Gym apps wanted $15/month for a notebook with a timer. So I decided it was up to me — to build my own, and give it to the people who deserve it… everyone. Auto-filled sets, instant PR trophies, a coach that actually coaches. Free. Forever.

⚡ THE SMART LOGGER — TRY IT RIGHT HERE
Type a weight. Beat your best.
Your last session is already filled in — just beat the numbers. Go above your best and a gold trophy fires instantly. Watch your estimated 1-rep-max climb as you type, and The Coach tells you exactly what to do next. This is the real thing, live below.
🏆
Goblet Squat
Last: 50×10, 50×10, 50×10 · best 50 lbs · Est 1RM:
67 lbs
COACH
Stay at 50 lbs and get every set to 12+ reps first.
#WEIGHTREPSRPE1RM
↑ Try typing 235 in a weight box — watch the trophy fire.
🏆 Live PR detection
Type a weight above your best and the trophy fires the instant you cross it — no save button, no waiting.
📈 Live e1RM (Epley)
Your estimated one-rep max recalculates with every keystroke, so you always know where you stand.
🧠 The Coach
Rule-based progressive overload: top the rep range and it tells you to add weight. Stall out and it suggests a deload.
🛟 Crash-proof
Saves from the second you start. Phone dies mid-workout? Nothing lost — "resume workout" is waiting.
THE HEADLINERS
Everything a paid app does.
Everything a paid app does.
None of the price.
The Smart Logger
Auto-fills your last session so you just beat it. Live PR trophies, live Epley 1RM, and The Coach calling progressive overload per lift. Logs weight, reps and RPE — and it's crash-proof from set one.
- Auto-fill from last session
- Instant gold-trophy PRs
- Stagnation & deload warnings
Timers that survive a dead phone
Every timer beeps and is anchored to the wall clock — accurate even if the app is closed or your screen's off. Whole-session timer, opt-in auto rest timer with 3-2-1 beeps, a single hold timer for planks, and a full-screen HIIT interval runner.
- Full-screen interval runner (work/rest rounds)
- Beeps + vibration, screen stays awake
- Auto rest timer, 3-2-1 countdown
Build your own split
Unlimited custom programs: name it, pick a theme color, set the days, add exercises with sets, reps, rep-targets, timed holds or intervals, descriptions, and your own YouTube form links. Two pro programs are built in, free.
- Difficulty color-coding per day
- Per-exercise & whole-workout notes
- Plate calculator + tap-to-watch form videos
A progress dashboard that hypes you
Training calendar (green = trained, gold trophy = PR day, blue = weigh-in), a streak system, auto weekly review insights, and milestone badges with confetti when you hit them.
- Current / longest streak + monthly %
- Auto weekly review
- Tap any day for the full session
Strength levels & charts that draw themselves
Progression charts animate as they draw. Bench, Squat and Deadlift get graded Novice → Intermediate → Advanced → Elite against your bodyweight — showing the exact weight that unlocks the next tier.
- Strength tiers vs bodyweight
- Animated strength progression
- Bodyweight tracking, 7-day average & trend

THE INTERVAL RUNNER
Full-screen.
Full-screen.
Loud. Relentless.
Set your work/rest rounds and go. Giant countdown, audible beeps, haptic buzz, and the screen stays awake the whole time. WORK turns the screen green. REST turns it gold. No squinting at tiny numbers between rounds.
