FoCal Mobile brings Reikan FoCal's DSLR camera calibration and analysis tools to your iPhone. Connect your camera to your device to analyze autofocus performance and tune it for better shots. The free app offers automatic control for Canon and Nikon DSLRs and Mirrorless cameras supporting AF tuning, one-tap testing of autofocus performance, camera time synchronization, and more.

With a FoCal Pro subscription or FoCal Pro (Desktop) license, you can calibrate your lenses, compare performance data with other users, export data to FoCal Pro Desktop, and synchronize camera time with one tap. FoCal requires a FoCal Target for calibration and a FoCal account for access to all Mobile Pro features.
