Even though the headphones are still connected to my iPhone. ### 3/5 — Не смог подключить AirPods *2026-07-06* Слишком сложные настройки. Очень неудобно. А AirPodsы нужны 3-го поколения, вот. **Developer response:** Вы пользуетесь AirPods Pro 3? Это единственная модель, способная отслеживать частоту сердечных сокращений. ### 3/5 — Almost perfect, need HealthKit write access *2026-05-18, version 7.0.2* Amazing app, almost perfect would be 5 stars if the app was able to write heart rate data to apple health kit. 3 other types of data can but not arguable the most valuable one, second by second heart rate for entire workouts, the one amazing thing the polar h10 can do, and why I’m using this app in the first place. ### 3/5 — The new version isn’t as useful as previously!! *2026-05-17, version 7.0.2* The new version isn’t as useful as previously Prior version ….. Older comments: What an amazingly good tool to create a foundation understanding about physical/cardiovascular health. I use it everyday because it captures reliably my stats and gives me options to compare different days. It also saves details for my primary care physician. Cannot tell you everything that is good/great about it ... it just is! ### 5/5 — Great HR tracker *2026-04-03, version 7.0.2* I paired this with a PowerLabs chest-strap heart rate tracker, and it works excellently. I particularly like the fact that Heart Graph is both very functional and also intuitively easy to use. Definitely worth it to purchase the three or four dollar premium option. ### 5/5 — Works as it should *2026-03-24, version 7.0.2* I have been a user for a year works as it should at no cost great value ### 5/5 — AirPod Pro 3 *2026-03-18, version 7.0.2* Nutzungsmöglichkeit als Herzschlagsensor wäre sehr schön! Im März 2026noch mal versucht zu verbinden - nun funktionieren sie,ich bin begeistert . Zu erwähnen ist die App verursacht über die Zeit keine Kosten. Das ist nur bei ganz wenigen so! ### 5/5 — Exactly what it says *2026-03-17, version 7.0.2* I’m an aging engineer and I love the simplicity of this app. It creates easy to understand graphs of my heart rate using only a commodity heart rate strap with no advertising and no tech giant to monetize my experience. Thank you! ### 5/5 — Love this app. *2026-03-14, version 7.0.2* Its simple, it works well and does what I need it to, its how an app should be. I use it to track my heart rate for running. It is easy to import workouts and the graphs are brilliant. I especially like the overlay feature so you can directly compare workouts. The appearance is simple and clear. The free version is great but after some time I decided to go for the paid version. ❤️ ### 5/5 — Straight forward excellent app that doesn’t want you to join their social club *2026-03-10, version 7.0.2* This app is excellent! It graphs your pulse frequency in a straight forward way. There is no sign-in, no gamification, it just works as it should. There are a few more advanced functions but those do not intrude on your normal user experience. I love it. Most other apps want to sell you a life style and constantly annoy you with notifications. This one only notifies you, when it’s important and useful. The free version is already useful enough but I paid the reasonable fee to set my own zones and to support maintenance. ### 2/5 — Good features but not intuitive *2026-02-10, version 7.0.2* I like some of your features. I’m a physiologist and I’m used to looking at graphs so I like your graphs. I wish it were possible to change the units. Sometimes it gets a bit crowded. Not intuitive. I can’t find my I can’t seem to repeat the same thing twice. It’s very confusing. ### 5/5 — Топ! *2026-02-08* Лучшее приложение для контроля чсс на иос. Респект разработчику 👍 ### 5/5 — Great app *2026-01-21, version 7.0* I use the Heart Graph app w/Polar HR10. Recently it looses signal with app and equipment receiver on treadmill 3 or 4 times in a 40 min walk/run. Seems to be a Polar issue, not the app. The app is very helpful. Wish I could find a better monitor. ### 5/5 — Audible alerts for heart rate zones *2026-01-21, version 7.0* Nice and simple app ### 5/5 — 5 Stars *2026-01-20, version 6.4.1* Excellent app with accurate, reliable tracking. ### 2/5 — Only works sporadically *2026-01-16, version 6.4.1* Works with pulsar monitors sometimes. Not reliable ### 5/5 — This app saved my life *2026-01-13, version 6.4.1* I have health issues that require me to stay in certain zones, and this is the best app I have ever found at setting zones and alerts, allowing me to workout and improve my health. THANK you to the developers!! ## Most critical reviews (10 lowest-rated) ### 1/5 — Does not sync consistently *2026-08-31, version 8.0.6* Just paid for the app and it does not sync. Tried 3 different