Perfect for its purpose!
The ability to EASILY customize multiple complex interval timers, to include the sounds, names of sets and the tracking ability are the foundation for this great workout timer.
The seamless interface with iOS on my iPhone and iPads compliments the basic features. I can listen to playlists through the app or on the iPhones native music player, switch back and forth between apps and this one doesnt lose its place, and the app hasnt crashed once on me yet (knock on wood). Great app and absolutely worth paying for pro, if for no other reason than to supports the devs who wrote this excellent timer. Thumbs up!
