Barely works – Runtastic Heart Rate PRO Review

this app only works sometimes and i am a teenager with a heart condition, and keeping up with my heart rate is a big thing for me. i paid for the pro version to get more readings, but it doesn't even work. it works 2 out of every 10 times which is very inconvenient. do not recommend this, waste of money.
