RankTime

Record once. RankTime learns the movement, then counts every rep for you: pushups, squats, snatches, kettlebell swings, anything you train it on. No account. No login. Your data syncs through your own iCloud, not our servers. 7 days free, then $9.99/month or $99.99 once. A FULL MURPH, COUNTED 100 pullups. 200 pushups. 300 squats. All three come ready to count. Put the phone down and don't touch it again. RankTime counts every rep as you move through them. No tapping between movements, no stopping to type a number in, no trying to remember where you were at squat 180. Just the workout. TWO WAYS TO COUNT Point the camera and RankTime reads your body position to count reps. Or strap on a Polar H10 and it counts from the accelerometer instead: phone in your pocket, outdoors, in the dark, at any angle. Same precision, your choice. TRAINS ON ANY EXERCISE Record one set. RankTime learns the signature of that movement and counts it from then on. Put up to 3 exercises in a workout and it tracks each one separately. HEART RATE, PROPERLY Polar H10 over the official SDK for beat-accurate HR and RR intervals, or any standard Bluetooth monitor. Live during the workout, burned into your recording, and saved to Apple Health. YOUR WORKOUT ON VIDEO Record the set with the timer, rep count and heart rate drawn straight into the footage. Check your own form afterwards, or share it as it is. PROGRESS YOU CAN SEE Guided progress photos keep the same framing every time. The progress movie plays them oldest to newest, with each rank insignia appearing on the frame where you earned it. Export it to Photos in one tap. A COACH THAT READS YOUR HISTORY Weekly targets set from your own pace. Whether you are on track today, not just at week's end. Reps and pace trends against previous weeks. Longest streak, current streak, and a rank target calendar per exercise. EARN YOUR RANK Every rep counts toward promotion through 21 military ranks. Train three separate days in a week to earn that week's decoration: commendations, bronze stars, silver stars, medals of honor. BUILT-IN WORKOUTS TABATA and EMOM on the clock for HIIT. CENTURION and MURPH on reps for calisthenics. CINDY and PUSHUP TEST on AMRAP. Add a GPS run before or after any workout. Ladder mode for climbing sets. Or build your own from work, rest, rounds and exercises. EVERYWHERE YOU TRAIN Apple Health for workouts and heart rate. iCloud sync across your devices with no login. It uses the Apple Account already on the phone. Home screen widget for your next session. PRIVATE BY DEFAULT There is no RankTime account, because there is nothing to log in to. Sync runs on the Apple Account already signed in to your phone, straight to your own private iCloud: your workouts, your photos, your measurements, in your storage, under your control. Analytics are off until you switch them on, and stay off if you never do. Body measurements and progress photos are encrypted on the device. Your training video stays in your camera roll unless you share it yourself. Subscription: RankTime Pro is $9.99/month with a 7-day free trial, or $99.99 once for lifetime access. Payment is charged to your Apple Account at confirmation of purchase. Monthly subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the period ends. Manage or cancel in your Apple Account settings. Any unused portion of the free trial is forfeited when you purchase.

Verdict
The clearest difference is in-app purchases: BioForce HRV at none against RankTime's 7. BioForce HRV also leads on iOS requirement (8.0 vs 26.0). RankTime's advantage is update cadence (every 3 weeks vs every 9 months). On price, ads and device support there is nothing between them.
