Here's to another app I've been willing to write for a while: a short notification. The idea is dead simple:
Type a small text and push "send" on your phone. The text appears as a notification that you can read with one swipe of a finger, when your phone is locked, directly from the notification center!
Perfect for very short notifications of things you have to remember for a very short amount of time. The app can be downloaded directly from the Windows Phone App Store and sells for 0,99€ ($US 0.99).
Let me know if you'd like some other features (saving all the messages sent maybe?) and don't hesitate to review the app in the store (specially if you have many stars to give out ;) )! Thanks!
