This feedback is to the developer.

This app is really helpful for students and competitive exam aspirants but I don’t know if it’s only with me but for some I’m unable to watch the solution videos on landscape mode. The app just doesn’t support landscape mode and therefore I have to watch the video in portrait mode. It’s really difficult as the video is shown in tiny window. I’m using IPhone XR with the latest IOS and updated DOUBTNUT app. Hoping for a fix for this issue from the technical team. Thank you

Excellent app for Q&A

I’ve been using Doubtnut on the web browser for a couple of years now and was so happy when I saw that they have launched an app for iOS . That just makes the process of asking questions so much easier using the phone camera.

There are some bugs, but I assume that they’ll fix it soon.

All the best Doubtnut.
