Official signs, made easy to learn
An app to learn to read the signs around us: on the road, at sea, at the airport, on weather maps and on chemical labels.
Official signs, written for engineers.
Sign standards are written for engineers and authorities: long manuals full of codes and technical drawings. Drivers, sailors, students and travelers need the opposite: what each sign means and what to do, in their own language. Signopedia turns those manuals into cards anyone can learn on a phone, offline and without losing what the official source says.
Two apps, and everything behind them.
iPhone app
Cards, search, favorites and a learning game, in six languages.
Android app
The same product, with the same packages and the same game.
Content pipeline
Tools that turn official documents into packages of cards: drawings, texts and translations, checked before every release.
Product site
Home, privacy, support and terms, in English and Spanish.



From the official manual to your phone.
Decisions that respect the source and the reader.
- 01
Faithful drawings
Every sign is redrawn as clean vector art from its official source, keeping the exact colors and shapes, and checked by laying it over the original.
- 02
Offline and private
Packages live inside the app. No accounts, no ads and no tracking: everything stays on the phone and works without a connection.
- 03
A game that tracks what you know
Each right answer adds a point to a sign and each mistake takes one away; at three points it is learned. At 80% of a package, its challenge unlocks.
- 04
Sources on every package
Each package cites the standard it comes from, the body that issues it and the permission under which it is used.
The signs, by the numbers.
