Own an AltimeterThree?
FlightLab is free.
Every AltimeterThree includes a full FlightLab and Cloud Sync membership — no subscription, no expiration. If you don't own one and just want FlightLab on the web, it's a flat $2/month.
For AltimeterThree owners
Included with your altimeter
Free for as long as you own it
Activate from the AltimeterThree app for iOS or Android:
- Connect your AltimeterThree to the app over Bluetooth (you've probably already done this).
- Turn on Cloud Sync in the app's Settings and confirm your email.
- That's it — your membership activates automatically and your flights appear in FlightLab.
Already signed in? Just connect your altimeter once.

Common questions
- I already use the AltimeterThree app. Do I need to do anything?
- No. If Cloud Sync is already on, your membership converts automatically the next time the app syncs or you connect your altimeter. Nothing is interrupted.
- Our club or classroom shares one AltimeterThree. Does everyone get access?
- Yes. Every person who connects the altimeter in the app and signs in with their own email gets their own free membership. Shared units are a normal, supported use.
- What if I subscribe on the web and later buy an AltimeterThree?
- Connect it in the app and your membership becomes free going forward — you can then cancel the paid subscription in Settings and keep full access.
- Do both plans get the same features?
- Yes. There is exactly one FlightLab — same storage, analysis, comparison, and collaboration tools either way. The only difference is how you unlock it.
