RefineSimple: Strength Log

RefineSimple is the strength-training app for people who take it seriously — with a plan that adapts to your body instead of forcing you through a fixed scheme.

ADAPTIVE
Your week isn't a rigid calendar, it's a pool of sessions. Each morning your readiness score picks the best one for today: recovered → your heavy day, wiped → something lighter or a real rest day, no guilt. Underneath runs a real mesocycle with deload weeks and automatic progression that follows your sets.

EXPLAINABLE
No black box. Every recommendation names the strongest reason with a number — "HRV below baseline, sleep −21% → less volume today." You always understand why the app suggests something.

YOU STAY IN CONTROL
The app never says "don't train." It shows you why it recommends an adjustment today — accept or keep the original plan, one tap.

READINESS THAT'S YOURS
Your readiness score comes from HRV, sleep, resting heart rate and training load, straight from Apple Health. Instead of generic numbers, the app learns your personal typical range, shows the real trend and a 14-day history — reconstructed on first launch.

YOUR AI COACH
A coach that knows your recent sessions, your readiness score and every set you've logged — and answers based on them. It swaps an exercise when a joint acts up, cuts volume when needed, and explains its decisions. No motivational fluff.

PROGRESS, HONESTLY COUNTED
Automatic PR detection via estimated 1RM — a rep PR counts too (100 kg × 8 instead of × 5). e1RM trend per exercise, tonnage and volume per muscle group against science-based landmarks.

No nutrition tracking, no social features, no fluff. Just intelligent strength training that adapts to you.

RefineSimple Pro unlocks the AI coach and all workouts.
