Range is meaningless; the size of the finding network is not
A Bluetooth tracker has a range of a few tens of meters and that figure barely matters. What locates a lost bag is the finding network: every stranger's phone that quietly reports having seen your tag. The size of that network — and therefore which phone platform you and the people around you carry — is the specification that decides whether a tracker works in your town. Two practical details follow: whether the battery is replaceable or the tag is disposable after a year, and how loud the ringer is through a coat pocket. We compare network coverage, platform support, battery, ringer volume and unwanted-tracking alerts.
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.
Best for: A household on Samsung phones, in a country where Galaxy devices are common.
Apple Find My and Google Find My Device · ringer up to 120 dB · rings your phone back · colorful
Chipolo's dual-network tag: it works with both Apple's Find My and Google's network, rings loudly, and can ring your phone back from the tag itself.
Best for: Someone who loses their phone as often as their keys.
≈ $23
Apple Find My and Google Find Hub · USB-C rechargeable · 100 dB buzzer · four per pack
A dual-certified tracker that works on both Apple's Find My and Google's Find Hub, rechargeable by USB-C rather than running on a coin cell, with a stated 100 dB buzzer. Four in a pack.
Best for: A mixed household — some iPhones, some Android — that wants one kind of tag for everybody.
≈ $37
Apple MFi certified · Find My, iOS only · two per pack · protective cases included
An Apple MFi-certified tag for the Find My network, sold in pairs with protective cases. CYBERDOT states iOS only — it does not work with Android.
Best for: An iPhone household wanting several tags without paying Apple prices.
Apple Find My · double-tap to ring your phone · free left-behind alerts · four per pack
Four Apple Find My tags with a double-tap that rings your phone even on silent, and left-behind alerts through the eufy app at no extra cost.
Best for: Someone who leaves things behind rather than loses them — a bag in a café, a coat on a chair.
≈ $39
One tracker per object tracked is the principle of the device. A multipack covers keys, bag and luggage for a low unit cost.
A thirty-decibel tracker is not found under a cushion in a busy room. The stated sound level decides usefulness for the most frequent use, which is searching at home.
A tracker with a sealed cell is thrown away after a year; one with a coin cell opens by hand. The stated battery type decides the cost over five years, and the waste produced.
It depends on the compatible devices present around the object. In town it locates well, in a sparsely populated area it reports nothing.
Placing a tracker on a person or their vehicle without their knowledge is illegal. Manufacturers in fact build in alerts against that use.
It gives a position to pass to the police. Going to recover it yourself is inadvisable and sometimes dangerous.
About a year on a coin cell: that is what the Chipolo POP and the CYBERDOT state. Samsung states up to 500 days for the SmartTag2, and the UGREEN FineTrack Duo recharges over USB-C, up to 12 months per charge. A low-battery alert avoids discovering the problem at the wrong moment.
It sends a short signal at intervals. That is what allows a year of life on a coin cell.
Not always: each tag registers on one network. The CYBERDOT and the eufy work only with Apple Find My, the SmartTag2 with Samsung Find. The Chipolo POP and the UGREEN FineTrack Duo accept Apple or Google, chosen at setup, one network at a time.
Ratings vary: the SmartTag2 is rated IP67 (dust and brief immersion), the Chipolo POP IP55 (splashes only). On a keyring, it is a real criterion.
It relies on nearby devices passing by to report a position, which works in a city and not in a field. Network density matters more than the stated range.
Location depends on the density of surrounding devices: effective in town, silent in the countryside. Placing a tracker on a person without their knowledge is illegal, and a position found is passed to the police rather than acted on yourself.
There is no table here, and the reason is in the listings. The figure published most often across these 5 products is contents, given by 3 of them — short of the four in five a column needs to compare rather than to display gaps. Each product page says what its own maker published.
Specifications: manufacturer sheets for home security products and the matching Amazon product pages. Prices and availability: Keepa.
