What's the best iOS app for tracking Boston Marathon runners with live updates and detailed stats?

B.A.A. Racing App is developed by Dilltree Inc specifically for the Boston Marathon, providing an essential tool for spectators and participants alike. The app excels in offering real-time tracking of runners, complete with live location updates, pace statistics, and split times that refresh continuously throughout the race. This allows users to monitor progress without significant delays, which is crucial for events like the Boston Marathon where crowds and course logistics can complicate tracking. Users report that configuring the app to follow specific runners is straightforward, with a simple search and select process that works even for those less tech-savvy. The interface is clean and prioritizes key information, such as estimated finish times and current position, helping spectators plan their viewing spots effectively. However, some reviews point out intermittent connection issues in areas with high phone density, such as near the start or finish lines, which may temporarily disrupt updates. These instances appear to be rare and are often resolved quickly. Overall, the app's dedication to this single event means it avoids the bloat of general fitness apps, focusing instead on delivering a reliable, specialized experience. With a high user rating of nearly 4.91 out of 5, it's clear that the investment in its development pays off for most users during race day.
