Using the U1 chip for precise location finding in the local area doesn't appear to require using the Find My network for items. That API has been opened up to all 3rd party developers - probably not initially (the "we can't get access to the U1 chip" was from May 4th, 2019. It was opened up to 3rd party developers with iOS 16 ( https://www.macrumors.com/2022/07/20/ios-16-expands-u1-enabl... ).

For "find my" integration this would suggest two things.

First, that Find My should also query some 3rd party services for location of items - that I should be able to register a 3rd party with a standard API (akin to IMAP for email) that has location tracking info. That's reasonable - I look forward to a standard (and secure) API that doesn't leak my own location data when querying it.

Secondly, if it was "I want tiles to seamlessly be found by Apple devices just like AirTags are - the entire Apple network can find them" this gets into a question of how much cryptography and security would Apple need to open up to have 3rd party BLE devices ping to other services outside of their control that may leak the location information of people walking past them. Why should {arbitrary phone creator} need to ping a 3rd party whenever someone comes within range of the BLE device? That is, if Android devices aren't required to ping Apple's Find My network when in range of an AirTag, why should Apple be required to ping Tile's servers when in range of a Tile?

> how much cryptography and security would Apple need to open up to have 3rd party BLE devices ping to other services outside of their control that may leak the location information of people walking past them.

None, simply proxy it through Apple's existing servers and do not include any information about the device that found the tracker. If you are worried about rogue devices telling iPhone to ping rogue services, then just add a service whitelist to the scheme: Apple trusts Google's service and Tile's service, Google trusts Apple's service and Tile's service, but <random URL> isn't going to get pinged.

Now just make a process by which you prove legitimacy in order to get added to the list and require platform approval.

> Why should {arbitrary phone creator} need to ping a 3rd party whenever someone comes within range of the BLE device?

Because if every phone could ping the network associated with every tracker, then the strength of the network is all participating devices, not just OEM's brand. Apple gets the benefit of having a better Find My network outside the US where Android dominates, and Android gets the benefit of a better Find My network inside the US where iPhone dominates.

> That is, if Android devices aren't required to ping Apple's Find My network when in range of an AirTag, why should Apple be required to ping Tile's servers when in range of a Tile?

Required is a strong word, but Android should ping Apple's network when it sees an airtag, and I bet Google would take that deal if it were available.

All this is sidelong to the point though, that Tile cannot build an app that iPhone users can use that can tie into the beacon functionality the iPhone is already doing in order to enable Tile users with iPhones (that is, those iPhone users with the Tile app installed) have as reliable and friction-free an experience as iPhone users have with airtags.

Doing a "ping this other service" leaks information about the device that has been found. It also opens up Apple to knowing about who found the device or where it was found from information sent across the network. This is an important thing in security of the AirTag (and the rest of the Find My network) - the person detecting the BLE message has zero knowledge about it (other than its existence), Apple has zero knowledge about the person finding it or the device - only the Apple account that is associated with, and the person who owns the Apple account only has knowledge about where and what device - not who found it.

To not compromise the security of the Find My network, other vendors

> In addition to making sure that location information and other data are fully encrypted, participants’ identities remain private from each other and from Apple. The traffic sent to Apple by finder devices contains no authentication information in the contents or headers. As a result, Apple doesn’t know who the finder is or whose device has been found. Furthermore, Apple doesn’t log information that would reveal the identity of the finder and retains no information that would allow anyone to correlate the finder and owner. The device owner receives only the encrypted location information that’s decrypted and displayed in the Find My app with no indication as to who found the device.

This would be an opportunity for Tile to work at trying to establish a standard like was done with UWB ( https://www.nxp.com/applications/enabling-technologies/conne... ) so that multiple vendors could use the technology and chips for interoperability.

Apple giving their tracking product a 3 or 4 year head start over it's competitors.

If you're going to compete against other products on your platform, give it a level playing field.

From 3 years ago https://techcrunch.com/2021/01/05/tile-to-launch-to-launch-a...

> Tile is preparing to introduce a new product this year that will serve as a rival to Apple’s long-awaited AirTags and other lost-item trackers coming to the market, including those from Samsung, TechCrunch has learned. While previous Tile trackers have leveraged Bluetooth to help users locate lost items — like a misplaced set of keys, for example — Tile’s new product will take advantage of UWB (ultra-wideband) technology to find the missing items. It will also use augmented reality to help guide users to the lost item’s location via the Tile mobile app.

> ...

> Apple last year began to give third-party developers access to its U1 chip, which uses UWB technology to make the iPhone spatially aware, via its “NearbyInteraction” framework. Some Android devices also ship with the technology. It’s unclear to what extent Tile is using the new frameworks with its forthcoming product, and the company is likely under NDA with regard to its work with Apple specifically, per earlier reports.

> ...

> Meanwhile, according to a new research note from analyst Ming-Chi Kuo, Apple will reveal its own Tile competitor, AirTags this year. Apple has already all but confirmed AirTag’s existence, as it even accidentally published references to its lost-item tracker in an official support video at one point. Leaked images of the AirTags also began to circulate this week, adding fuel to these reports of a “soon-ish” AirTags launch.

> A UWB-powered tracker could help allow Tile to maintain its position in the market. Tile, as of last year, had sold 26 million Tile devices, and was locating around six million items per day across 195 countries. Tile’s website now says its devices reach over 230 countries and territories. With this scale, Tile today leads the market. But Apple’s AirTags could have a first-party advantage with deep integrations into its “Find My” app — a concern that was brought up by Tile in last year’s antitrust hearings in reference to how Apple wields its platform and market power to overrun competitive businesses.

I would like to see an integration similar to how mail and homekit work for the Find My : Devices. Enter in the server and account info and be able to get the location of a device registered to that service. Note that that has all sorts of privacy issues if not properly designed.

However, such integration would also eliminate the moat that tile perceives that it has for its product and the differentiation for it.
