Currency adder (sumator walutowy)

Android project, generated using Android Starter.

Features

• manage your savings in multiple currencies
• see your total savings in any of the supported currency
• authenticate only via biometrics - your savings are safe from third party access
• by third party I mean everything - no analytics, tracking etc

If you don't believe my words, then just take a look at the codebase 😅 it is open-source after all.

Exchange rates are taken from National Polish Bank's API.
