AltSide
NYC

A mobile app for drivers who park on the street in New York City. It shows which nearby spots can stay parked longest before the next street sweep, remembers where each car is parked and sends a reminder before the sweep. It works offline, with no account.

Specification

From the project README
What

New York City sweeps each street on fixed days and times, and a car parked there during the sweep gets a ticket. AltSide shows the spots around you and how long each one can stay before its next sweep, saves where each car is parked and sends a reminder before that sweep. It counts the NYC holiday suspensions.

Who it is for

Drivers who park on the street in New York City. The parking signs and the holiday calendar ship inside the app, so it works with no connection and no account.

Built with

Expo and React Native in TypeScript, with Mapbox maps.

Where

iOS and Android, through the App Store and Google Play. The app's page is on oneradstudio.com.

Privacy

All personal data stays on your device. No location history, vehicle information or personal data is stored on external servers. There is no backend.
