Hi Ish,
Great timer. I have a few points of feedback which (hopefully) you'll find useful:
1) The timer screen is a bit cluttered. The "Hr:Min:Sec.Cs" label isn't
really necessary, is it? Maybe it should be an option in settings?
2) Is it always necessary to display hours and minutes? I'm pretty sure this is standard practice, but again just displaying eg. mm:ss.cs would reduce clutter for 3x3. Another option for settings?
3) 'Start' button is nice and big, but still missable! I just did an Ao50 and missed it a few times. Is there a reason why you're using a button, rather than just touching the screen? Can the whole timer screen be the start/stop button?
4) The background colour is... er... ... but this has been mentioned previously!
5) Popups when you hit a PB are nice, but have to be dismissed with a 'back' key press. Would be nice if touching anywhere dismissed these.
6) Popup when you hit Ao5/12 might be nice?
7) No way of +2 or DNFing a solve. These options only need to be visible after stopping the timer.
8) Would be nice to have multiple sessions, and for the progress graph to show the progress between the sessions, rather than for individual solves. My graph is all over the shop, as my times fluctuated between 17 and 28 seconds

(). If today's Ao50 was session 1, with an average of 21.67, tomorrow's was session 2, with an average of 22.xx, next session average 20.blah... this would be a far more meaningful graph than individual solves?
9) X axis intervals on the progress graph have a decimal place, although they integers (number of solves)?!
10) Would be nice to have a 'Timer' button directly on the splash screen, rather than having to go > Menu > Timer.
11) Would be nice if settings tab on the Timer screen could be activated by menu-button press? In fact, is this required as its own tab at all?
Other than that, it's great. These are all really just suggestions, there's no 'problems' with it. My main droid timer is still JJtimer, just because it allows me to have separate sessions, touch anywhere starts/stops, etc.. I'd recommend taking a look at it, if you haven't already, and seeing if there's any good ideas you can incorporate? I will be watching this space as, with a little work, this could be awesome.
Well done, and thanks again!
