Pretty good app

I’ve been using this app for the better part of a year, and it’s pretty good. Would easily be 5 stars with two simple fixes:

1. It has started crashing lately. I’m sure this is due to recent iPhone updates and it just needs a new patch to be written. Hopefully this comes soon!

2. For some inexplicable reason, the app will not work unless it is open on your phone. As in, your phone must have the app open on the screen at all times. Want to change a song while developing? Sorry, can’t do that. Want to lock your phone? Nope, can’t do that either. The countdown will stop. The only time this is really an issue for me is if I am tray developing and want to turn my phone screen off so there isn’t any light in the room.

Fix this and it’s 5 stars easily.

Developer Response ,

1. Yep, due to recent updates and frustrating at this end. New version on the way in 2-3 weeks.
2. New version works in the background!
3. Drop me a line if you want to test the new version.
Thanks, Todd!
