Good questions and answers

Can I use my Apple Watch for measuring heart rate?

Yes. Paul recently found that this is possible as long as an exercise is started in the work-out app. Thanks Paul! 

Will LAPP become available for Android?


Possibly, but it will take a while. We learned that the quality of the sensors differs greatly among Android smartphones. Many smartphones simply cannot generate data of good enough quality for LAPP to accurately derive the trainings details.
