Very basic, which I like. A little confusing to get the hang of, but "how to use" got me there.

this app simply does not work. it does not start, countdown or sound an alarm. in fact it does nothing.

Never miss an important event again with this intuitive scheduling app. Set alarms and reminders quickly with simple gestures, keeping your plans organized in one place. Avoid the embarrassment of forgotten appointments and ensure you're always on time.
