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. In other words, white on yellow; that’s it. ## Key features - Photograph agar plates - Estimate colony counts - Manually refine counts - Save plates for comparison - Out-of-lab counting ## Recent user reviews (10 of 15) All indexed reviews: https://appshunter.io/ios/app/promega-colony-counter/id620431249/reviews.md ### 3/5 — Doesn’t work on modern phones with macro photo capabilities *2025-02-27, version 1.5* This worked on my 7 year old super old iPhoneX but doesn’t work on my new one because the only camera this app can control has a minimum focus distance that is too far away to capture a 10cm dish, and the app is not able to use the macro photo lens for whatever reason. ### 1/5 — Doesn’t really work *2025-01-06, version 1.5* Will add random colonies and ignore very obvious colonies ### 3/5 — Great app buuut. *2021-12-10* Great app but it keeps crashing and now has my plates hostage :( ### 2/5 — Eh, not the best *2021-05-31, version 1.5* I liked the ability to manually add missed colonies, but it can’t handle writing on the plates and the counts seemed to be off much more than CFU.Ai. ### 1/5 — bad *2020-03-16* very innacurate ### 5/5 — Really good for 40-400 colonies *2018-01-10, version 1.5* With +/- 2-3% after zooming in to edit, using S. cerevisiae 40-400 colonies,per microbiology 101, on 10 cm Petri dish. ### 5/5 — Very Good *2016-06-25, version 1.3.1* Create app but don't think the results are very accurate 😊 ### 5/5 — VERY GOOD *2016-03-11, version 1.2* help me a lot...^^ ### 3/5 — Helpful, but frequently misses colonies *2016-03-09, version 1.2* 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. ### 1/5 — Does not even work *2015-09-15, version 1.2* It literally did not select a single colony ## Frequently asked questions about Promega Colony Counter ### What is Promega Colony Counter used for?
