also make sure edge cases are handled early—like offline usage, partial inputs, and subscription state drift between devices. One small but meaningful upgrade would be letting users save and compare multiple property scenarios instead of recalculating from scratch each time. I can also handle full App Store + Play Store submission and approvals. Are you planning to keep the Base44 interface as-is, or are you open to refining the UI slightly for a more native mobile feel?

Hi there, You’ve already solved the hard part: the app’s look and flow. The hidden gap is turning that solid Base44 experience into a real subscription product that feels polished, works cleanly on iOS and Android, and gets approved without store friction. I can bridge that gap by adding subscription logic, secure user input handling, PDF export, and the App Store / Google Play submission setup. With 15+ years in mobile and backend development, I’ll map your Excel-style calculation logic into a reliable app workflow, keep the UI easy to read for beginners, and integrate the right in-app purchase/subscription approach for both platforms. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. Can you confirm whether you want subscriptions handled through Apple/Google in-app purchases, or via an external billing system tied to user accounts? I can start by reviewing the current Base44 build, the worksheet logic, and the attached screens, then outline the cleanest path to launch. Best regards, Asad

Hi, this project involves extending a real estate evaluation app with subscription capabilities and multi-platform deployment, which presents integration and orchestration challenges. I usually structure systems by separating data ingestion, business logic, and frontend presentation layers to maintain clarity and scalability. I've built several production systems that integrate custom calculation engines with user input and output flows. My experience with Custom Feature Development & Integration directly relates to enhancing existing apps with new features while ensuring maintainability and clean architecture. I recommend separating the subscription management from the core calculation logic to allow independent scaling and easier compliance with app store requirements. Although LLM reliability signals are not directly relevant here, ensuring robust data validation and error handling around user inputs and calculation outputs is critical. Systems like this should be designed for long-term production use with clear documentation and upgrade paths. I can outline the integration pipeline for the calculation engine, map the subscription flow, and review the PDF generation strategy. Thanks, Hercules

Hello, I understand you need a subscription-based real estate evaluation app for iOS and Android, based on your existing Base44 AI prototype, where users input property data, run simplified calculations (Excel-like logic), view results clearly, and download reports as PDFs. I will convert your current concept into a production-ready mobile application with a clean, professional UI and subscription system integrated for both Apple App Store and Google Play Store. The app will include secure user authentication, tiered subscription access (monthly/annual), and backend-controlled feature gating so only paying users can access full evaluation tools. The core logic from your Excel worksheet will be rebuilt into a reliable backend calculation engine (or embedded service layer), ensuring consistent and accurate results across all devices. Users will be able to input property details, instantly receive investment analysis results, and export a formatted PDF report with branding and structured insights. I will also handle App Store + Play Store deployment, including subscription setup via Apple In-App Purchase and Google Play Billing, ensuring compliance and smooth approval. The UI will be optimized for readability, fast input, and beginner-friendly real estate decision support. You can also view my portfolio here: https://www.freelancer.com/u/Feriver Thanks, Asif
