Used to set a backup just in case, but this alarm works well. Generally find I wake up feeling more awake than usual, so I think it is working. Update: stopped working at all. Not sure if it is due to a system update. It looks like it is working, but no alarm goes off. (I watched it blow right through the set time.) I am really disappointed because I liked this app a lot when it was working.

After years of using this, it's time to uninstall. What was once a great app just doesn't work anymore. No tracking, no alarm, nothing... it's dead Jim. Criticisms: Wonderful app but common recurring bugs such as crashing when switching between menus, or having to exit & close the app completely after deleting an item before it registers, can make it a hassle to use. Suggestions: would like to be able to add own alarm ringtones and music, would also appreciate a larger viewing pane for notes.

It crashes during the night half the time. The UI is slow, heavy, and difficult to use. Sometimes the tracking button is unresponsive and I have to force close the app. There are hardly any settings for the alarm or tracking. You can only have exactly one alarm; you can't disable the alarm, or add another one, or set it past 12:59. Constant full screen ads and premium nag screens. Don't use this; it's an exercise in frustration.
