IRONMAN Tracker 4+

This app is so awesome and worked like a charm! The estimated locations are a bit ahead of the athletes, which actually works to a spectator's advantage. The only three improvement suggestions: 1) mile markers should be per event, not accumulative. I didn't realize they were accumulative until the run portion and math is not my strong suit to subtract the 112 mile bike miles and the swim miles from the mile marker indicators. :) Mileage reported in the time alerts were by event, so that was good! 2) try to make the map arrows more intelligible when there are loops the athletes have to do. I cross-referenced with each event's map view on the Ironman website, but would've been nice to have the loops better marked in the app. 3) Could you add a "You are here" indicator on the map? I cross-referenced with Google Maps, but having that right in the athlete tracker map would have been even more awesome! But overall...SUCH an improvement from last year's tracker app and I'd recommend it to any spectator! Great job!!

The highlight of this app is the ability to track one or more participants from start to finish, even in the dark! The maps are provided in 2D and 3D modes. Expand the maps and you can see street names as the participant makes turn-by-turn.
In a noisy spectator environment, the Audible notifications as the participant gets through timed check points, is a great plus! This way, one is able to view participant race stats at every stage.
The only downside is that when Internet signal is used by so many spectators at the race venue, tracking can be slow to update. However, if you are familiar enough with the app, you must estimate that your participant is a little further ahead than tracking shows. This enables you to be at a certain vantage place to see and cheer your favorite participants as they pass by.
Overall though, a much appreciated App!

This app is the single best tool to use for planning the day-of spectation of a friend or loved one competing in an Ironman event. You can track multiple athletes both on time-in-event splits and time-of-day splits. These splits and the projected future splits take all of the error and much of the guesswork out of when to position yourself at certain locations, and the app even offers direction to those locations. The only suggestion I could make to improve this app would be for it to take into account the posted Ironman road closures in generating the directions to locations to view each athlete, which could cut out some time consuming navigational cross-referencing. But this app is invaluable and will be my first move in spectating any Ironman henceforth.
