I'll develop a mobile workout diary app

I do turnkey mobile app development for workout diaries — from idea and prototype to finished app. I'm regularly asked for exactly this niche: not a universal fitness suite with calorie calculator and habit tracker, but a specific tool for recording workouts, where an athlete quickly enters exercise, number of sets, reps, and working weight without getting distracted by extra screens.

I pay special attention to the progress chart: the user should see how their working weight or volume for each exercise changes over weeks and months, not manually scroll through history. Another feature I ask clients not to remove from the specification is repeating the last workout with one button: the app substitutes exercises and numbers from the last session, and the user adjusts what changed. This small detail usually decides whether someone will return to the app in the second week or not.

I work with both native development and cross-platform solutions — choice depends on budget and timeline. I set up local data storage or server synchronization, provide source code and working build for review.
