Wakie is an alarm clock app with a difference. Instead of waking up to some custom sound effect or audio file, you're called by another Wakie user, who then chats, sings songs, ask you questions, or otherwise gets your day off to a more interesting start.

If this idea makes you a little uncomfortable, then you're not alone, but Wakie does include some safeguards. In particular, phone calls are automatically cut off after a few minutes (with a 10 second warning), so there's no time for your chat to get awkward. The person calling has no idea who you are, as phone numbers are never exchanged. And the developer says the app "learns" who you like to connect with, so presumably will match you with your preferred gender/ age range, most of the time.

There's also now an option to rate your wakeup calls, which should help to highlight anyone who's abusing the system (or the called).

Alternatively, if you don't need to receive a call, you can volunteer to make one yourself. Just click "Wake Someone Up" and you'll be sent push notifications whenever someone needs a call. (You'll need an internet connection to wake someone up, although not to be woken, as you'll receive a regular phone call.)

As the system relies on other people calling you, your call times won't be very precise: the official FAQ says they could be plus or minus five minutes from your requested wakeup time.

But the good news is that, if there's no-one around to make your call, Wakie does have an automated system which steps in, makes the connection and plays you a pre-recorded message.

What's New in Version 2.5.5

Hey Wakians,

This new version is much faster to load and work – try it out!
Also, it shows the connection quality during the call.
If you send an emoji, it will be much bigger then when in text message now – we love emojis!
Now, the app supports Force Touch: create a topic with a long tap from your home screen, preview the topic right in the feed, reply messages right from the push notifications etc.

And finally, we have added some new country flags, including... Greenland! Gosh, it must be cold there!

There's no telling what sort of call you're going to get with Wakie, and that's probably the point. If you want complete safety then stick to your phone's built-in alarm app; but if you're happy to gamble with a random caller - who, even if they turn out to be an idiot, will still at least wake you up - then this is certainly a more interesting way to start your day.
