Coil 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.
It is built around rotational power, so it suits golfers and anyone chasing speed as much as size. Driver clubhead speed and vertical jump sit alongside your key lifts as benchmarks. It works just as well as a straight strength program.
Answer four quick questions about your goals, how often you train, the kit you actually have, and any injuries, and Coil builds a program around you, swapping out anything that aggravates a niggle. Prefer a proven template? Start with the Balanced Hybrid 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
IT READS YOUR NOTES
• Say how a session felt and Coil proposes one change to what comes next
• Every proposal quotes your own words back and waits for a tap. Nothing changes behind your back
• Undo restores the program exactly, and Coil drops the subject for two weeks
BUILT AROUND WHAT YOU HAVE
• Tell Coil your kit, from a full gym to a couple of kettlebells to nothing at all
• Sets, reps and RPE targets scale from new lifter to advanced
• Swap any exercise for today or for good, filtered by your injuries, your kit and what you like
• Anything you do not have the kit for is flagged, with a one-tap swap
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, including timer-only days
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
Coil is built to get out of your way. Open it, train, log, leave.
