Info about the app, screenshots, its features and an user guide is available here: https://github.com/anst270125/Binanz. You can download and run the release package(https://github.com/anst270125/Binanz), or clone the repo and build the app yourself. The app is already useful to me, maybe it could bring some use to you too. No user data (account or password) is needed, but the app obviously needs internet access in order to download price data.

I'm open to questions and suggestions
