Cartographer

Free, or $2.99 once

The map itself. Finds your PC on its own, shows where you are, remembers where you have been, and gives exact coordinates for any structure.

It will not show underground on someone else’s server, by design: seeing through stone is indistinguishable from cheating no matter what you meant by it, so below-surface mapping only answers for a world you host yourself. Ordinary surface mapping works anywhere, the same line JourneyMap and Xaero’s draw.

Free or paid

Same map. The paid one sees your real world.

Drag the handle. Left is Cartographer Free, drawn from your seed. Right is the paid app, drawing the blocks you actually placed.

What it does

The map that reads your actual game.

Most map apps redraw your world from the seed in their own code, so they drift from the real game. This one asks Minecraft’s own generator, inside your game, which is why its coordinates agree with /locate.

01

Your world at block level

The blocks you actually placed, drawn as themselves, with your live position and facing read from the game.

02

In 3D, sliced at your depth

Everything you explored as a model you can turn, textured with your resource pack. Underground, the map cuts through at your level, so you see the tunnel you are in.

03

Your builds, as built

Orbit it, fly through it, or cut it down to a height.

04

Structures with exact coordinates

Worked out with the same routine the game uses for /locate. Tap one for its position and distance.

05

Choose what it marks

Villages, trial chambers, monuments, strongholds and the rest: show only the kinds you want.

06

Past the edge of the loaded world

Zoom out and the terrain keeps going, computed from your seed by your own game.

07

While you play

Keep the screen on, or keep mapping in the background with a notification that stops it in one tap. Waypoints too, and other players if you turn them on.

08

Stream to your PC

Send the map to OBS for your stream, set up from the same screen.
