StriveAI.

AI-powered fitness coach that adapts to you.

The work

Most fitness apps hand you a static plan on day one and never change it. The plan doesn't know if you skipped a session, hit a new PR, or changed your goals — and your results reflect that.

StriveAI combines structured workout programming with AI-driven analysis. The platform builds a plan from your goals, tracks every session, and continuously adapts the next week of training based on what you actually do. Native on every device, built on a single codebase.

01 / 04

Adaptive training plans

Plans are generated from your goals, then updated weekly based on what you actually do. Skip a session, push harder, change your timeline — the next week reflects it.

02 / 04

Real progress tracking

Every set, every rep, every session feeds the model. The longer you use StriveAI, the more precisely it understands your training capacity and recovery.

03 / 04

AI-driven analysis

The platform reads patterns in your training — volume, intensity, frequency, plateaus — and adjusts the next block of programming to keep you moving forward.

04 / 04

Native on every device

iOS, Android, and web from a single TypeScript codebase via Capacitor. The same data, the same plan, the same experience — wherever you train.
