SelfTimer is a timed shutter release for your Windows Phone. The good thing about SelfTimer is that it is a feature many want for their Windows Phone camera to allow them to hop into the picture. The bad thing about SelfTimer is that it appears to be a Mango app.
Dan has been able to install and use Selftimer on his Mangofied Samsung Focus but it's not showing up on my Nodo Focus. The good news is that it's working as advertised on the Dan's Focus.
If you're running Mango on your Windows Phone and want to give Selftimer a try, there is a free trial version available and the full version runs $.99. You can download either here (opens Zune) at the Marketplace. I was not able to find the app from the phone's Marketplace app.
If you are able to get Selftimer up and running on your Windows Phone, let us know your impressions in the comments. Now we just need a decent tripod for our Windows Phone.
