StreetComplete
An easy-to-use Android app that lets anyone contribute to OpenStreetMap by answering simple questions on location.
What is StreetComplete?
StreetComplete is an Android application that simplifies contributing to OpenStreetMap by turning map editing into a series of simple, location-based questions. It automatically identifies missing map data nearby and allows users to fill in details—like road names or business hours—through an intuitive Q&A interface, with edits uploaded directly to OSM. The app is designed for offline use, making it ideal for on-site surveys.
Android users interested in improving OpenStreetMap data without technical expertise, including casual mappers, local community volunteers, and field surveyors.
It uniquely lowers the barrier to OpenStreetMap contribution by eliminating the need to learn OSM's complex tagging system, offering a gamified, question-driven workflow that works offline and is accessible to complete beginners.

Easy to use OpenStreetMap editor for Android and iOS
Use Cases
Best For
- Casual users who want to contribute to OpenStreetMap without learning tagging schemes
- Local community groups organizing map-a-thons or neighborhood mapping events
- Field surveyors collecting point-of-interest data offline
- Educators introducing students to collaborative mapping projects
- Improving map details like road names, surface types, and opening hours in your area
- Gamified mapping experiences that encourage exploration and discovery
Not Ideal For
- Advanced OpenStreetMap editors needing to apply complex tags or perform bulk data imports
- iOS users or projects requiring cross-platform mapping tools, as the app is currently Android-only
- Teams looking for real-time collaborative editing features, since StreetComplete focuses on individual, offline surveys
Pros & Cons
Pros
Explicitly designed for users with no OpenStreetMap expertise, as the README states it 'can be used without any OpenStreetMap-specific knowledge.'
Built for field surveys with economic data usage, allowing contributions without an internet connection, as highlighted in the description.
Automatically generates nearby quests for missing map data, transforming editing into an engaging, location-based activity with interactive markers.
Answers are processed and uploaded as meaningful changesets directly to OpenStreetMap, streamlining the contribution process without manual intervention.
Cons
Available only on Android, with iOS support still in development per sponsorship notes, limiting accessibility for a significant portion of mobile users.
Quests are restricted to simple questions answerable on-site, which excludes advanced mapping tasks like custom tagging or complex geometry edits.
New quests and improvements depend on community contributions and external funding, as seen in the sponsors section, potentially slowing down feature updates.
