Negative stars if it was up to me. This may be a google clock but it's even worse than Google maps on some androids. It doesn't work and I think it's just an app to put on your phone for decorations to make you think you have an alarm clock but you really don't. It's never ever once gone off and I woke up late every time. Almost was late for work several times. Maybe this works better on certain androids or iphones? Bt don't count on it. Btw I have the Moto G Stylus with Android 11 update.
