📝 About this app
Customisable offline map from Openstreetmap with contour lines in which even the smallest paths and trails are shown.
POIs are grouped into categories and can be displayed as layers. For example, you can display all restaurants, public transport lines, banks, hiking trails, charging stations and doctors on the map. The size and overlap of the icons can be adjusted to improve clarity.
An integrated database allows you to search for POIs as well as a large number of streets, towns, villages, districts, etc. The search can be filtered by category and/or distance.… View full description on the official store →

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
