The website doesn't describe what specifically the glasses do to improve focus. It doesn't state there is a camera so if I have to tap something in an app that says I started task X, and veer off track and start browsing HN, how do the glasses help? I'll guess that everything happens in the companion app and the glasses are just a couple sensors/mic/speakers. Isn't forcing the user to check their phone to check their "productivity" counterproductive? Phones are the biggest distraction people have. What happens when the frame design you chose falls out of fashion like when people like "frameless" glasses or something else?
