## Most critical reviews (4 lowest-rated)

### 1/5 — Simply does not work.

*2022-11-06*

The software is unable to identify tags under any conditions.

### 2/5 — Great concept but crashes

*2019-02-21*

When I open the app on my iPhone X I just see a black screen. No camera input. Always crashes. Would love to see this working.

### 3/5 — I think it’s really cool and has good potential but...

*2020-01-19*

How do we use udp, also how do we make it do autofocus?

### 4/5 — Camera intrinsics?

*2025-05-25*

This is a very useful app, and I am able to capture the packets that it produces on UDP, however, it is not clear what to do with that data?  The author doesn’t specify which resolution he uses, so calculating camera intrinsics becomes a guess work.  Camera data for iPhone is well known, so it would be good to provide camera intrinsics inside the app.
