I run an established online fitness coaching platform that delivers training programs, diet guidance and educational content to paying clients. The web version works, but it now needs a serious tune-up and, most importantly, a companion mobile app for both Android and iOS. What I want to tackle first is performance and speed—I need pages to load fast and videos to stream smoothly. At the same time, the overall user experience and usability must feel modern and intuitive, so clients can find their plans without hunting through menus. Finally, several automations (payments, email sequences, progress-sheet syncing and calendar reminders) have to be refactored and re-connected so they run reliably in the background. For the app itself my must-have features are: • secure login tied to the existing user database • instant access to diet plans and progress tracking dashboards If bringing training-plan content in natively is straightforward, I’m open to discussing that as an early enhancement. Preferred tech: Flutter, React Native or a high-quality WebView wrapper that hooks cleanly into my current site. Whichever route we choose, I need builds submitted to both the Apple App Store and Google Play Store. Deliverables • Optimised web platform (speed, UX, automations) • Cross-platform mobile app connected to the same backend • Store-ready binaries and basic release notes Please include links to similar health, fitness or coaching apps you’ve shipped, along with a ballpark cost and timeline for each milestone. I’m looking for someone interested in an ongoing partnership, so let me know how you typically handle post-launch support and iterative feature work.
