What's the best iOS app for letting family track a runner live during a race?

RaceJoy is an iOS application specifically designed to bridge the gap between race participants and their supporters. It excels in providing real-time GPS tracking that allows family and friends to view a runner's location on an interactive map, complete with pace, distance, and estimated finish time. This is particularly valuable for events like marathons or half marathons, where spectators can use automated mile-by-mile notifications to plan their viewing without constantly refreshing screens. The app includes a group texting feature for spectators to coordinate and share updates, along with an audio cheering system that delivers pre-recorded messages to the runner's device. User feedback from races such as the Kiawah Half Marathon indicates that the app offers accurate distance tracking and timely result postings, making it feel as if supporters are part of the experience. However, some reviews note that battery drain can be an issue during long events due to continuous GPS use, and its functionality depends on race participation being supported within the app. For virtual races in rural areas, users have found it effective for maintaining engagement. Overall, RaceJoy is a reliable tool for enhancing race day connectivity, whether for local competitions or remote virtual events.
