Where Challenges Alarm Clock is better
- Forcing you out of bed. A picture challenge sends you to the object you chose; a QR or barcode sequence sends you round the house.
- No easy way out. Optional locks stop you closing the app or turning the phone off while it rings, and snooze can be limited or switched off.
- Track record. Over a million downloads and tens of thousands of reviews on Google Play.
Where LFG Alarm is better
- Waking more than one person. One alarm, one link, and every phone that joined rings at the same moment: your partner before the 3pm pickup, flatmates on the same 7:00, a whole group before a party.
- Friends who can see if you got up. The wake board shows who got up first, who snoozed and who slept in.
- Moments without a set time. Rocco, LFG's agent, watches the web and rings you when an account posts, a stream goes live, a token hits your number, or your own script calls the alarm's link.
- Every phone and the browser. iPhone, Android and the web, so a shared alarm works whatever phone your people have.
Which one should you get?
- Choose Challenges Alarm Clock if you are on Android and your problem is switching off the alarm half asleep.
- Choose LFG Alarm if you want a friend on your alarm who sees whether you got up, if you are on iPhone, or if you want alarms for things that happen online.
