WORKS ANYWHERE, NO CONNECTION NEEDED
The entire directory lives securely on your device. AviDecode never connects to the internet. You can access the directory on the ramp, in the cockpit, in a briefing room, at the construction site or factory, or anywhere else with absolutely no signal.

SEARCH YOUR WAY
Search by code or by term, and choose "starts with", "contains", or "ends with" matching to find what you need quickly, even with a partial or fuzzy memory of the term.

FILTER BY CATEGORY
Narrow results by country, location, entity, domain, and status in order to zero in on exactly the kind of code you are looking for.

TRANSLATIONS BUILT IN
Full translations in English, French, Italian, Portuguese, and Spanish, with an in-app language switch that changes both the interface and the data. No separate language packs to download!

BUILT FOR ACCESSIBILITY
Dedicated colorblind and low-sensitivity display modes adjust how translation states and category tags are shown, so the app stays easy to read regardless of color vision or light sensitivity.

PRIVATE BY DESIGN
No account, no sign-up, no ads, no analytics, no tracking. Your information is not collected. Your settings never leave your device. The dataset itself is stored in an encrypted local database.

A ONE-TIME PURCHASE
Pay once. Use offline forever. No subscription.

Whether you're studying for a rating, working the line, or just curious what a three-letter code means, AviDecode puts the answer in your pocket. Access over 90,000 codes with translations instantly, privately, and offline.
