Can’t be used.
Brings up a box on launch which cannot be clicked off. Useless.

Excellent app
Does not work when there is protection on the sensors. Forced to remove it knowing that it is no longer reusable like the screen protection.
Oct 22, 2021
Subscription Only Now
Just a bunch of adds & subscription window pop-ups now. Couldn't ever get to the heart rate monitor. Have had app since iPhone 4s days. DELETED
Oct 21, 2021
Annoying ads
Everything leads to the $59 subscription. The big ad covers the entire screen even if the heart rate is being measured so you can't see the results. If you tap the continue, it pushes you over to more ads. It really isn't designed to be free.

Bad …

Used to be good then they cashed in
Used to be good then they cashed in. Can't measure for free anymore. Pop ups blocking things constantly

Deleted this app
I've used this app for a few years, and it was excellent. Until today when I tried to use it. You have to pay now for more than a few free measurements. Why? Who knows. They lost a long time user, will look for another similar service. Read the reviews, developers. This is what greed gets you. Why this app has 4.9 stars is beyond me. Why can't you have an ad supported version at least? $59 for a heart rate monitor that I question the accuracy to begin with? Nah.

Useless without creating an account
The app description suggests that registering is required to export results, but this isn't the case - instead, after the first time you use it, the app shuts down and stops working entirely until you create an account.

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!
