Do I need an AirTag if I use an iPhone, or will a cheaper Find My tag work?

For most iPhone users, a Find My–certified third-party tag like the UGREEN FineTrack or ATUVOS does the basic job of locating items on the Find My network for a fraction of the price. The trade-off, as multiple reviewers point out, is Precision Finding: only Apple's AirTag has the ultra-wideband (U1/U2) chip that gives you turn-by-turn directional finding when you're within a few feet of the item. If you mainly need to know which city or building your luggage is in, a budget Find My tag is fine. If you want pinpoint accuracy in your house, get an AirTag.
