TemperTimer Free has been submitted to the App Store for review. Hopefully all going well, it should be available for download in a week or two. It is iAD supported, hopefully I have implemented this is a non-intrusive way as to not effect the application functionality.
TemperTimer is currently undergoing some changes and should hit the App Store in a few weeks. As for a feature list, I may publish that closer to the release date, however one thing is for sure it will still be simple to use.
