I’m enjoying using this. this app exceeded my expectation. Could get 5 stars with some minor improvements. Priority order
* please add the ability for user to type notes about each session.
* please add, if possible, a count-down timer for when the app is “warmed up” it’s currently just ready in about a minute.
* Please add the ability to export data in CSV. This data could just be files that can be accessed via file sharing on iTunes.

CSV needed

The ability to see and download the data im csv form would easily push this to a 5 star

Product seems amazing. I would like some comparisons to lab tested equipment. The app works well. I think it needs heart rate and zone calculations so you can compare heart rate to other data on same charts. This could be a big part of many athletes training program.
