Instant Heart Rate
- Gives an accurate heart rate
- It is user friendly because it gives you directions on how to use the app, so it's not complicated.
- It is a free app that works accurately
- It doesn't share any personal data
- The app is slow when calculating your heart rate
- If there is something minor on your finger like a crumb, or marker, the app will not be able to calculate your heart rate
- It can only be used on smart phones
- Has a few pop up ads, which does get in the way sometimes
I would rate this app a 4/5. This app is accurate for its purposes, but the ads do get in the way when calculating.
