I write code for a living, and a few years of that gave my neck an opinion about my career. The wearables felt like homework and the reminder apps just guessed on a timer, nagging me when I was sitting fine and staying silent when I wasn't.
So I built the thing I wanted: something that actually looks, actually knows my baseline, and otherwise leaves me alone. It runs on my machine all day. Now it can run on yours.
P.S. support@axlin.app goes straight to me, not a ticket queue.
