R-navi makes cheering at running events easier and more fun! When your family or friends are running a race, you probably wonder, "Where are they now?" or "When will they pass by?" But waiting by the roadside without knowing can be tough. With R-navi, you can see the runner's predicted location on a map based on official race timing data. You'll know roughly how many minutes it'll take for them to reach your spot –– so you can cheer at just the right moment! Can't make it to the course? No problem! You can send supportive messages or tap the virtual drum to cheer from anywhere. Runners can also enjoy the app by reviewing their race results and sending thank-you messages to their supporters. (If you registered for the race through RUNNET, you'll get access to even more features!) Now supporting around 100 races per year — Join in and make cheering (and being cheered for) more special than ever! Tablet support is not guaranteed.

Verdict
The clearest difference is ads: R at none against 潮目's shown. R also leads on update cadence (fortnightly vs every 3 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
