Nice, but missing something.
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.
