City officials say about 67,000 neighborhood-related issues have been resolved in two years through the Improve Detroit cellphone application.
More than 8,900 illegal dumping complaints and 4,200 abandoned vehicles have been addressed since the app was launched in April 2015.
The city also helped with close to 5,900 pothole complaints and about 5,400 tree issues.
An electronic service request is generated each time an issue is reported and departments track how long it takes to respond.
Mayor Mike Duggan says Monday in a news release that the approach "to addressing citizen concerns has really transformed how the city delivers its most basic services to its residents."
The app is available free from Google Play and Apple Store.
