Nice, but missing something.
This sand timer looks great, and I really like the method of flipping your phone to flip the timer. However it fails to simulate a real sand timer in that when you flip it, it resets to the full time. If you flip an actual 3-minute sand timer with 30 seconds left before it runs out, that 30 seconds worth of sand will now be in the bottom, so you now only have 2:30 remaining before it’s done. This concept should at least be an option in the app. To be fair, none of the other sand timer apps I looked at seem to have it either. So it would make yours stand out! Deleted for now, but I’ll check back from time to time (so to speak) and if this feature is implemented I’ll download again.
