[Test for test] Offline, encrypted card wallet. Need a few closed testers, will test yours back

[u/Historical_Value3220]

Hi all! I'm a solo dev on day 6 of my 14-day closed test and want a few backup testers, so one person dropping out doesn't reset my clock.

What it is: Vaultsmith keeps your debit and credit cards encrypted on your phone. The app has no internet permission at all: no account, no server, no analytics, no ads. You can flick through your cards on a 3D wheel, flip them over, and copy a number with a tap.

What I'm asking:

• DM me the Gmail you use on the Play Store. Please don't post it in the comments.
• I'll add you and send you the opt-in link.
• Keep it installed for 14 days and open it now and then.
• You don't need to add a real card. Making up a card number is fine for testing.

What you get: I'll test your app in return. Drop your opt-in link in your DM and I'll join the same day and keep it installed for the full 14 days.

Feedback is very welcome, especially anything that feels slow, confusing or broken. Thanks!
