The graph works but not the lower % table. ### 3/5 — La aplicación no es como la imagen. *2025-12-27, version 2.0.3* La aplicación no es como las imágenes, solo rastrea frecuencia cardiaca, pasos y frecuencia en reposo. Se está rastreando con HW 9 coospo. También no te guardan los pasos que llevas en el día, los pierdes si lo apagas y lo vuelves a conectar ò si pierdes conexión bluetooth. Esperemos un actualización ò que dispositivo es para que rastreen todo, ( FR, FRV, TEMP. Oxígeno en sangre,etc.) Le doy 3 estrellas, por casi, ir exactamente medición con la del pecho, ( aunque creo que el brazalete y no la app) ### 2/5 — Жаль *2025-07-30, version 1.0.7* Перестало находить мой пульсометр ### 3/5 — Too basic and hard to understand *2025-03-16, version 1.0.7* I downloaded to connect with my COOSPO arm HR band. I was able to set my own heart rate settings but nothing else. When I open the app it says it is not connected. The HR shows up on my Apple Health (on my iPhone) but I can’t see how much time I spend in each zone. I was hoping this HR band would show much more HR data and be able to display it through this app. It’s extremely basic. ### 1/5 — L app non va più *2024-09-17, version 1.0.7* Come mai che da un paio di settimane l app non va più? Da sempre error network quando voglio terminare una registrazione ### 1/5 — No funciona la app *2024-09-16, version 1.0.7* Lleva por lo menos 2 semanas que no puedo acceder a la app ### 1/5 — L’app ha smesso di funzionare *2024-09-16, version 1.0.7* Era top, ma da giorni da un errore (network error) e non va più ### 2/5 — Network Error *2024-09-15, version 1.0.7* Used the app for two weeks and thought it was good then “Network Error” notification came up and now I can’t log in, deleted and reloaded, gets the same error. It has been a week now and I’m trying to find a replacement. Also, it’s strange to me how this app’s readings don’t match the Coospo app for the bike computer. ### 1/5 — No longer works *2024-09-14, version 1.0.7* This app does not appear to be supported any longer. It shows “Network Error” when trying to login and record or view data. Everything is lost. ### 2/5 — Was working good *2024-09-14, version 1.0.7* Was working good and I really liked it, but now keeps saying network error and doesn’t work ### 1/5 — Falta de funcionamiento *2024-09-14, version 1.0.7* Después de un mes de uso me da error constantemente y me h borrado todas ls actividades grabadas ### 2/5 — Network error *2024-09-14, version 1.0.7* Network error ไม่มามารถบันทึกข้อมูลประวัติ hrได้ ### 1/5 — Network error *2024-09-14, version 1.0.7* This app is unusable due to network errors. Please fix this. ### 1/5 — app non funziona *2024-09-13, version 1.0.7* l’’app non registra le attività ed il server non risponde ### 1/5 — Network error *2024-09-13, version 1.0.7* Просто перестало запускаться.. очень жаль, было просто и удобно, аналога такого не нашел…( ### 3/5 — Typically works *2024-09-13, version 1.0.7* Every once in awhile I get a network error notification and it won’t save workout and you have to close the app. Currently been happening for two days. I count calories so it’s annoying. Also way over calculates calories burned. I enter my numbers into a web page to get real numbers ## Most critical reviews (10 lowest-rated) ### 1/5 — แย่ *2025-12-14, version 2.0.3* ข้อมูลอื่นๆ หายไป วัดได้แค่ HR ### 1/5 — Por qué no es compatible con IPad? *2025-11-29, version 2.0.0* Tengo un IPad Air M3 y no he podido instalar la aplicación En mi dispositivo pero en mi iPhone sí que alguien me ayude! Gracias ### 1/5 — Опять сломали *2025-10-30, version 2.0.0* Неправильно отображает статистику зон пульса после завершения тренировки - 100% в зоне максимального