Here is the Object Counter By Camera App. You can count things with this counting app via the camera in a shot.

Count objects automatically and counts things from photos

The object counter determines the number of objects crossing an area monitored by a camera. Objects crossing the protected area are counted automatically, so this process no longer depends on how tired or inadvertent the operator is. A number of objects detected by a camera in one or more zones can be indicated in a video display.

Take a photo of things you want to count, highlight one of the items – and get the result.

It can be used to count people, as an inventory counting tool, as industrial step counting, workouts, sports scores, or a myriad of other use cases, such as a visitor counter, vehicle counter material/product counter, etc...

Object Counter By Camera App will count literally anything you show it
