For all you cell-counters out there, the MiCellCount app by Scientific Device Laboratory may be a useful addition to your lab-app repertoire. The app allows users to import a photo of cells from their camera roll (or users can take a photo directly from within the app). Users can subsequently use the gridded image to count cells simply by tapping on individual squares of the grid. Individual counters corresponding to each square increase by one each time you tap; additionally, a cumulative counter appears at the bottom of the screen. You can change the color of the grid (or not show it at all), and can use pinch-and-zoom finger maneuvers to change the size of the grid squares. The marked-up image can be saved to the camera roll—although be careful, once you save it to the camera roll you can’t open again to continue counting without a second grid appearing onto the image.
