How accurate is Find My for a tracker tag?
How accurate is Find My when the item on the map is a tag and not a phone? Two answers, and they are miles apart. Inside Bluetooth range of your own iPhone the tag can be made to ring, which is as accurate as you need. Outside it, the pin marks where some passing stranger's device last saw the tag, a street or a building, not a shelf. This explains the gap.
The short answer, in numbers
Four figures do most of the work here.
- 60 m is the Bluetooth reach at which a certified tag can be rung directly by your iPhone.
- 4.9 m is the accuracy GPS.gov, the United States government's public information service for the satellite system, gives for a smartphone under open sky, and that is the phone reporting itself, at its best.
- 80 to 100 dB is the alarm that closes the final few metres once the map has stopped being useful.
- Zero is the number of direction arrows a tag without an ultra-wideband radio will ever show you.
Read them together and the picture is clear. The map narrows the search to a place. Your ears finish it.
Where the pin on the map comes from
A tag has no satellite receiver and no mobile connection. It broadcasts a short, rotating, anonymous identifier over Bluetooth and nothing else.
When any passing Apple device hears that broadcast, it records its own location, encrypts the report against the tag's key and uploads it. You then download and decrypt the report. What you are looking at is therefore not the tag's position. It is the position of a stranger's phone at the moment it walked past, which, in a city, is close enough to be useful and in a field is not.
Three consequences follow, and they explain almost every complaint about accuracy.
| Where the tag is | What the map shows | How close it gets you |
|---|---|---|
| In range of your own iPhone | Live, with Play Sound available | Within earshot, so exact |
| Somewhere busy with people passing | A recent sighting from a nearby device | The right building or street |
| Somewhere quiet with nobody about | The last sighting, possibly hours old | The right area, at the time it was seen |
Why a pin drifts, and why a timestamp matters more than a radius
The single most misread element of the screen is not the pin. It is the line of text under it.
A location with a timestamp of two minutes ago in a busy street is worth acting on immediately. The same pin stamped nineteen hours ago tells you where the item was last seen by anybody, which may be the last place it was ever near another person, a parked car, a locked office, a hedge on a quiet lane. The tag has not moved on the map because nothing has come near enough to say otherwise, and that is a reporting gap rather than an error.
Density is therefore the real variable. A tag in a shopping centre updates constantly. The same tag in a rural lay-by might update when the post van goes past, and not again until tomorrow.
The realistic expectation to set
Treat the map as a postcode-level answer and the alarm as the street-level one. People who are disappointed by tag accuracy are almost always expecting a live dot they can follow like a taxi, and that is not what the technology is or claims to be.
How Orbit Tag helps
Orbit Tag reports through exactly the mechanism described above, because it is a certified accessory rather than a gadget with its own map. Its accuracy is therefore Apple's accuracy: the same relays, the same encryption, the same timestamp under the same pin.
Where the product does its own work is at close quarters, and that is deliberate. The alarm sits between 80 and 100 dB, loud enough to come through a coat, a cushion or a stuffed rucksack, and Play Sound reaches it anywhere inside the 60 m Bluetooth figure quoted at the top of this page. Noise is the part of a search a map cannot perform.
The remaining details exist to keep the tracker attached and alive long enough to matter: a 9 mm case, 36.3 mm across, IP67 sealing, a ring hole through the moulding with a pair of rings included, and a CR2032 good for roughly two years. It asks for iOS 14.5 upward, does nothing on Android, and carries no ultra-wideband radio, so the arrow row above stays blank for it.

Frequently asked
Why does my tag show a location from hours ago? Because nothing with an Apple device in its pocket has passed it since. The tag is not broken and its battery is probably fine; there is simply no one nearby to relay a fresh sighting. Somewhere with more footfall would update in seconds.
Can I follow a tag in real time like a phone? No. A phone reports its own position continuously over mobile data. A tag has neither a receiver nor a connection, so it updates only when a passing device chooses to report it. Anyone promising live tracking from a coin cell is describing a different product.
Would Precision Finding fix the accuracy? It would change the last ten to thirty metres, not the map. Ultra-wideband gives a bearing when you are already in the right room, so it helps most outdoors in large or noisy spaces where an alarm cannot be heard. We have compared the two properly.
