CAMOUFLAGE: Change the app icon and name to a seemingly harmless one, such as a calculator or a camera.

Thank you for your nice words! <3 - we are working on an update for the f-droid store, it will be ready by February :) - bulk imports are harder to implement, so we are currently fundraising for it. If you have any other feedback, please write to us: contact@tella-app.org

Oh, thank you for the review and for reporting this! We believe is related to a bug that the new release (2.18.0) should fix. After we publish 2.18.0 (next week) if the problem persist in your phone, could you please let us know? https://tella-app.org/contact-us. Thank you!

Editing as requested. Overall, this is a great app; my confusion stemmed from my misunderstanding that the app installed its own calculator for camouflage. As a recording tool, it is great, and I highly recommend it. I set up a numeric pin for the app - then I camouflaged it behind the calculator. The trouble is, my pin begins with a zero, and the calculator blanks out an initial zero! So I'm unable to get to my Tella app now. 🙄 HELP!

Hello! After the email exchange we had, it would be nice if you could change your rating, because this was not a bug on Tella but a confusion about which app was the Calculator. Low ratings affect our discoverability. Thanks!
