Hi! 

Not sure if you remember me but I kinda reviewed the prequel to this and I want to say that I love what your doing here! 

Just a quick suggestion though, not sure how many other people do this but I lot of times I'll watch a JOI video (usually from joidatabase) and they are almost always anime JOIs. I found that many times the AI model wasn't able to detect a lot of the body parts a lot of the time especially when they were first coming into frame. I'm not sure how this helps but I felt that it was important to give feedback..

Maybe you could use some of the frames from those videos which the AI struggles with to help train it?

Anyway I hope you are doing well and I wish to see more from you in the future!

P.S I also wanted to say that after a while of no detections, the app seems to stop working and not detect anything.. So if there is a way to fix that please let me know!
