A wearable smart posture trainer that helps users to stop slouching.
It works decently well for what it's supposed to be - it buzzes anytime you slouch over a little bit, which serves as a good reminder to sit up straight. Ultimately I wasn't able to stick with it long enough to see results, and it was pretty expensive for what it was, leaving me a little disappointed. However, I think the blame for that goes mostly on me.
Any time I bent over to pick anything up it would vibrate, which was pretty annoying. I wish there was a better way to separate normal bending over movements from actual slouching
