The SmartBroom iOS app saves each sweep as a separate .csv file in your iCloud Drive. You can view your files either in the SmartBroom app or the Files app.
In the SmartBroom app, navigate to the ‘Review’ tab and tap ‘Open Sweep File’
The Files app is a system app from Apple, which can be accessed from your Home Screen, App Library, or by Spotlight search
In either case, you will be presented with a standard Apple Files interface.
From the main Browse tab, select iCloud Drive
Scroll down and select the SmartBroom folder
Sweeps are stored in sub-folders by date, and further sub-folders by sweeper name
Because the sweeps are stored in your iCloud Drive, if you have a Mac or PC signed into the same Apple Account, they will automatically sync to those devices as well.
