Buying
A tracker has a range of a few tens of meters, and that figure is irrelevant. What locates a lost bag is the finding network: every stranger's phone that quietly reports having seen it. Which network, and how common those phones are where you live, is the entire specification.
Trackers are compared on range and decided by network.
The radio reaches a few tens of meters. What finds a bag left on a train is every passing phone that reports having seen the tag, and the density of those phones in your town is the entire capability.
A loud ringer, because a frequent use is finding keys under a cushion. Reverse finding — pressing the tag to ring your phone — because many people lose their phone as often as their keys. And a replaceable battery, unless you want a disposable object.
Left-behind alerts. Your phone notices it has walked away from the tag as you leave the café, which is the only feature in this category that prevents the loss rather than helping afterwards.
Lost, not stolen.
The best case. A tag on keys or a wallet with a local chime solves the everyday problem completely.
Where knowing a bag is at another airport is genuinely useful, if not immediately actionable.
Where a tracker may show a location, and where what you do with that is the important part.
Where dedicated trackers with their own connectivity work far better than consumer tags.
| Your use | The device | The limit |
|---|---|---|
| Keys at home | A consumer tag | Works perfectly |
| Luggage | A consumer tag | Location, not retrieval |
| A bike | A dedicated tracker | Battery and subscription |
| Stolen goods | Either | Never retrieve it yourself |
Trackers are forgotten until needed, and by then the battery is often flat. A tag that has been silently dead for months gives exactly the same result as no tracker at all, which is the whole failure mode of the category.
Location data cuts both ways.

Up to 500 days · IP67 · compass view · NFC lost mode · Samsung Find network
Samsung's tracker for the Galaxy Find network: up to 500 days of battery, IP67 dust and water protection, a compass view for the last few meters, and an NFC lost mode a finder can tap.

No, and no page here will suggest trying. Anti-stalking rules mean an unknown tag alerts the phone it is traveling with, so whoever has it is told — and following a tag to an address is dangerous. Trackers find things you mislaid.
The one most common around you and among the people you live with. Apple's is very widespread in the United States; Samsung's is strong where Galaxy phones are common. Dual-network tags remove the question in a mixed household.
Finding things you have mislaid, particularly at home. That is the everyday problem they solve best.
Consumer tags depend on other people's phones passing nearby, so they work well in cities and poorly in empty areas.
Often a long time on a coin cell, but a flat tracker is no tracker. Replacing at the first warning is the whole maintenance.
Modern tags warn people who appear to be followed by an unknown tag. Take such an alert seriously if you receive one.
Tags suit keys and bags. Bikes and vehicles are better served by dedicated trackers with their own connectivity and power.

Prices quoted in these summaries are dated readings. The live price is shown next to each product.
Cameras, alarm kits and safes swing by thirty dollars or more across the year, and the biggest "discounts" often land at prices the same model sold for six weeks earlier. UniverTrack tracks the real price history across retailers, spots fake reductions, and alerts you when it is genuinely the moment to buy.
