Colony Counter: CFU Calculator

Colony Counter counts colonies on lab plates from a photo. Take a picture or pick one from your library and the count appears in seconds, with every counted colony painted on the photo so you can check it at a glance. What it counts • LB plate colonies: bacterial colonies such as E. coli, with CFU/mL and transformation efficiency • Crystal violet colonies: stained cell colonies in dishes, 6/12/24-well plates and flasks, with plating efficiency and surviving fraction • Zebrafish embryo survival: live and dead embryos counted separately, with the survival rate Features • Automatic plate and well detection, adjustable with a finger • Touching colonies are split; dense clusters are estimated from their area • Tap to add or remove a colony, with undo • Count many photos at once and see a per-photo table • Enter the dilution and plated volume to get CFU/mL • Keep a log, copy or save it as…
