When it comes to tracking a medical device like an insulin pen or EpiPen, choosing the right Bluetooth tracker matters. Apple AirTag and Chipolo are both excellent options — but they work differently, suit different phones, and have distinct strengths. Here's a straightforward comparison to help you decide.
The Short Answer
- iPhone user? Go with Apple AirTag.
- Android or Samsung user? Go with Chipolo.
Both trackers are supported by our PenGuard and EpiGuard adapter range, so whichever you choose, there's a compatible adapter for your pen or EpiPen case.
Apple AirTag
AirTag is Apple's own tracker, designed to work seamlessly within the Apple ecosystem. It uses Bluetooth and Ultra Wideband (UWB) technology and integrates directly with the Find My app on iPhone, iPad, and Mac.
Key strengths:
- Precision Finding — on supported iPhones, UWB guides you to the exact location of your tracker with on-screen arrows and distance readings, down to centimetre accuracy.
- Massive network — AirTag piggybacks on hundreds of millions of Apple devices worldwide to relay its location anonymously. Coverage in urban areas is exceptional.
- No app needed — it's built into iOS. No separate download or account required beyond your Apple ID.
- Replaceable battery — standard CR2032 coin cell, widely available, lasts around a year.
Limitation: AirTag only works with Apple devices. If you use Android, it's not an option.

Chipolo
Chipolo is an independent tracker brand with a strong Android and Samsung integration. Their trackers work with the Chipolo app (iOS and Android) and also integrate with Samsung SmartThings for Galaxy device users.
Key strengths:
- Android-first — deep integration with Samsung SmartThings makes it a natural choice for Galaxy phone users.
- Loud alert — Chipolo trackers are known for their loud ring, making them easy to locate by sound at home.
- Cross-platform — the Chipolo app works on both Android and iPhone, giving you flexibility.
- Community Find network — other Chipolo app users can help locate your tracker when it's out of Bluetooth range.
Limitation: Chipolo's community network is smaller than Apple's Find My network, so out-of-range location tracking may be less reliable in rural areas.

Which Matters Most for a Medical Device?
For tracking an insulin pen or EpiPen, the most important features are:
- Sound alert — both trackers ring loudly, so you can find your device at home quickly.
- Last known location — both show where the tracker was last detected on a map, useful if you've left it somewhere.
- Reliability — AirTag's larger network gives it an edge for out-of-range tracking in most locations.
For most people, the decision comes down to one thing: which phone do you use? Stick with the tracker that matches your ecosystem and you'll get the best experience.
