Ratings and reviews

At the outset, app was great. But in the last few months, it's not usable. Can't get past "other lesion " page. This has been stated in multiple previous reviews and it still has not been fixed. And now the tables don't show up on app. UPDATE: August, 2025. Still no resolution and no updates since September, 2024.

hi, there is a problem with the app, orads section: nothing happens when i click on "other lesion", also when i click on resources and tables, the page appears black, there are no tables, and the link to orads full website is not functional. please fix this, because this app is awesome and i want to use it!

This app worked great until they did some update in the last 3 months or so. The O-RADS calculator doesn't work correctly with overlapping buttons, buttons that don't work, or text that isn't readable. The feedback button is non functional. On a samsung galaxy S24+.
