Ratings and Reviews
Was great when it was released but it does not work with recent Mac or Watch OS, has not been updated in 3 years so don’t expect it ever will.
Cool idea but doesn’t consistently work
Set it up. Worked fine at first. Was excited but didn’t have option to set it up as a glance on iWatch. Wrote developer about that but no response. Therefore, had to go thru a few extra steps to find it on iWatch. In that time could easily type in my password. Then it started only working 1/2 the time. I recommend waiting till it’s more perfected before buying. Great idea just needs to be easier to use and more reliable. To be fair, I have a 2012 computer. Maybe it’s more consistent with newer models.
not compatible with new devices
does not work with Mac OS High Sierra, which has been out for about 4 months.
