### 4/5 — Fantastic TOTP app

*2022-01-15*

This is probably the best freely available TOTP app I have seen on iOS. It’s ability to save your codes to iCloud is powerful. As my list of apps/websites that use TOTP has increased dramatically, there are two features I’d love to see added;
1) ability to search codes so I can quickly find the app/website I need a code for
2) ability to sort the codes alphabetically so that they are easier to scroll through

These two features would be great additions, but otherwise thanks for an awesome product!

### 5/5 — Works great but

*2022-01-06*

Works great but want an option to manually insert key instead of QR.
