    21 - Earn Bitcoin beta Report

    Google Pixel XL 2, Android 8.1.0; Samsung Galaxy Note 4, Android 6.0.1

    Do you like Bitcoins?

    21 is a very interesting app which allows you to complete simple tasks in order to earn some bitcoins. It requires your account to be verified and you will also need a Coinbase account in order to be able to collect your rewards. I like the concept in general but I was not able to test it fully because I am still waiting for the account verification.

    The app has a good and quite unique design. I found a couple of issues there:

    Device: Samsung Galaxy Note 4, Android 6.0.1 App version: 1.3.0:2

    Icons on the profile page are trimmed. See the screenshot.

    The user can switch "Link email" checkbox to the ON state without choosing a google account.

    • Steps - open app - tap on the profile icon - select Gmail integration - tap on the Account check box - see an account selection at the google account chooser intent - tap outside of the selector in order to close it
    • Expected - check box is in the OFF state b/c no account was chosen
    • Actual - check box is in the ON state

    App crashes if the user taps on the Whitelisted emails menu option

    • Steps - open app - tap on the profile icon - select Gmail integration - tap on the Whitelist menu option
    • Expected - the user can see a new view
    • Actual - app crashes

    How many bitcoins do you have?
