Version 2.2 is available!
This version introduces a new ramp interval: this kind of segment lets you specify a start and end value (either power, FTP% or grade). This is perfectly suited for smooth warm up or cooldown but can also be used anywhere in trainings.
Version 2.2 also contains several bug fixes, in particular it solves the issue with Strava not displaying the time correctly.
Feedback welcome, enjoy, get stronger!
