OnePetri uses AI and computer vision to automatically detect and count plaques on petri dishes. It also performs common assay calculations based on these counts, primarily for bacteriophage plaque-based assays.
No, all image processing and detection are done locally on-device. Once installed, an internet connection is not needed for the app to function, though regular internet access is recommended for updates.
The app's models may occasionally miscount plaques. It is recommended that all counts be validated by manual counting or another established method, especially for critical experiments like phage titration.
Currently, OnePetri only works with circular petri dishes. Support for square and rectangular shapes may be added in the future if sufficient training data becomes available.
OnePetri is a paid application, available for $0.99. It does not have in-app purchases or advertisements.
OnePetri is available for iPhone, iPad, and iPod devices. It has an age rating of 4+.
Updates are likely to be released regularly. The latest version is 1.1.4, last updated on November 7, 2025.
Yes, OnePetri is completely open source. The initial training dataset and app source code are publicly available, and contributions can be made by visiting the OnePetri website.
