Lost & Found Trackers (Keys, Luggage, Wallets)

The 2024-26 normalization: AirTag for keys + luggage + wallet is now the default for iPhone households. Tile is the second-tier cross-platform pick. For the broader family-location-of-people side see Family Location Sharing; for travel / luggage specifically see Travel Packing & Lost Luggage.

Apple ecosystem

• ★ ★ Apple AirTag — paid hardware ($29 each, 4-pack $99); the 2026 default for iPhone households. U1 ultra-wideband chip enables precise direction-finding ("Walk 3 feet to the right"). Crowdsourced via the Apple Find My network (every iPhone in the world, anonymously). Replaceable CR2032 battery, ~1 year life. Anti-stalking alerts built in.
• ★ Find My (Apple) — free; the umbrella app; pairs AirTags + Find My-network-compatible third-party tags.
• AirTag-compatible third parties (Find My network) — Chipolo Card / One Spot, Pebblebee Card, eufy SmartTrack — register with Apple Find My instead of (or alongside) their own networks. Useful if you want a wallet-card form factor.

Cross-platform

• ★ Tile (Pro / Mate / Slim / Sticker) — paid hardware ($25-35); the cross-platform default; works on iOS + Android via the Tile network. Acquired by Life360 2021. No UWB (less precise indoor finding). Battery-replaceable on Pro; non-replaceable on others.
• Chipolo One — paid hardware (~$25); cross-platform; loud alarm; Chipolo One Spot is the AirTag-compatible Find My version.
• Pebblebee Clip / Card / Tag — paid hardware; rechargeable (no battery to replace); cross-platform (own network) or Find My / Find My Device version.
• eufy SmartTrack Link / Card — paid; cross-platform via Find My (Apple) and own network.

Android / Samsung

• ★ Find My Device (Google) — free; the Android crowdsourced network (launched April 2024); finally a real AirTag analog. Compatible third-party tags: Chipolo Point, Pebblebee Tag, eufy SmartTrack.
• Samsung SmartTag 2 — paid hardware (~$30); Samsung-only for the Galaxy Find network; UWB on Galaxy phones for precise finding. The Samsung-house default.
• Galaxy SmartTag+ — earlier UWB version.

Specialty form factors

• Wallet-card trackers — Chipolo Card, Pebblebee Card, eufy SmartTrack Card, KeySmart SmartCard. Credit-card thin; ~2-year battery (not replaceable).
• Luggage — AirTag dropped into a checked bag has become standard advice in 2025-26; airlines (Delta, United, American, Lufthansa, KLM) now officially accept and use it for delay tracking. See Travel Packing & Lost Luggage.
• Pet-collar trackers (NOT pet care, but tags-as-collar) — out of scope per spec.
• Vehicle / motorcycle GPS — different category; Bouncie, Vyncs; cellular not Bluetooth.

What to actually buy

• iPhone household, single tag: AirTag.
• iPhone household, 4+ items: AirTag 4-pack.
• iPhone household, wallet card: Chipolo Card Spot.
• Android household: Chipolo Point or Pebblebee Tag (Find My Device-compatible) — newer than Tile, more precise.
• Mixed household: Tile or Chipolo (cross-platform native) — pick by who's most likely to lose things.

Privacy & anti-stalking

• AirTag, Tile, SmartTag all now have unwanted-tracker detection on both iOS and Android. Apple + Google released a joint spec in 2024.
• Don't put a tracker on a person without consent. Specifically illegal in many states; ethically clear-cut.
• Anti-stalking alerts can be noisy in valet / carshare / borrowed-car situations.

• Tile: $25-35 paid; battery varies by model.
