The Challenge
NYC has one of the densest speed camera networks in the U.S., and drivers often receive fines without real-time awareness. The primary challenges were both product- and engineering-heavy:
- Building a real-time GPS proximity engine with directional awareness, and user-defined alert distances (50–1,000 ft)
- Ensuring alerts work reliably in the background on iOS (even when minimized or the phone is locked), under Apple’s background execution constraints
- Keeping camera data accurate via automated weekly syncing from third-party camera APIs
- Creating a community contribution flow with an admin review queue to protect data quality
- Implementing Apple In-App Purchase subscriptions with gating, renewal/cancellation flows, and failed-payment handling
- Delivering a reports engine that quantifies value via estimated ticket savings
The Solution
Canadian software agency delivered SLO as a complete end-to-end platform:
- React Native iOS app for drivers with background location support, speed compliance UI, and configurable alerting
- React.js admin portal for managing users, subscriptions, cameras, and moderation
- Node.js/Express + MongoDB backend with JWT-secured APIs and scheduled camera sync jobs
- Integrations across Google Maps SDK, Apple APNS via Firebase, Apple IAP, OAuth providers, and external camera data sources
The system supports two roles:
- Driver (App User): alerts, sessions, reports, subscription management, camera submissions
- Admin (Portal User): user management, subscription monitoring, camera governance, and approvals/rejections for community submissions
Core Platform Features
SLO offers a safety-first feature set designed to help NYC drivers stay aware of speed cameras in real time, from setting personalized alert preferences and running background-enabled driving sessions to tracking alerts, reviewing driving history, and managing premium subscription access.
