Okay-- readings often time out and won't save – Runtastic Heart Rate PRO Review

This app is okay for recording my heart rate it keeps good records that you can sort by whatever filters they have (personally I don't categorize the readings bc I only use it for one specific thing) but the one complaint I have is that it will frequently stop the reading right at the end and not save it and take you to the "how to use" screen. I know how to use it-- so it drives me crazy sometimes I'll have to keep trying for like 20 minutes to get it to save! Idk if other people have this issue or if it's just me; I should have read the reviews before I bought it but it was like $2 or $3 for unlimited saved readings so I spent the money and would say it's worth it for what I need it for.
