## Most critical reviews (4 lowest-rated)

### 1/5 — Funktioniert nicj

*2025-09-01, version 2.0*

Tolle Idee, wenn die App nur starten würde. Schade, das es nicht funktioniert.

### 3/5 — Schöne Idee

*2025-09-08, version 2.0*

Allerdings scheint mir die Datendichte zu ambitioniert. 
Selbst leichte Wellen im Papier führen schon zu Datenverlust - da muss das Papier sehr sorgsam gelagert werden

### 5/5 — Sehr gut

*2025-09-01, version 2.0*

Gute Verschlüsselung Alternative, was mir noch fehlt, wäre eine deutsche Übersetzung für Bildschirm Reader, denn ich nutze ein iPhone und VoiceOver Funktion hier wird mir allerdings nur englisch vorgelesen
Scream Reader auf Deutsch wäre klasse.

### 5/5 — Great idea well executed

*2025-08-30, version 2.0*

What a great idea and nicely implemented. The application password you set is stored on disk as a binary plist containing an encrypted keybag (derived key, salted, PBKDF2 with 10,000,000 rounds).

I wish it was open source. Or maybe a cross-platform CLI tool for decryption? It's difficult to rely on a tool for emergencies when it's only available on Apple's App Store and could be removed at any time. However, the author publishes the data format implementation.

I had trouble scanning high-density codes with lots of data using my webcams, but managed to do so using Continuity Camera and my iPhone. However, I'd personally suggest using low- density codes to have some margin of error and account for paper / ink degradation over time.

In my experience, the tool works best with smaller amounts of information because the generated QR codes use more redundancy and easier to scan.

One feature I’d like to see: Having an option to fill remaining space on a paper sheet with error correcting / redundant data in case one of the QR codes is degraded. A simple use case example: If the information to be encrypted only requires a single QR code, have an option to fill the remaining space on the paper with duplicates.
