## QuantOn Cal Description
*** This App requires devices with built in camera and camera light. ***

***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 

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

## QuantOn Cal Reviews in Canada

### ****- "Works fine"
There’s a high potential for user error here, but if you carefully follow all the steps, it works.
-- Liza8375726, 2025-10-16

### *---- "L’app n’ouvre plus"
Depuis que j’ai mon i-phone 16 et que la dernière mise à jour d’Apple a été fait, l’application n’ouvre plus… ça me dit que l’application n’est malheureusement plus supporté par mon appareil ou mon système d’exploitation. J’ai téléphoné chez Dynacare et ils sont incapables de m’aider !!!!
-- Freddichou, 2025-10-11

### *---- "Seriously"
The app sets a timer but it’s completely silent when it goes off so of course you miss it unless you are hovering over it for 15 minutes or set a separate timer.
-- Appleuser1182, 2025-08-22

### *---- "Waste time"
This is not related to phone or iOS version, just can't pass the camera test no matter how you scan it. Had to switch to manual test process.
-- HanakoMW, 2025-07-10

### *---- "Useless"
Won’t work on iOS 18.
-- Chris83383, 2025-05-08

### *---- "Waste of my time"
Absolute waste of my time several times now. Does not support iPhone 16.
-- JocB80, 2025-02-11

### *---- "Absolutely useless. 100% buggy code."
I’ve used this for multiple tests and it never works. There is always an error when I go to scan the final test - the lighting is off, the control line can’t be seen, etc. By the time you get the test scanned, the 2 minutes is up and your results are deemed invalid.
This is especially stupid because you can restart the 15 minute timer in the previous step as many times as you want - so you could hypothetically wait hours to scan your results, rather than the required 15 minutes, but as long as you scan the test within the required 2 minutes on the last step, it will be deemed valid. So incredibly frustrating.
-- _ashley12345, 2024-12-06

### *---- "App won’t scan"
App will scan the two camera tests, then it will scan the patient code but then during the test it asks you to scan the patient code again and the app freezes.
-- XxSoniqxX, 2024-11-02

### *---- "App doesn’t work"
Can’t even get passed the scan test part of the app, it won’t focus when it is in scan mode. Faulty app. Embarrassing.
-- Some trying to use app, 2024-03-09

### *---- "Not working on my new iPhone 15 Pro"
I changed from iPhone 11 Pro to 15 pro and the app is not working anymore. 
I have a message saying the iPhone or IOS version is not supported.  I am on IOS 17.2.1

Please update your app to support newest cellphone and IOS.
