As all other mobile or PC applications also Locus Map needs testing and feedback before releasing a new version with new functions and features. Therefore there are so called Beta versions pre-released on which these new functions and features are tested by developers and helpful users as well. These Beta versions are public and they are free.
Locus Map Free Beta version is almost fully functional as the Locus Map Pro version (except track recording widget) for a limited time period (see comparison of the two versions >>). It obviously contains also functions and features that cannot be found in previous versions of the app and, if the testing proves false, will not be found there in future. In rare cases it can contain bugs or be unstable.
Locus Map Free Beta version replaces your own installed Locus Map Free. No data (maps, tracks, points etc.) are lost. It does not influence Locus Map Pro - both applications can be installed simultaneously on the same device. However - they share the same data - maps, tracks, points etc.
