User reviews

Doesn’t do anything

I am using FROG test strips- one of the most popular. The app doesn’t seem to recognize them and doesn’t appear to analyze or do anything

Response from developer

We're sorry to hear this wasn't working for you. FROG test strips have worked in our own testing, so we'd love to understand what happened on your end. Were you getting an error message, or did the scan complete but give unexpected results? A few things that can affect the scan are lighting, how the strip is held, and making sure the correct brand is selected before scanning. Please reach out at support@htremind.com with a screenshot or description of what you're seeing and we'll get it sorted out for you.
