NYRR Racing is a free Android app developed by RTRT.me in the Lifestyle category, specifically for Health & Fitness. This app provides real-time runner tracking for NYRR in-person races and is perfect for both participants and spectators. With NYRR Racing, participants can access an interactive course map, see live leaderboards, and check their times, paces, estimates, and places in real-time. Spectators can use the app to track multiple participants at the same time, get push notifications as progress is made on the course, and share updates on social media. The app also provides event info and messaging, making it a one-stop-shop for everything related to NYRR races.

The app's live course tracking feature is a standout, allowing participants and spectators to see the exact location of runners on the course. Additionally, the app's push notifications keep everyone up-to-date with progress made on the course. However, it's worth noting that not all NYRR races are available on the app, and some included events may not use all features. It's also important to keep in mind that continued use of GPS running in the background can dramatically decrease battery life.
