I've got a FR945 that I've been using as my daily activity tracker. I haven't had to deal with it lately, but historically at work I've had to spend weeks at a time outside of cell range and without wifi, with the only internet being a work computer that I can't install anything on (i.e. express). Does anyone know how many days worth of basic activity tracking (steps, HR, body battery etc) the watch can store before syncing?
