Setting HR zones (Android)

[pdrawmer]

A suggestion.
In the current version, setting HR zones is a pain.
1) It's difficult to amend entries as the entry box is at the extreme of the screen edge, and using a touch screen is difficult. Please move the data entry points off the screen edge.

2) There should be no need to enter the upper and lower limits of each zone. You should be able to set up the 5 zones by just asking for the lower limit of each zones 2-5, and obviously the higher limit of each zone is the limit of the one above minus1. (or the upper limits of zones 1-4 etc)

3) make a single save for all the zones, not each one. Do the range check at this stage, not for every zone.

This would make zone setting much easier.
