Project Description
I’m building an Android-first fitness app that lets several independent gyms run on the same system while keeping their data completely separate. Each gym will have its own admin login (owner or trainer) and a roster of clients linked only to that gym.
The interface must feel professional and sleek and stick to a simple four-tab flow: Dashboard, Workout, Diet, Progress. Phone or e-mail sign-in is enough for this first release.
Core admin features
• Add and manage members for one gym only
• Create and assign workout plans and diet plans
• Review member progress in real time
Core user features
• Log workouts via dropdown menus for sets, reps, and weight
• Enter calories, protein, and water intake manually
• Track weight, body measurements, and optional progress photos
• View charts of their own data only
Technical essentials
• Android build delivered as APK plus full source (Kotlin, Flutter, or React Native—open to your suggestion)
• Secure multi-tenant backend where every record is tied to a single gym, preventing cross-access
• Clean, extendable codebase; no AI modules or complex third-party integrations for now
Timeline & hand-off
I need the complete MVP in my hands within 10 days, including a short walkthrough and documentation that lets me spin up new gyms quickly.
When you reply, please show at least one similar app you have shipped, outline your proposed tech stack, give a milestone-based cost breakdown for this MVP, and describe how you will guarantee tenant isolation and data security.
