Skimmer supports the current Skimmer Pro mobile app version plus the three previous minor releases. Older versions of the mobile app may continue to work but will not receive new features, bug fixes, or guaranteed access to server features.
Current version support
Skimmer supports Skimmer Pro 12.16 and later. If your app is older than 12.16, you can’t sign in or sync until you update it.
How to check your app version
As an admin: Go to Settings > Users to see the list of your techs along with the app version each one is on.
On a tech's phone: Open the Skimmer app, tap Settings, and check the version number at the bottom of the screen.
Next steps
Have your techs update to a supported version via the App Store or Google Play.
