The optics on this seem to indicate that it is just a lateral flow test of some kind.

It's not even different. Instead of having to interpret a couple lines you have software interpret the strip and tell you over bt on your phone. So much tech for so little.

For an app that displays positive or negative, wouldn't it be cheaper/easier to use image processing to detect lines on the test?

Some tests do that but then you end up with a limited list of phones where the camera has been qualified. Better to go all the way to an eye-readable test.

In the Lucira test is a bit more justifiable it's a full molecular test, with built in controls, better accuracy than lateral flow. The optics is pretty neat too:
