Chipolo are very specific in their online FAQs that the One Spot will only work with Apple's Find My app, and not their own Chipolo app [1]. Unfortunately that means all the niceties of their current app (range alerts, etc) won't be supported.You get free "out of range" alerts with Chipolo's other trackers. I hope this new ONE Spot comes with that feature.
As for not having UWB, that isn't a deal breaker for me, as I'd just get it to play a sound if lost in close proximity.
I was looking at picking up a few of these, but don't think I will now given that 1/ there are no reviews out for the One Spot, and 2/ they are only shipping in August. Not sure why they'd whip up a big marketing campaign and then not be able to deliver the goods.
