The SteckerChecker app is no longer under development. The SteckerChecker update of October 22, 2014 was the last update of the app and there will be no further versions. On 31.12.2014 the app will be removed from the Google Play Store and ITunes App Store. A new download and installation will no longer be possible from this date.
Apps that have already been installed will retain their functionality, with the exception of Remote Access, and can continue to be used.
The successor to the "SteckerChecker" app is the "SteckerPRO" app, which is available in the Google Play Store and ITunes App Store.
