App Profile: Promega Colony Counter

This is a very helpful app but unfortunately it frequently miscounts colonies or counts colonies where there are none. The app is makes it easy to go in by hand and edit the count however if you are working with a plate that has tons and tons of colonies there's no way you could manually find all the colonies that were miscounted by hand. And this app is only good for 10 cm dishes. So helpful for very basic tasks, but not quite all the way there yet.

The cfu counter is way off. It was not even close to what my estimate was. Don't waste your money for now. Maybe wait until they come out with a new update

I bought this because I read online how good it is. I need to count lots of E. Coli and so I don't have white colonies on yellow agar (nothing in the literature I read mentioned this limitation). This means the automatic count doesn't work. It counts more glare or reflections than true colonies. On top of this major limitation, the program is very clunky. There is no way to import pictures. So I have to take the picture on my iPhone, my colleagues can't help me. There is no way to save the picture to my photos and then export it. The zoom feature is far from ideal. As my colleague said today, it just easier to use the old fashion method of counting colonies. I regret the purchase.
