User Reviews
Great app! I had issues with racebox not connecting. But learned that you need to disconnect the other apps. Works great!!
3月8日にサポートに問い合わせた時点で、「あと2週間程度で対応したアップデートを提供できる！」という返事をもらったので、アップストアの審査も考慮して、今月末かな？と期待大です！
My viewpoint is coming from some who is a cone dodger, not a track person, but I think if anything the app will work better for track usage. My 3 suggestions to go from a 4 start to 5 star app would be: 1) let me install the iPad version on my Mac so that I can review data on my much larger external monitor. 2) allow me to play back the run in slow motion (1/2 speed, or 1/4 speed for example). Inputs in AutoX are so fast that I’m always trying to pan through the run in slow motion to digest the elements and what the car is doing. Can’t do it in real time. 3) this may not be an iPad problem but at least on my phone the map by default is too zoomed out. I know autoX courses are smaller than tracks but the map by default is too far zoomed out on my phone to even see where in the run I’m looking at. I always need to zoom all the way in before I can look at any data, otherwise I have no context for where in the run I am.
it utterly lacks about half the most features you’d expect out of a $20 app like this.
5 stars for the features, 1 for UI. The app is supposed to be used in rough environment with bright sky background and touches in gloves, so why the main UI controls are so bleak and small? I’ve lost my data multiple times because of these UI issues. Plz hire a designer and make the app at least usable from UX perspective
exported video bitrate too low
I recorded a 4K 60fps video with built in recording feature, and could previous it normally. But when exporting the video with data overlay, I could only get a 4K video with 16.67fps. There was no available settings for that.
goproは11までしかremote controlが対応していません。12と13の対応を早急にお願い致します。
メールも無視。
スタートゴールの位置が動かず設定できません。
I am Japanese and use this app in Japan. Please tell me how to set it up. On the session screen,I tried to compare the best rap with other rap. On a map,two small arrows move along the line. Despite the difference between the best rap time and the time being compared to, two small arrows end at the same time. I want to set the small arrows to move at each time. Another person seems to be able to set it up like that on iPad mini.
GoPro5を2つ同時に繋げようとすると競合するため1つを無効化しないといけません。 GoPro5と6とかみたく、全て別バージョンのGoProを使わないといけないのはいただけません
