Is your fitness wearable actually tracking your heart rate correctly? CombiFitTrack lets you find out. CombiFitTrack is a real-time heart rate comparison tool that connects to multiple fitness devices simultaneously — Whoop, Apple Watch and Polar H10 chest strap — so you can see exactly how each one performs during your workouts. COMPARE HEART RATE FROM 3 DEVICES Connect your Whoop band, Apple Watch and Polar H10 at the same time. See live BPM from each device side by side on one screen. Choose to track from a single source or use the average of all connected devices. FULLSCREEN GYM DISPLAY Giant heart rate display designed to be visible from across the gym. Tap to switch between Whoop, Watch and Polar as your active source. Perfect for keeping an eye on your BPM during intense sessions. COOLDOWN COUNTDOWN Start a 2-minute cooldown timer at the end of your workout. The app automatically stops and saves when the countdown finishes, giving you accurate recovery data without having to remember to stop manually. HEART RATE RECOVERY ANALYSIS After every workout, CombiFitTrack analyses your heart rate recovery (HRR). See your HRR1 (1-minute drop) and HRR2 (2-minute drop), peak and recovered BPM, and get a rating from Excellent to Poor based on medical benchmarks. CALORIE TRACKING Automatic calorie calculation using watts-based, HR-based (Keytel et al.), or MET formulas depending on available data. Tap the info button to see exactly how your calories were calculated. 30+ ACTIVITY TYPES Choose from running, cycling, swimming, rowing, weightlifting, boxing, yoga and many more. Track which body position each device was worn on for every workout. CUSTOMISE YOUR LOOK Pick any accent colour with the colour picker or choose from quick presets. 6 background styles: Rainbow, Stripes, Diagonal, Bubbles, Waves and Solid. Adjust background brightness with the slider. All styles sync to your Apple Watch. APPLE WATCH COMPANION Dedicated Watch app tracks your heart rate independently. Synced themes and accent colours. The Watch keeps tracking even after you stop on iPhone — no need to restart. WORKOUT HISTORY & EXPORT Review all past workouts with detailed charts showing HR data from every device. Export workout data as JSON for analysis. Recalculate calories using different HR sources. LIVE ACTIVITY See your heart rate on your Lock Screen during workouts with the Live Activity widget. Stays updated even when the app is in the background. PRIVACY FIRST All data stays on your device. Optional Apple Health integration to save workouts. No accounts, no cloud, no tracking. ## Version history (last 3 releases) ### 1.3.0 — 2026-04-08 What's new in v1.3.0: GARMIN SUPPORT - Connect Garmin heart rate monitors alongside Whoop, Apple Watch, and Polar H10 - Compare up to 4 devices simultaneously during workouts DEVICE PICKER - Choose which devices to show on your dashboard in Settings - Enable or disable Whoop, Apple Watch, Polar H10, and Garmin individually THEME CUSTOMISATION - Pick any accent colour with the colour picker or choose from 8 quick presets - 6 background styles: Rainbow, Stripes, Diagonal, Bubbles, Warp, Solid - Adjust background brightness with the slider - All styles sync to your Apple Watch COOLDOWN COUNTDOWN - Start a 2-minute cooldown timer during high-intensity workouts - Heart turns cyan blue during cooldown for clear visual feedback - Auto-stops and saves when countdown finishes - Only available after 10+ minutes with HR above 120 BPM HEART RATE RECOVERY - Automatic HRR1 and HRR2 analysis after every workout - Recovery rating from Excellent to Poor based on medical benchmarks - Visual chart overlay showing your recovery period FULLSCREEN VIEW - Pinch to zoom: spread fingers for bigger timer, pinch for bigger heart - Clock display moved to top-right corner for better visibility - Start and stop buttons available directly in fullscreen - Calorie formula now shown via info button instead of separate card OTHER IMPROVEMENTS - Workout history only shows devices that were active during each session - Forgotten workout notification after 15 minutes in background - Apple Watch keeps tracking independently after iPhone stops - Battery indicators on animated background themes - Cooldown timer continues accurately even when app is in background - Live Activity updates more frequently on lock screen - Device selection syncs between workout view and fullscreen view - Compact Apple Watch layout fits all screen sizes without scrolling ### 1.2.0 — 2026-03-18 - Theme system revamp: choose any accent colour with the colour picker, or pick from 8 quick presets - 6 background styles: Rainbow, Stripes, Diagonal, Bubbles, Waves, Solid - Background brightness slider to adjust how dark or light your theme appears - Cooldown countdown: start a 2-minute cooldown timer during workouts — auto-stops when finished - Heart rate recovery analysis (HRR1 & HRR2) with rating after every workout - Recovery chart overlay showing exactly where your heart rate dropped - Calorie formula info button — tap to see how your calories were calculated - Battery indicators on animated background themes - Apple Watch now keeps tracking independently after iPhone stops - Background styles sync to Apple Watch - Bug fixes and performance improvements ### 1.0 — 2026-03-08 No release notes. ## Apps similar to Combi Fit Track | App | Rating | Price | Category | | --- | --- | --- | --- | | [sleep² sleeptracker & analysis](https://appshunter.io/ios/app/sleep-sleeptracker-and-analysis/id1629426238) | 3.4 (34) | Free | Health & Fitness | | [SleepSpace: Deep Sleep Tonight](https://appshunter.io/ios/app/sleepspace-deep-sleep-tonight/id1193763939) | 4.2 (855) | Free | Health & Fitness | | [Streaks](https://appshunter.io/ios/app/streaks/id963034692) | 4.8 (27,345) | $5.99 | Health & Fitness | | [Wings for Life World Run](https://appshunter.io/ios/app/wings-for-life-world-run/id956816207) | 4.9 (1,277) | Free | Health & Fitness | | [Philips Sonicare For Kids](https://appshunter.io/ios/app/philips-sonicare-for-kids/id1002285219) | 4.7 (11,901) | Free | Health & Fitness | | [Boostcamp: Workout Programs](https://appshunter.io/ios/app/boostcamp-workout-programs/id1529354455) | 4.8 (9,725) | Free | Health & Fitness | ## More apps by Martynas Prascevicius - [ROK Players Log](https://appshunter.io/ios/app/rok-players-log/id6758787828) - [NutriTrack + AI](https://appshunter.io/ios/app/nutritrack-plus-ai/id6758859001) All apps by Martynas Prascevicius: https://appshunter.io/developer/1816574561 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
