For some reason, this one keeps crashing I’m gonna try and fix it. It seems like a good one, but

### 1/5 — Crashing

*2026-08-06, version 2.4.1*

I have an iPhone 17, with lots of storage still, so it doesn't explain why the app crashes every single time I use it. I was able to scan one single card, and it just won't stop crashing.

### 1/5 — WAY too buggy

### 1/5 — Junk

*2026-06-18, version 2.4.1*

### 1/5 — Constant crashing

*2026-06-15, version 2.4.1*

This app would not let me scan more than one card without crashing.
