I gave you 4 stars out of 5 stars because I noticed that the maximum size of the font is smaller than the size of font of the same app on iPhone. and some features on android are bit different than the features on the iPhone.

Thank you for your support! That's the use case that I did not anticipate to have. I've updated the app to support landscape mode. Please try again! Thank you for your feedback.

currently using this to communicate with a coworker, but I need the shake to erase and other functions to exist for android, not just iPhone 🙃
