Unbelievably wasteful and overly complicated. If you have these tests, return them. The testers they use are the same as other easier to use lateral flow tests. The app requires personal information (name, email, home address etc.) before it will even give you the instructions. The tester itself uses the same type of test strip that other tests use but uses an internal LED to "read" the result. Absolutely pointless when other tests do the same thing without the extra bells and whistles.
