Mobile Training With Signal, Not Noise

The best training app is the one you can use between sets without losing the set.

Principles

• Keep set logging fast with clear controls and prefill preferences.
• Preserve the details that change the meaning of a set: grip, assist, tempo, equipment, range, lean, and time.
• Show target muscles and recovery context where they help the next training choice.
• Keep core records local-first so a weak connection does not break the workout.

Speed matters, but not at the cost of mushy data. Fit Horizon is trying to make detailed tracking feel like a sharp tool, not a form to fill out.
