Sleep Cycle heart rate App Reviews

Very accurate! Tested against heart rate monitor in ER where I work.

Does what is expected and very easy to use. The results appear pretty accurate!

Very accurate recommend for everybody

Easy, intuitive, fun - works well with health app.

Doesnt scan your finger, doesnt work: waste of money

I tried many heart rate monitor apps on an iPhone 6 Plus. Most of them failed completely while some worked once in every five or six attempts. I think it has to do with the protruding camera lens (due to the image stabilizer) and the large spacing between the flash and the lens in the iPhone 6 Plus. This app is the ONLY one that worked consistently and was accurate when checked with several manual measurements of my pulse. Yet it is nowhere in search! Why, Apple? This app should be the first result on a search for "heart rate monitor". Yes it isnt free but the free apps do NOT work. Here are some of the apps that failed: Instant Heart Rate by Azumio - a complete fail; did not work even once Cardiio Heart Monitor - only worked using their face mode, which is inaccurate; finger mode never worked Runtastic Heart Rate Monitor - worked intermittently; perhaps once in every five or six attempts

On iPhone 6 with Apple case, works well, and pushes data into HealthKit. Lets you tag each reading with your activity at the time, and has historical graphs for each activity. Very handy.

I was ready to go spend money on a wrist band monitor but this works just as well. This developer puts out quality apps. Very impressed.

Initially had some difficulty reading pulse. After a few updates is working very well. Measured against blood pressure monitor and is Now very accurate.

Like the graph functionality, grouped by note associated with the heart rate. Very useful

I use it every day multiple times. Easy and accurate.

You need to press quite hard. Took me a while to figure out how to get it to read properly.

Its very good but you should link and share with Health app which is come with originally iPhones, then I will bring you 5 stars.

The app used to be quite bad for its price, however after an update its a lot better. Heart rate detection and accuracy has much improved. It also supports Health App. Now it is not only the best looking heart rate monitor in the App Store, but also the best performing one.

This app doesnt work on iPhone 4S. Please, fix it

Add support of the health kit please, ios 8.1

You have to do something with your algorithms. It takes almost two minutes to measure heart rate. I could see the pulse on the apps screen by myself, but the app easily couldnt count it.

Sorry to say that it doesnt work - spend quite a few minutes placing my finger here and there, but have only seen some blurry redish picture. Happy to provide more details to developers, but havent found any appropriate buttons to report this.

Good stable heart rate detection in new version and thanks for health integration.

This is a very convenient application for estimating the heart rate. It has tags to mark the measurements, like before and after workout, which works great for me.
