About this app
Timer Machine is an interval timer you build yourself: a warm-up, eight rounds of thirty seconds with rests between them, then a cool-down. Good for HIIT and gym sessions, running, stretching, yoga, and just as good for study blocks, daily routines or a presentation.
Every stage can remind you how you want: a sound from your own music, a spoken phrase read out by the phone, a vibration pattern, a beep, a halfway warning or a full-screen notification. Timers keep running in the background and show progress in a notification, you can float one over other apps in picture-in-picture, put a shortcut on your home screen, run several at once, schedule one for a set time or repeat it weekly, and back the whole lot up.
This is the build made for stores outside Google Play. It leaves out the in-app purchases and the Google services the Play version uses, so a few extras from that version are missing and your backups are files you save yourself rather than copies kept in the cloud.
