The Bluetooth tracker market in numbers: shipments and growth
The Bluetooth tracker market is larger than most buyers assume and smaller than the marketing suggests, and the published forecasts are worth reading before you form a view on whether these things are a fad. The figures below come from the Bluetooth SIG's own market updates, which are built on datasets from ABI Research. They are forecasts rather than audited sales, and should be read as such — but they are the industry's own numbers, which makes them the most useful starting point available.
The headline forecasts
The Bluetooth SIG's 2024 Bluetooth Market Update, drawing on ABI Research data, set out the following.
| Measure | 2024 forecast | Later forecast |
|---|---|---|
| Total annual Bluetooth device shipments | About 6.9 billion | 7.5 billion by 2028 |
| Bluetooth Low Energy single-mode devices | 1.8 billion | More than double by 2028 |
| Share of Bluetooth devices including LE | — | 97% by 2028 |
| Personal item finding devices | 115 million | Roughly fourfold growth by 2028 |
| Commercial asset tracking devices | 107 million | 322 million by 2028 |
The compound annual growth rate the report attaches to total shipments over the five-year window is 8%.
Two things stand out. The first is the sheer ordinariness of the technology: at nearly seven billion devices a year, Bluetooth is not a niche radio but the default short-range link in consumer electronics. The second is that consumer item finding — tags for keys, bags and cases — was already a nine-figure annual category in 2024, and was forecast to grow faster than the market as a whole.
Consumer item finding and commercial asset tracking are not the same market
This distinction is routinely blurred in press coverage, and it matters when you read a figure.
Personal item finding means a coin-cell tag attached to a possession, located through a crowd-sourced network of consumer phones. There is no infrastructure, no installation and no recurring fee. The 115 million figure above refers to this.
Commercial asset tracking means tags read by fixed anchor points installed in a building or a yard — a hospital tracking infusion pumps, a warehouse tracking cages. It requires infrastructure, it is sold as a system, and its 107 million devices in 2024 sit inside contracts rather than on shop shelves.
The technologies overlap and the economics do not. A consumer buying a tag is buying into an existing network they do not own and cannot influence, which is why the question "whose network is it" matters more than any hardware specification.
What the growth is actually driven by
Three forces, none of them about the tags themselves.
The first is network coverage. A finding tag is worth exactly as much as the density of devices willing to listen for it, so the value of every tag sold rises as the installed base of listening phones grows. This is a classic network effect and it explains why the category consolidated around a small number of platforms rather than fragmenting across dozens of proprietary apps.
The second is component cost. Bluetooth Low Energy silicon has become cheap and extremely efficient, and the same trend that lets a tag run for years on one coin cell lets it sell for a few pounds. Our piece on what the Bluetooth specification says about broadcasting covers the mechanism behind that efficiency.
The third is the loss itself, which has not changed at all. People misplace keys and bags at the same rate they always did. What changed is that a solution became cheap enough to be an impulse purchase rather than a considered one.
What the numbers do not tell you
Shipment forecasts say nothing about whether a given tag will work for you, and it is worth being blunt about the limits of this kind of data.
They do not distinguish between platforms, so a figure of 115 million devices covers tags on several incompatible networks at once. They do not measure active use — a tag sold in a multipack and left in a drawer counts the same as one on a daily key ring. And they are forecasts, published in advance and revised annually, not a record of what happened.
The practical upshot for a buyer is narrow but real: a category at this scale is not going to disappear, replacement cells will stay available in supermarkets, and the network your tag depends on is not about to be switched off for lack of users.
How BlueTag fits the picture
BlueTag sits in the consumer item-finding column of that table and nowhere else. It is a coin-cell broadcast device that relies on the Apple Find My network — the largest of the consumer networks by device count — rather than on any infrastructure you have to buy, install or subscribe to.
That dependence is the trade, and it is worth naming. It means iPhone and iPad only, on iOS 14.5 or later, with no Android support at all. It means up to 60 m / 200 ft of direct Bluetooth link, an 80–100 dB buzzer for the last stretch, and passing Apple devices doing the work beyond that, each sighting encrypted so that only your Apple Account can read it. It also means no Ultra Wideband arrow, because that is a separate radio this tag does not carry.
What you own outright is the hardware: 36.3 × 36.3 × 9 mm, about 10 g, IP67 sealed, a user-replaceable CR2032 rated at up to two years. A box holds two tags, delivery is free within the UK, returns run to thirty days, under £15. The specification is here.
