PRO vs. FREE Version

The free version of the app requires an internet connection. Once online, advertisements will show on the upper part of the screen. If you go offline, many of the features will not work.

If you want to have all of the benefits and features of the app, we recommend buying the PRO version. For a glimpse of what the app can offer, refer to the following table to see the distinctions between the free and PRO versions.
