NOTE: Works best on iPhone 4/4S/5/5S/6/6S/7/7+ because it has flash. On iPhone 3GS and iPod touch the app has to be used in good lighting.

NOTE: Make sure that your fingertip completely covers the camera lens. Press gently, since pressing too hard reduces blood flow in your finger and it's harder to get a result. Make sure that your fingers are not cold. This app is for recreational and fitness use only!

Good app

I have a problem with my heart rate being fast so I looked for an easy to use app and tried this one. It’s easy to take your pulse. I found if I try to take my pulse with the phone in a hard wallet type case it often didn’t detect my pulse because you can’t get your finger close enough to the camera on the back. I have to take my phone out of the case to get a good read. The other thing I don’t like is the subscription price for the full app. I’d rather try it free then pay say $10-$15 for the full app. The subscription is way too expensive. Display of old reads should be easier as well. Just a drop down menu would be helpful. Maybe that’s on the full app? I’ll never know because it’s too expensive to subscribe.

Saved my life

I had a problem waking up during sleep time. My GP thought it was asthma but got it wrong. She mentored I had a low heat rate but she thought that was normal because I was pretty fit and healthy,
One night I woke up severely short of breath I remembered what she said and downloaded this app
My heart rate was 30BPM I immediately contacted my GP and a friends cardiologist and after an angiogram I ended up with a pacemaker which fixed the problem. 10 stars for this app tbh :-)

Mostly good.

Unless these are limitations only for the free version, the following ought to be considered.
1. The app appears to freeze the clock on my iPhone. This is annoying when wanting to measure directly after a workout and then 2 minutes post workout. Currently I have to exit the app to ‘resume’ the clock. Maybe it’s just me.
2. It would be nice to be able to edit tag names. For instance, I created a tag which noticed had a spelling mistake. I annoys me that I can’t simply edit the tag name.
3. As the app has been updated, it has become less sensitive to detecting my heart beat. Is it the iOS or the app at fault here?
Overall the app is good but I have a preference for outright purchase as opposed to subscriptions.
