Here’s an app I made back in AppInventor for taking notes. You can set a PIN to hide notes you choose, you can attach an image to a note, you can chose from 5 different app themes, it has many more cool features. You can import the AIA to Thunkable and make your own, but it might need a few design tweaks to look good, because it was created in AppInventor without material design.
Where it’s avaliable
The AIA is here: SimpleNotes_OpenSource.aia (1MB)
It’s also on Google Play here: Simple Notes by SeableApps
I’m excited to see what people do with this! No credit is required for my code, feel free to do whatever you want with it. Redistribute it to any app store, make money off of it, I don’t care. It’s all yours.
If you see my apps on Google Play and want the source code for one, just ask me. (Don’t ask me for the Dice one though)
