I think it’s really cool and has good potential but...

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

Great concept but crashes

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.

Simply does not work.

The software is unable to identify tags under any conditions.
