Can't thank enough for this app - only necessary functions, intuitive, reliable! There's just one minor glitch - when editing text, it tends to select a word or two instead of moving the cursor to a desired position. It's maybe just my phone though, no biggie.

This app is basic - which is great. It allows me to define multiple workouts with work and rest periods including repeating groups of work and rest. There are no fripperies which distract from or interfere with its primary function. Backup and restore ensure that my routines are preserved. Brilliant.
