This app includes general maps of Finland (scales 1:4 500 000 and 1:1 000 000) and topographic maps at scale 1:250 000. Using the app doesn't require an internet connection. You can use pinch zoom or zoom in by double tap and zoom out by two finger tap.

Search list includes over 13 000 place names. Under the place name there is the name of the municipality where that place is and an optional place type (in Finnish). Heading button shows where the device is heading: 0° is grid north, 90° east etc.

With Location button you can load a map centered to your location. Your coordinates are shown in blue numbers and center of the screen is shown in black numbers. Gray grid has different size depending on zoom factor. You can see the grid size in the title bar. You can save the map to Photos app and for example email it from there.
