Why It’s Unique
Many maps rely on flat projections that distort scale, especially near the poles. The True Size app uses spherical geometry for consistent, realistic proportions — similar to modern GIS tools. Compare countries, continents, and even your own GeoJSON data on a dynamic globe.

From the creators of TrueSize.net, this official app brings the same interactive map tools to your device for easy, hands-on exploration. Rediscover the world as it truly appears — clearly, precisely, and interactively.

Ratings and reviews

really awful app, doesn't even upload, or doesn't even reload, doesn't even work at all, the whole app bugged or something. (Edited):- The bug is fixed under few days, love the moderation, everything is now accurate and no adds at all. awesome app if you're a geography(country) lover.

This app is great and all, but you and your team didn't add the mid ww1 years, Russian Revolution years and the actual borders of WW2. Thank you!

Fun app, real eye opener to the scale! I launched out of curiosity, to then find myself lost exploring for a while :) Coming to the realization how sizes of countries on the map projection hide their real size relationships, and how huge Africa is, was an eye opener. The app has lots of interesting features (including correct country sizes across the years). One idea: maybe a quick "quiz mode" would be fun? Player could choose larger from 2 random country pairs shown :)