hrms, rebooted devices etc. what utter garbage ### 1/5 — Slow *2026-06-25, version 8.0* Slow ### 1/5 — Can’t connect to my Polar H 10 *2026-01-12, version 6.4.1* I don’t have the patience to go through a trouble shooting routine again. I have other heart rate training apps that actually work. This one is useless to me. Will delete! ### 1/5 — Everything behind paywall *2026-01-08, version 6.4.1* Maybe it’s a good app, but I have no chance to evaluate it as everything is behind a paywall. I can’t even import my existing workout. So far just waste of my time. You should reconsider the payment model. ### 1/5 — Worthless *2025-06-02, version 6.3* Should be able to connect to any ant/ble sensors too limited for use ### 1/5 — Zéro *2025-04-17, version 6.3* Zéro pointé vert a rien buzz a comme app ### 1/5 — Unimpressive and buggy *2024-07-08, version 6.1.2* This app is very sparse, the UI is cumbersome, and the features are extremely buggy too. The app also freezes up a lot and often drops the connection to my Polar H10. The heart rate graph doesn’t work properly either. I even paid $2.99 for the full version, as the free version basically does nothing at all. I have an iPhone 15 Pro Max for reference. Will be requesting a refund from Apple. ### 1/5 — Poor support *2024-07-07, version 6.1.2* App is good if it works. Poor support if it doesn’t No easy explanation on how to use it. I’ve tried numerous times via email and they are not helpful. ### 1/5 — Over time *2024-06-14, version 6.1.2* Rarely works properly ### 1/5 — 日本語表示にできない *2024-04-05, version 6.1.2* 日本語表示にできないので、全然使えませんま。 ## Most praised reviews (10 highest-rated) ### 5/5 — AirPods 3 pro *2026-08-21* AirPodsы нужны 3-го поколения, вот, и тогда всё работает. Пробуйте! **Developer response:** Вы пользуетесь AirPods Pro 3? Это единственная модель, способная отслеживать частоту сердечных сокращений. ### 5/5 — First rate app *2026-08-16, version 8.0.5* I was looking for heart rate monitor to help me recuperate from heart issues. The Bluetooth reading picks up immediately and gives a solid easily viewed reading An added bonus is the calorie counter. I try and burn 500 calories on each workout. The readout is easy to use. After the workout has finished it is easy to review it and compare with previous workouts. This app has many more functions that I do not make full use of but, having read up on it I think it is really comprehensive. Would I recommend to others? Oh yes! ### 5/5 — Best app for the price, *2026-07-19, version 8.0.4* I have lost 23 pounds of fat with this app. Get this app, a cheap Amazon chest strap heart rate monitor, and you can too. ### 5/5 — Great - easy to use *2026-07-07, version 8.0.2* Does exactly what I need- track my HR during exercise. Simple and perfect ### 5/5 — Incredible tool *2026-06-17, version 8.0* The best tool I’ve found for managing zone 2 and hiit workouts. One of the few apps worth paying for. ### 5/5 — No app comes close *2026-06-11, version 7.0.2* Have been using for a few years now in partnership with iPad video exercise bike apps. Amazing. But also used to watch my heart rate to monitor HR with diabetes keto acidosis and my mother after recovering from cancer treatment. Indispensable. ### 5/5 — Clean and simple app *2026-05-10, version 7.0.2* Easy to set up with a strap and iOS, simply pair strap BLE with device then set allow Bluetooth in device app settings then pair in app. The app runs smoothly and it's easy to navigate the various app options and settings. I'm using a Bryton strap which paired easily. ### 5/5 — Super useful for guiding training *2026-05-06, version 7.0.2* The ability to graph heart rate, and compare workouts is absolutely critical to guiding your training - it tells you how well you recovered and how hard to push. It’s crazy to me that there is only one app that allows you to do this comparison. Heart Graph is awesome because if this and if you’re serious about conditioning, you absolutely need it. ### 5/5 — Use it parallel to Garmin Edge for cycling. *2026-05-04, version 7.0.2* My goal is to get 20 minutes of zone 4 cardio at least five times a week. I run this app on my Apple Watch alongside monitoring my cycling activity on a Garmin Edge. I find the Heart Graph app indispensable toward obtaining my goals. ### 5/5 — Stands the test of time *2026-04-30, version 7.0.2* Had this app pretty much since the beginning and very few apps of mine are getting used years later - but this one does. For those that like the numbers when training - this is simple, effective and detailed. No complicated multiple views of data in HealthKit - just focus on your hear rate. Only suggestion would be add a pacer to monitor a heart rate against speed to be able to see improvement. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