пульса. ### 1/5 — 使えない *2025-10-04, version 2.0.0* 起動してもすぐ落ちるから全く使えない 酷すぎるにも程がある ### 1/5 — Very annoying *2025-05-30, version 1.0.7* Pretty much any time my training data can’t be stored because the login is expired, even if my historical data is displayed when I start the app (which I guess would indicate that I am successfully logged in). Please modify the app to check during app start if the user is logged in properly or allow a re-login without loosing my training data. The app is useless for me if I can’t store my training data (loosing any historical info) Note: there are sometimes several weeks when I use the app again. ### 1/5 — No funciona *2025-04-26, version 1.0.7* Me hace introducir de nuevo la contraseña, no la válida y si intento resetear con el olvido de contraseña, es imposible ya que pide un código que no te llega nunca ### 1/5 — Waste of money *2025-04-25, version 1.0.7* Unable to connect to app. Waste of time and money. ### 1/5 — No funciona *2025-04-03, version 1.0.7* No detecta el sensor de pulso. ### 1/5 — Non funziona!!!! *2024-09-24, version 1.0.7* All’impresa l’app non funziona più! Impossibile accedere, ho provato in tutti i modi. SCONSIGLIATISSIMA!!! ### 1/5 — App is not working *2024-09-18, version 1.0.7* Keep showing Network error all the time ## Most praised reviews (10 highest-rated) ### 5/5 — RockBros seamless sync! *2025-10-01, version 2.0.0* Just use this for the chest heart rate monitor. It works well. Very well!!! ### 5/5 — Gute App *2025-07-08, version 1.0.7* Macht was sie soll und funktioniert einwandfrei mit meinem Coospo H6M Pulsgurt. Hilft mir enorm beim Laufbandtraining um im moderaten Pulsbereich zu bleiben. Automatischer Export an Apple Health funktioniert auch ohne Probleme. Scheint die Pulsrate auch über IPhone an die Apple Watch zu senden, die diese dann wiederum in der Trainjng App anzeigt. Ich mag die Heartool App. ### 5/5 — Goood *2025-05-02, version 1.0.7* Good ### 5/5 — Ver. 1.0.6 *2023-10-11, version 1.0.6* Salve, questa versione non registra più le attività. Uso con devics coospo hw807. Prima dell’aggiornamento andava bene. In possesso un iPhone 13 pro. Ver.17.0.3 Metto 5 stelle perché fa quello per cui è stata ideara. ### 5/5 — Хорошее приложение *2023-09-02, version 1.0.5* Простое и понятное приложение. Можно подключить внешний пульсометр, есть звуковое уведомление о превышении максимально заданного пульса. ### 5/5 — Perfect for HIIT on Treadmill *2023-04-30, version 1.0.4* I downloaded this app to work with the Coospo heart rate monitor. It does exactly what I need for HIIT training on the treadmill. It has a nice display of BPM, heart rate zone (percentage) and calories burned, along with a live color-coded chart based on heart rate zone. It also gives a max heart rate warning - the monitor vibrates and a big alert comes up. It keeps a record of your workouts as well. It also has other useful options for analysis. I’ve focused on the live training ones. Very satisfied. ### 5/5 — Works Well *2023-02-15, version 1.0.4* Exactly what I was looking for. Simple, accurate and useful. ### 5/5 — Great *2023-01-28, version 1.0.4* Use this every day… great app ### 5/5 — Soddisfatto *2022-08-15, version 1.0.4* App completamente gratis che fa quello che deve. Legge molto bene i dati della fascia cardio durante il workout e se abilitata li trasmette all’app salute. Quello che cercavo!! ### 4/5 — Can’t work out how to adjust maximum heart rate *2025-07-31, version 1.0.7* I just tried this app out today & it worked really well! The only issue I have is not being able edit the maximum heart rate. I think this is set at 180 but I want to adjust it to reflect my age - please help! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
