This app behaves exactly like 'PrivateText' but it is enriched to fulfill an additional goal.

The app has been equipped with a completely hidden activity that allows you, the owner of the smartphone, to detect and archive each physical movement of the device and each screen-on/screen-off event, by collecting the respective date-time of the events (motion is represented by start-moving and end-moving events), letting, indeed, you quantify the frequency and the duration of each period of time in which a possible unsolicited attention to your smartphone is occurring.

The app, beyond the possibility to explore all the logs archived, allows to rely on the exportation of the entire set of logs in a form of a unified log file, whether the needs to communicate with the authorities occurred.

YourFriend is available only for the Android platform and is freely available on Google Play.

Then, just like PrivateText it presents the same enhancement to the (premium) level of use, in the form of an in-app purchase product, for the exportation as a unique text file of the whole content written by the user.

Look at the user guide for the details.
