App lacks basic features, like, you cannot add a note after you scan device (such as “before meal”, “after meal” etc) or a custom note in text box, which, you cannot see what you’re typing because the text box is blocked by the keyboard and there’s no way around that. You can only enter note in “Manual“ mode, which defeats the purpose of scanning. App connects via NFC and gives a confirmation check mark but still says unable to connect and does not transfer results to app more than half of the time. Developers put in a bare minimum effort.
