## What it is
StreetComplete is an easy-to-use OpenStreetMap editor for Android that finds missing map data nearby and presents it as quest markers on a map. Users answer simple on-site questions, and answers are automatically uploaded as edits to OpenStreetMap under their account.

## Use cases
- contribute to OpenStreetMap without knowing tagging schemes
- survey missing map data like road names while walking around
- update opening hours of nearby shops on site
- map wheelchair accessibility of sidewalks and crossings
- improve OSM data offline with limited data usage
- gamified way to help improve the map in my neighborhood

## When to choose
- you want to contribute to OpenStreetMap as a beginner with no tagging knowledge
- you want to collect on-site survey data for OSM from an Android phone
- you need an offline-capable field mapping app

## When to avoid
- you need a full-featured OSM editor for complex edits like geometry changes
- you are not on Android
- you want to edit OSM data remotely without visiting the location
