If you're like me you get your twitter updates on the go via SMS, but you have to pay to send SMS back to twitter. You might even be slightly bitter about this. So all you want in a web app is an update field, and perhaps a counter of remaining characters, one that if the update fails won't lose your text.

Get JustUpdate from the AppStore.

Provided free of charge, so do what you want with it, just don't blame me when you accidentally cause a meltdown of a nuclear reactor. Please. Any questions, complaints, death threats, just contact me.

The source code is available on github.
