Fantastic. Recently switched from iPhone and this is better than anything available on the Apple App Store. My only wish would be louder, more noticeable alarms to notify you when it's time for the next set. Difficult to hear them while music is playing thru my headphones.

Getting slower and slower with each release. Recording a set, and moving between sets feels sluggish, takes >1sec now. Bleh.

Seems very versatile indeed. Initial loaded workouts and exercises a bit thin but don't be put off. You can edit everything, add anything. Update: used this for a bit now and it has all I need. You can add per exercise notes and workout notes. You can add any type of exercises you do. Works for me. Wish you could set the times on the countdowns and run concurrent timers but that's about it.
