Built for fitness operators
A fitness app needs three things to work: membership billing that runs free trials through paid tiers, an AI coach that adapts to each member, and a mobile app your members actually open. Base44 delivers all three from one codebase. The commerce kit that runs Stratton Oakmont's $49.99/mo tiers runs your gym memberships; the AI agent pattern that triages jobs in FieldIQ and triages claims in ClaimAssist triages a member's goals into a workout plan; the realtime subscriptions behind TablePulse's kitchen board power live class booking and leaderboards.
Why Base44 for fitness apps
Base44's commerce kit handles subscription billing, free trials and upgrades without stitching in a third-party billing engine. AI agents built on InvokeLLM deliver a conversational coach that reads a member's history, fatigue and goals and proposes the next session. Realtime subscriptions push live class capacity and leaderboard updates to every device. The mobile compiler ships the same React codebase to iOS and Android — the same build that powers RimIQ and FieldIQ on phones today.
Engagement & pricing

Proof the patterns ship
The building blocks are already live: subscription billing (Stratton Oakmont, 12 days), AI agents in production (FieldIQ dispatch, ClaimAssist claims), realtime live boards (TablePulse, 9 days), and native mobile from one codebase (RimIQ, FieldIQ). A fitness app reuses every one of these proven patterns — which is why it lands in days, not quarters.
Questions, answered.
What can a Base44 developer build for a fitness business?
Membership and subscription billing, an AI coaching agent that adapts workouts, workout and stat tracking with leaderboards, live class booking, and a native iOS/Android app — all from one Base44 codebase. The patterns are proven across live portfolio builds.
Can the app handle gym memberships and subscriptions?
Yes. The commerce kit that runs Stratton Oakmont's tiered subscriptions (free → $49.99/mo) handles free trials, paid tiers, upgrades and cancellations — the same engine runs your memberships.
Can I add an AI coach?
Yes. The AI agent pattern behind FieldIQ's dispatch and ClaimAssist's claims works for coaching: an agent reads a member's history, fatigue and goals and proposes the next workout, answering questions conversationally in chat.
Does the app work on iOS and Android?
Yes. Base44 compiles the same React codebase to native iOS and Android — the same mobile build that ships RimIQ and FieldIQ. No separate port, no second codebase.
How much does a fitness Base44 build cost?
