Over the holidays I wrote Divers Alarums, an Android alarm clock app. It’s a solve-my-own-problems type app with a fairly basic feature set: it fades in the alarm over a period of time (this is why I wrote it), supports multiple alarms, lets you set alarms for specific days of the week, has a snooze feature, displays a notification, and is reasonably clean-looking and free of obnoxious ads (by which I mean it has no ads).
