I have downloaded the app last week, it worked. I tried to start it today an error message after the initial "howto save battery" message pops up and says "Sorry this version (0.1) of the app is too old! Please check for your options: http://247timeleapse.com"
When I click OK the app closes.
In play store no new version is available.
I am using a Nexus S (i9023), Android 4.1.1 (JRO03E)
