Because AppBrain tracks all apps on Google Play in regular intervals, we're able to provide
you with a detailed timeline of what actions Matthias Klass took on Google Play.
The timeline below shows when Matthias Klass developed and launched a new Android app or game,
and every update to their apps.
In addition, we track when an app gets unpublished from Google Play. AppBrain also tracks when
an app becomes popular and reaches a higher level of downloads.
This timeline makes it easy for you to quickly spot when a developer became successful, when
they did the most Android app development. We hope it will help you in understanding the
story behind the success, and it may also allow you to estimate how important metrics
like the monthly active users, revenue and income have potentially developed over time.
