Promega Colony Counter

Is the tedium of squinting over agar plates counting bacterial colonies getting to you? Take the plates out of the lab! No, not literally. Snap a picture with your phone and you can make counting an out-of-lab experience. The Colony Counter app gives you a count estimate you can then manually refine. Save single plates or sets for later comparison. Happy Counting!
The fine print: Our app was tested with JM109 High Efficiency Competent Cells grown up in 50ml LB Medium; other plate and colony combos weren’t tested.

To enable the camera, go into the setting of your phone and turn on allow camera. After that, it works perfectly!

Incorrect counting. You should allow taken pictures for manually marking.

Camera used by another app. I rebooted n started . it just won't start.

Terrible app. Doesn't count very accurately, and worst of all has no ability for you to export the photos or data. iPhone version is much better. Do not rely on this app to handle your experiments

Camera issue can be solved by granting the app permission to use the camera.

Ale. M. Aug 2, 2016     

Is a good tool, is not possible to errase experiments.... is much better the Iphone version!!!
