Somatic coliphages are viral indicators of the water quality which monitoring is requested in some water quality regulations worldwide. This app is designed to be used with the BPF-SE kit (Bluephage S.L) to provide the result of the somatic coliphages concentration of 100 ml water sample. The kit is based on a patented technology that allows to obtain the results after 6.5h of incubation. The user must register the sample and take a first photograph of the Enumera try following the instructions provided. After the incubation time, it is notified to take a second photograph. The app detects the number of wells that have changed from yellow to blue-green and return a diagram of the Enumera try that the user must validate. When this is validated, the Bluephage app provide the result of the concentration of somatic coliphages of the sample and a report of the analysis.
