Excellent timer, audible tones even when listening to music. Built several of my own workout timers, overall works well. Only downside is that recently, my timer size has started to shrink every interval until it is almost unreadable. The font size of the timer shouldn't change at all. Can't figure out how to make it stop.

Great app. Been using it for years. Also please fix this bug. For the last couple months, after some update, the app just refuses to properly close on stopping the timer and pressing back button. It sticks around the notification area and I have to always force close the app to get rid of it. (this never used to happen before and it would close on pressing back button.) Ps. I've also tried uninstalling and installing fresh from the store. It had no effect. My phone is note 8. Please fix this bug

Upgraded to Android 9 phone (Moto G7). Impetus VOLUME IS VERY LOW no matter what I set the volume levels to. Can't hear it. It used to work fine on older Android 7 phone. I think it might be bc of the Dolby Audio "feature" which I can't disable. I noticed the media volume setting jumping around while the impetus app is running. And I couldn't keep the volume on high. Please fix. Would be 5 stars otherwise. Thanks!
