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) ### 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 ### 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!!! ### 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! ### 2/5 — Жаль *2025-07-30, version 1.0.7* Перестало находить мой пульсометр ### 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. ## Frequently asked questions about Heartool ### What does Heartool do?
