Speed resets to default every time you select a chime. Can’t seem to make it run in the background while locked. If you engage the timer screen, there’s no way to back out; you have to hit start and there’s no zero time option, so a timer will start/restart. No option to buy out of ads. Doesn’t seem formatted for the iPhone X.

I was looking for something like this where instead of a pre-recorded loop of wind chime sounds, which would get annoying quickly once you get used to the loop, this is fully randomized like a real wind chime. My only complaint is that there's no volume slider and the sounds are loud even with your phone's volume turned down as low as it can go with no ability to make them quieter, which is unfortunate because I'd like to have this app playing at the same time as another app that plays sounds, but the chime sounds are somewhat overpowering.
