## What is Coil?

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.

## Version history (last 3 releases)

### 1.2 — 2026-09-17

Your notes shape your program.

• Hybrid Build is now Coil. Same app, same data, new name.
• Logging is now organized by session, not by date. A movement you trained earlier in the week no longer shows as already done today.
• Tell Coil how a session went and it proposes one change to what comes next, quoting your own note back to you. Accept it or ignore it, and every change is reversible.
• Preview any session before you start it, and close it out with a summary of what you actually did.
• EMOM and for-time blocks are logged and counted now, so a timer-only day shows up in your history.
• Supersets are paired only when the two movements genuinely work together, and a "gym is busy" toggle runs paired blocks as straight sets.

### 1.1 — 2026-08-03

1.1 Make the program yours.

• Swap any exercise — pick an alternative for just today, or set it as your default. Suggestions respect your injuries, your kit, and what you actually like.
• Tell the app what equipment you have. Full gym, a couple of kettlebells, or nothing at all — your program is built from what you can actually use.
• Set your training experience. Sets, reps and RPE targets now scale from new lifter to advanced.
• Session notes — record how the whole session felt, not just individual sets.
• Clearer programming: exercises you don't have the kit for are flagged, with a one-tap swap.
