I absolutely love the concept. The idea that it can actually see YOU make the sign and tell you if it's correct is absolutely revolutionary. However, the execution has a few crucial kinks that need to be worked out. For example the cameras says that I am to close for the sign to register. Which is imperative for the app to function. I feel like a simple zoom mechanism would fix this, and I really hope they do because the general idea really is amazing.

First off, I love the idea of this app, and the UI is really well built. I gave this a 3 / 5 stars because there is a flaw in the camera being slow to read the hands. I think with this, is because the camera lags a bit which causes it to read the hands as too far away or too close. A way to improve this would be to either change the speed of the software that reads through the lens, or maybe add something in to add weight to the balance of the lens. If the camera gets improved, It will be 5 star

Used on Samsung S6. Oct 13th 2020. Camera clearly sees my hands making the sign, however it doesn't respond! It's cool (and a bit creepy) how it can see my hands. I'd love to see this tech used as a free SLS (ghost hunting equipment) app. Overall the idea is brilliant. Using motion capture to teach and correct people's signage. However, I don't think the technology quite works as intended. Maybe push for better motion recognition software if possible.
