Thank you!
I appreciate that the user can enter their own terms for the habit and duration, compared to another low-frills, low-telemetry app Onrise (also good and I really appreciate developers who put their work out with such a low barrier to entry. If I make software, I will give it away, too- the potential for good is huge). Maybe this is a bug- tapping the gear icon, then tapping Close without changing anything, removes the entry fields and pushes the three buttons (Save, Close, Remove habit) to the top of the screen, with no apparent way to get back other than rebooting the app (the buttons are unresponsive). iPhone xR
