My wife needed a presentation timer for an event, to replace pieces of paper with numbers on them to show the speakers how much time they have left.
I thought, ok, the standard iOS timer should do the trick, and if not, there must be tons of apps like that.
Sure enough, there are apps, but none of them were simple or clear enough. Some had too small numbers to be visible meters away, some funny color schemes, some funny graphics, some counted the wrong way. Even the best ones had seconds ticking away - my wife asked "why would the speakers need to see the seconds?", and I had to admit that she was quite right, even the seconds are surplus to requirements here.
So in the end I took out Pythonista and spent 15 minutes writing an app of under 100 lines that just shows the minutes, with an unobtrusive black bar at the bottom of the screen showing the seconds ticking away, mainly so that the user knows that something is happening, and a starting time that is adjustable by sliding a finger up or down on the screen. Accessible via home screen shortcut, it was simple enough and served its purpose at a large event.
The main thing I wanted to say here is "yay Pythonista!" - once again.
Here's a gist for the code. Note that it needs the beta at the moment.
How do you exit when running from Pythonista?
@agalli, swipe down with two fingers (standard gesture when running UI apps in full-screen mode).
And oh yes, now it works in the App Store version as well.
