1
Design the onboarding and goal-setting flow
Prototype fitness goal selection, current level assessment, schedule preference, and plan recommendation screens. The quality of this flow determines long-term retention more than any feature.

How to build it with AppForceStudio
2
Build the workout library and session screens
Generate exercise browsing, workout detail, active session timer, rest timer, and exercise substitution flows. Validate that in-workout navigation requires minimal cognitive load.
3
Create the progress tracking dashboard
Design workout history, personal records, streak visualisation, body metrics tracking, and before/after comparison screens that give users visible evidence of their progress.
4
Add nutrition and habit tracking
Prototype the meal logging screen, macro summary dashboard, water intake tracker, and daily habit checklist that complement workout tracking.
5
Build the coaching and community layer
Design coach assignment, programme delivery, in-app messaging, and community challenge screens for apps that include a human coaching component.
Common Challenges
Problems to design for before you build
Day 7 drop-off is the biggest fitness app problem
Most users stop using fitness apps within their first week. Design re-engagement screens, streak mechanics, and progressive difficulty signals to fight this before building features.
In-workout UX must require zero cognitive effort
Users in the middle of a set cannot read dense screens or make multiple taps. Validate that every in-workout interaction works with sweaty hands and high heart rate.
Personalisation expectations are high
Users expect fitness plans that adapt to their schedule, equipment, and progress. Prototype the adaptive plan flow before deciding how to implement personalisation logic.
