Hybrid Build – Gym Trainer

Your training program and every set, timer, and PR — all on your phone, fully offline. No account, no sign-up. Open it and train.

Hybrid Build is a focused, offline gym companion: follow a structured strength-and-power program, log every set in a couple of taps, and run the timers your session actually needs. No accounts, no feeds, no distractions — just you and the work.

Answer three quick questions — your goals, how often you train, and any injuries — and Hybrid Build generates a program around you, swapping out anything that aggravates a niggle. Prefer a proven template? Start with the Balanced Hybrid build instead.

FAST LOGGING • Big, thumb-friendly steppers for weight and reps • Optional RPE, per-side (L/R) tracking, and quick notes • Last-load prefill so repeat sets are near-instant • A 5-second undo on every entry

THE TIMERS YOU NEED • Rest timer that keeps the screen awake and alerts you even when the app is in the background • EMOM timer with round-by-round cues • "The Whip" for-time stopwatch with a movement checklist and automatic PR saving

TRACK WHAT MATTERS • Benchmarks for clubhead speed, vertical jump, key lifts, conditioning times, and Z2 heart rate • Trend sparklines and personal-best deltas so you can see progress at a glance • Full session history

YOURS, AND PRIVATE • Works 100% offline — no connection required • No account, no login, no tracking or analytics • Every set, session, and benchmark stays on your device • Export your whole training log and benchmarks to CSV whenever you want

Hybrid Build is built to get out of your way. Open it, train, log, leave.
