Why didn’t I receive the PDF certificate via email?
Check your spam or junk folder. Ensure your email address is entered correctly in the app.
What if the test strip result doesn’t match the reference colours?
Use the app’s cropping and alignment tool to refine the photo, or select the closest matching value manually.
How is the pH Test performed?
