I’m building the first “AllTrails-style” guide dedicated to obstacle-course racing (OCR) training spots and need a production-ready mobile application that runs smoothly on Both iOS and Android. The core experience hinges on a live map (Google Maps API or comparable) where users can drop pins, attach geo-tagged photos, write descriptions such as “Great for rope climbs—public park with pull-up bars,” rate the spot, and tag it with OCR-specific attributes like grip strength, endurance, or mud terrain. Beyond discovery, the app must feel social. Logged-in athletes should be able to comment, favourite, post challenges (“Beat my time at this spot”), and build simple public profiles. Powerful filters—difficulty, obstacle type, proximity, user reviews—help people find exactly what they need. Because many venues change with weather or land-owner rules, each listing also houses safety notes distinguishing public versus private access and weather-dependent restrictions. I’m starting a new enterprise, so a clean, scalable codebase matters. A modern cross-platform framework (Flutter, React Native, or similar) with Firebase/Auth0 sign-in, secure photo storage, and a modest admin dashboard for content moderation will keep future costs down. Deliverables • Complete source code for Both iOS and Android builds • Integrated map with pin creation, photo upload, rating, and OCR tag support • User authentication, profiles, favourites, comments, and challenge tracking • Filter and search logic operating on obstacle type, difficulty, proximity, and reviews • Basic admin panel for approving or flagging user-generated content • Deployment guidance to App Store and Google Play Please include detailed project proposals outlining technical approach, timeline, third-party services, and post-launch support so I can assess the best fit for this venture.
