Cross-Platform Fitness Tracker App

I need a polished mobile application that works seamlessly on both iOS and Android. The core of the build is a dual-tracker: one side lets users record detailed workouts, the other keeps daily calories and macros in check.

Workout tracking must cover strength training, cardio, and flexibility routines with fields for exercises, sets, reps, weight, and a searchable history. On the nutrition side, users should be able to log meals by snapping a quick photo or speaking the entry, after which calories, protein, carbs, and fats are stored and shown in a clean daily log.

A progress dashboard will surface daily and weekly trends through intuitive charts—think personal records, streaks, and macro balance visualisations. Each user should have a secure account so their data syncs reliably across devices.

Performance, fast load times, and a visually simple UI are key; I’m happy for you to choose the best cross-platform stack (Flutter, React Native, Kotlin Multiplatform, or another robust option) provided it delivers a native-feeling experience.

Deliverables
• Fully functional iOS & Android apps ready for App Store / Play Store submission
• Source code and build instructions
• Lightweight, modern UI that passes design hand-off files (Figma or similar)
• Secure user authentication and cloud data storage
• Basic analytics module powering the progress dashboard

Acceptance criteria
• Exercise and meal entries save instantly and remain available after reinstall/login on a new device
• Chart data matches underlying logs within a 1% tolerance
• App launches to first interactive screen in under three seconds on mid-range devices

If you can marry speed, reliability, and a crisp interface, I’m ready to get started.
