The ability to track a racer and know that they are still on course and safe is priceless. But now with the add of groups and a social element this app is essentially strava & Instagram combined. ### 1/5 — What does this do, and how does it work? *2020-09-25, version 1.2* The interface is anything but intuitive, and it’s purpose and value proposition are not clear at all. Was this designed for an iPhone 4? ### 5/5 — Awesome *2020-09-12, version 1.2* This app is amazing I highly recommend it to anyone who is athletic or if u want to just have fun ### 5/5 — Amazing!! *2020-09-04, version 1.2* I love that I can watch my husband race when I’m at home with our new baby. Can’t wait to see what features they add next. ### 2/5 — Help please *2020-08-17, version 1.2* I downloaded the app for the virtual seahorse race per utube video. I put in race and race ID number and clicked finish when done but the app does not register my finish. ### 5/5 — 5 stars! *2020-07-25, version 1.0* This is such a great app idea!! My husband is a dirt bike racer and I always am nervous he will get lost. This app lets me know exactly where he is at all times! I also love that I can see how well he’s doing in a race even if I can’t physically see him the whole time. Great work! ### 5/5 — Fun to use *2020-07-25, version 1.0* Exciting to be able to able to track from a distance! Great app ### 5/5 — Highly recommend *2020-07-24, version 1.0* Great app! 10/10 ### 5/5 — Amazing app!! *2020-07-24, version 1.0* I love how this app gives you the option to see the progress of people during races. I always get nervous when my sister participated in really long races and I get scared she will get lost. With this app I feel comfortable knowing that she is safe and doing great in the race.
