SKYTAG I vs SKYTAG II vs SKYTAG Button: Honest 2026 Comparison

TL;DR: If you just want a tracker that works, get the SKYTAG Button ($29). If you have a big house and lose things in the couch cushions, get the SKYTAG II ($45) for UWB precision. Skip everything else unless you have a specific use case.

I designed all six SKYTAG trackers. I'm going to give you the honest comparison — including which ones I'd actually buy and which ones I wouldn't.

Quick comparison table

Which one should you actually buy?

Best for keys: SKYTAG Button ($29)

The Button is what I'd actually buy for my own keys. It's a single button with a 100dB buzzer, IP65 water resistance, and a replaceable CR2032 battery. The shape is intentional — it doesn't catch on stuff in your pocket, and the button doubles as a test trigger for the buzzer.

Best for big houses: SKYTAG II ($45)

The II adds UWB (ultra-wideband) precision finding. Instead of "your item is somewhere in this room," you get an arrow on your iPhone that points exactly to the item within 10cm accuracy. It's the same technology AirTag uses.

But — and this is important — most people don't need UWB. If you live in a 600 sq ft apartment, the precision finding rarely triggers. If you live in a 2,500 sq ft house with a basement and an attic, the UWB matters.

Best original: SKYTAG I ($25)

The I is the original 2018 design. I still have one on my keyring from 2019, and it still works. The 1-year CR2032 battery is easy to replace, the IP67 rating is overkill for keys, and the 200m Bluetooth range is fine for any normal home.

It's not the most exciting tracker, but it's the one I trust. When my team builds a "new and improved" version, my keyring still has the I on it.

Specialty trackers (skip if you don't have a specific need)

SKYTAG Coin ($35) — 2mm thin, magnetic mount. Cool for mounting on metal surfaces (laptop, bike frame, fridge) but the CR1220 battery only lasts 6 months. Full review →

SKYTAG Card ($35) — 1.5mm credit card form factor. Slides in your wallet. Qi wireless charging is the only SKYTAG that does this. Full review →

SKYTAG Bike ($79) — GPS + Bluetooth dual-mode with tamper alerts. Built for cyclists who actually lock their bike outside, not for the $200 commuter bike. Full review →

What about AirTag?

I get asked this a lot. Here's my honest take as the engineer who designed the SKYTAG line:

• AirTag wins on network: More Apple devices in the wild = better crowd-located finding. SKYTAG uses the same Apple Find My network, so it's similar — but AirTag has a 3-year head start and Apple has a marketing budget.
• SKYTAG wins on hardware: Replaceable batteries, louder buzzers (100dB vs 88dB), IP65 vs IP67 (similar), lower price for the same core function.
• AirTag is fine if you trust Apple with your location data more than a small Hong Kong OEM. That's a legitimate choice — Apple's privacy policy is published, mine isn't, and the SKYTAG firmware is closed-source.

Who should NOT buy a SKYTAG

• You have a lot of Apple devices around you but no other people nearby (SKYTAG and AirTag both depend on the Find My network of nearby Apple devices)
• You want a fully open-source tracker (SKYTAG firmware is closed — try the OpenDuck project if you want open hardware)
• You're in a country where Apple Find My doesn't work (Mainland China, parts of Africa, etc.)

The bottom line

Six trackers, three that matter for most people (Button, I, II), three specialty (Coin, Card, Bike). If you want one, get the SKYTAG Button for $29 and stop thinking about it.

I'm the engineer who designed these. I'm not going to tell you to spend more than you need to.
