Inside the App
Everything you need to know about tracking workouts, competing against yourself, and building a better training habit.
Core Feature
A single number from 0 to 1,000 that reflects your weekly training quality. It updates in real time as you work out and resets each week—so you always have a fresh target.
Total training load from strength sessions—sets, reps, and weight lifted. Heavier and higher-volume workouts earn more.
A blend of active minutes and calories burned. Rewards both duration and workout intensity throughout the week.
How regularly you show up. Every day with at least 15 minutes of training counts toward your consistency target.
Rewards well-rounded training. Hit all major muscle groups, train body parts more than once, and maintain regular cardio.
Your win rate from You vs You challenges. Beat your past self to earn points. If you don't compete, these points redistribute across the other four.
Rewarding variety over repetition
Scoring Detail
Coverage rewards you for training a variety of body parts rather than repeating the same muscles every session. It has three sub-components.
Train as many of the 7 major muscle groups as possible each week. More groups covered means more points earned.
Train muscle groups on two or more separate days. Hitting a body part twice shows serious commitment to growth.
Regular cardio sessions throughout the week. Running, cycling, rowing, or any cardio activity counts toward this target.
Arms includes biceps and triceps. Posterior chain includes hamstrings and glutes. Full-body exercises count toward all seven groups.
Training frequency — if you train 2 days/week, you need to hit fewer groups than someone training 5+ days.
Age — targets are slightly reduced for users over 50 to reflect realistic training volume.
Sex — female users get a slight shift toward cardio weighting in the sub-component balance.
Your past self is your next opponent
Core Feature
Every workout creates a ghost—a record of what you did last time. Your next session becomes a race to beat it.
Before starting, choose who to compete against: your last session, your personal best, the average of your last 5, or any past workout.
During your workout, a ghost line shows your opponent's heart rate alongside yours. Track calorie pace, intensity, and volume against the ghost in real time.
Real-time badges show whether you're ahead or behind. For strength: volume and sets. For cardio: calories and intensity. For mixed: a combined score.
After finishing, a detailed scorecard shows how you compared—with percentage improvements across every metric. Wins count toward your Fitness Score.
Any standard BLE monitor, zero brand lock-in
Hardware Integration
Connect any Bluetooth heart rate monitor for live tracking during workouts. Your heart rate data powers calorie calculations, intensity scoring, and ghost comparisons.
Works with any Bluetooth heart rate monitor that broadcasts the standard Heart Rate Service—Polar, Wahoo, Garmin, Coospo, and more.
Heart rate keeps recording when you lock your phone or switch apps. A native foreground service maintains the BLE connection so you never miss a beat.
A real-time heart rate chart scrolls during your workout, showing your current BPM alongside your ghost's heart rate for visual comparison.
With a connected HR monitor, calories use the Keytel (2005) formula—factoring heart rate, age, sex, and weight for research-backed accuracy.
From first rep to weekly recap
Core Feature
Create custom workouts, log every set in real time, and track cardio with distance, pace, and calories. Everything builds toward your weekly goals.
Build workouts from a library of 200+ exercises across strength, cardio, and mixed categories. Set target sets, reps, and weights for each exercise.
One-tap set tracking: Start Set, perform your reps, End Set. Adjust reps and weight inline. Rest time is auto-calculated between sets.
Log cardio with duration, distance, and calories. Enable GPS for outdoor activities like running and cycling to capture route, pace, and distance.
Your Data
Your workout data lives on your device. No ads, no data sales, no uploads unless you choose to share.
Workouts, heart rate, GPS tracks, scores, and body composition are stored in an on-device database. Nothing leaves your phone unless you choose to share or export it.
Manual and automatic backups save your entire database as a JSON file. Restore from any backup to recover your data on a new device.
Social features are opt-in. Sign in with a magic link to add friends, share workouts, and challenge each other. Only workout summaries are shared—never raw heart rate or GPS data.
