Comments on QuantOn Cal for Android

★★★★★ Tal Risin · Jun 27, 2022
App works well, had no problems with any of the steps and the test result came in a few moments. On Galaxy S21 with android 12
★★☆☆☆ Heather Murray · Apr 28, 2026
A clunky, frustrating experience. The tape isn't strong enough for the paper to stick to the toilet bowl, so I used a lot of masking tape to help. When I photographed the test results (on time) it took so many tries for the system to read it that it was past the 2-min mark and may not be accurate? But, I took the photo in the same place and lighting as the successful test photo (which took a lot of tries too!) They say you only need 18 minutes, but it took me about twice that. I hope it works.

Trash. Changes what devices are compatible within weeks. Bought a new phone that was compatible. When it arrived they removed it from the list.
★☆☆☆☆ DJ David · Aug 13, 2022
I downloaded the app, and it said that my phone is not supported, although I have a new phone (Poco x4 gt) Android 12. I tried it with my 2 old phones (Redmi Note 8 pro) (Samsung s8) and it worked, but I couldn't even do the camera test, the first scan worked but the second always telling-problem with lightning 0x10... Repair it please and do something that your app will support my phone...

***Please see www.quantoncal.com for a full list of supported devices and operating systems.***

This application is a monitoring tool for your IBD inflammatory status.

When you are suffering from IBD (inflammatory bowel disease), you need a reliable and convenient therapy monitoring to avoid severe inflammatory phases, which cause uneasiness and pain.

The QuantOnCal® test system consists of the QuantOnCal® app and the rapid test for human calprotectin – both easy to use everywhere. Monitoring IBD with the biomarker calprotectin means early indication of an inflammation before clinical symptoms arise.

The QuantOnCal® app calculates the results of the rapid test for calprotectin in stool. High calprotectin levels correspond to high inflammatory activity. The test result is indicated on your smartphone screen and immediately sent to your doctor. The doctor evaluates each result and decides whether you need further assessment of your therapy.

In order to use QuantOnCal® just contact a medical practitioner who participates in this program. Please find further information here http://www.quantoncal.com

Please notice that the app will not run on an iPad as it requires an camera light.
