627.AM is a nifty daily assistant that includes a wake-up alarm, daily weather forecasts, and notes. While the free, ad-supported version is still Windows Phone 7.x compatible, the paid version of 627.AM was recently updated to Windows Phone 8.
The version 1.6 update for the paid version of 627.AM adds fast app resume support, a few bug fixes, resolution support for 720 HD screens and live tile support.
The live tile support offers the multiple sized tiles and the tiles now show alarm time correctly for the various regions. The wide tile displays the alarm, current temperature and a count of your notes.
There isn't a trial version for the Windows Phone 8 version of 627.AM and it is currently running $1.49. The free version of 627.AM is compatible with both Windows Phone 7.x and 8 devices. The free version is ad supported and will give you a good feel for things if you're on the fence.
