Thanks for the suggestions!
A filed with Cadence and target cadence (actually you can have cadence or target)
You can actually tap on the Cadence Data Field and it will start cycling between different value. One of them show the current Cadence + the target cadence next to it. Other switchable fields are: Power, Target, Heart Rate, Power Lap.
Ability to increase/decreas power only for interval or for all workout (like in ictrainer)
You can inc/dec power for the whole workout by changing your FTP in settings. The change will take effect immediately and will re-calculate the workout on the fly. The original FTP value will e restored automatically next time you sync a planned workout from Intervals.icu.
You can change the Power Target of the current intervals by using the +/- buttons.
A popup or anything to see next intervals power & cadence target. (in IcTrainer, I have a popup 5s before next interval)
At the moment I am not planning on adding this feature, but you can switch on the audio signals in Settings, and also the workout graph should show target if you hover on an interval (although that’s more usable on Desktop).
