Unlike my past applications, Graphie came out as a paid application, but for $1.49 and, as always, completely without ads.
When you purchase Graphie, in Google Play, it will be assigned to your Google account. If you use the same Google account on a new or factory reset device, you will have access to all previous purchases.
To change the metadata of images in the Android OS, an external tool called “ExifTool” is used. At the moment, it does not support changing other image formats, but this may change in the future.
This was done intentionally to fully support Android 10 (and in the future Android 11). I am working on finding a solution to enable this feature.
