Someone should rethink the camera orientation lock thing, and separate record button. Putting it in. Settings where it records video when you click record session is obvious fix. ### 3/5 — Great…when the UX doesn’t get in your way *2026-06-25, version 10.2.4* I’ve used this app for 2 separate track days now. While I’ve found the overall quality of data, export options and GPS tracking to be solid, the UX is a complete nightmare, especially given that this is a paid $20 app. I had multiple sessions not record the video feed because the UX is not very clear about when the camera is active vs when it’s not. Not to mention, the whole landscape vs portrait orientation lock just adds more confusion because it can end up with the camera orientation locked but the overlay changed. Also why are both the “STOP” and “START” buttons shown as red? I literally missed my best session because there is no easy visual cue for whether the video feed is being recorded or not. This could be as simple as giving an option in the settings to always turns on and record camera feed when recording a session. I was originally going to give it 4 stars instead of 3 because when it works, it is genuinely good. But someone else also brought up the UX issue and the dev response was “it’s a tool not eye candy”. As a dev myself, this is not a good sign. I understand that when your work is up for public comments, it is not easy to see it get criticized, oftentimes unfairly. But the bad UX is a serious issue for an app that’s used as a tool for track days, where we don’t have time to fiddle about as our session is about to start. There are far more important things like safety measures to worry about rather than try to figure out if the app is recording the video feed or not ### 2/5 — 定位数据不准 *2026-04-11* 最新版用谷歌地图一样定位偏移，完全没法用？ ### 4/5 — 大疆！DJI *2026-03-27* 希望能支持大疆的运动相机做为摄影机，gopro已经out啦 ### 4/5 — RaceChronon is my preferred datalogger on IOS *2026-03-07, version 10.0.0* 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. ### 3/5 — Excellent features, poor UI *2025-12-21, version 9.1.3* 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 ### 4/5 — 请支持carplay音乐播放 *2025-11-26* 想用做日常行车记录仪，但在手机开始录视频时，音乐播放就自动停止了😭 ### 4/5 — Carplay *2025-11-14, version 9.1.3* I hope can use in carplay … ### 3/5 — 地图偏移 *2025-10-19* iOS和Android两个版本我都买了，9.1.3仍然在中国大陆存在偏移问题且无法解决 ### 4/5 — Adattate le insta 360 *2025-07-24, version 9.0.2* App ottima peccato con si possono collegare solo le go pro ### 3/5 — 黑屏 Bug *2025-06-24* 倒入 GoPro 13 数据，在赛道界面可读取画面、速度等数据，可是导出后为黑屏，有声音，望回复。 ### 5/5 — Awesome App *2025-06-23, version 9.0.2* Works great, easy to navigate and has really helped to lower my lap times. Used on an IPhone 6 on a motorcycle ### 5/5 — Feature Required：video exporting bitrate setting *2025-05-31, version 9.0.2* exported video bitrate too low ### 5/5 — The best! *2025-05-10, version 9.0.2* The best in the market ### 2/5 — Почему перестало накладываться телеметрия на видео? *2024-12-24* На выгружаемое видео вместо телеметрии просто появляются полосы . Как исправить? **Developer response:** Videos are still overlayed by data, please check our tutorial on exporting video. ## Most critical reviews (10 lowest-rated) ### 1/5 — Missing features *2026-02-24, version 9.1.3* it utterly lacks about half the most features you’d expect out of a $20 app like this. ### 1/5 — Ужасно *2025-05-12* С racebox работает ужасно! Уж не знаю кто там виноват. ### 1/5 — Not compatible to GoPro 13 *2025-03-11, version 8.0.9* gps lap time data from GoPro 13 can not be recognized by the app ,and idk why ### 1/5 — GoPro 13… import not working *2025-01-27* Need to use with my goPro 13 black… but the import function in the racechrono is not working. **Developer response:** Fixed in the new beta, released soon to public ### 1/5 — Does not work *2024-12-07, version 8.0.9* Can’t import files through photo app as it keeps saying import failed. Using a GoPro 13, gps enabled. ### 1/5 — サポートが全く機能していない *2024-09-16* メールも無視。 **Developer response:** Partly due to language barrier, I do not fully understand the issue with the comparison. Please contact the RaceChrono support, and once you receive a reply from us, you can send some screenshots to illustrate what is going on. Maybe we can then instruct you how to do what you want. ### 1/5 — 使い方がわからない *2024-09-15* スタートゴールの位置が動かず設定できません。 ### 1/5 — Really not happy *2024-05-01, version 8.0.9* I have a DJI action 3 and there is ZERO options from what I can see to import the data even using the gps adapter Maybe I’m wrong, but I’d love to know ### 1/5 — 블루투스 GPS 등록이 안됩니다. *2024-01-08* 안드로이드 버전은 블루투스 GPS 등록 기능으로 외부GPS 등록하여 사용하고 있었는데 아이폰으로 바꾸면서 앱 새로 구입해서 사용하고 있는데,사전에 등록된 GPS외 블루투스GPS를 등록하는 메뉴가 없네요. 아이폰도 안드로이드와 동일하게 블루투스 GPS 등록하려면 어떻게 해야하는가요? 불가능하면 앱 구입한 의미가 없어서 환불 요청합니다 ### 1/5 — 外部GPS *2023-12-16* 説明にはGARMIN GLO対応とありますが、設定の中にはGARMIN GLOがありません。 使用しているのはios版です。 GARMIN GLOの使い方教えて下さい。 ## Most praised reviews (10 highest-rated) ### 5/5 — Awesome !! *2026-06-19, version 10.2.3* Simply the best ### 5/5 — Racebox mini is connecting now *2026-06-15, version 10.2.2* Great app! I had issues with racebox not connecting. But learned that you need to disconnect the other apps. Works great!! ### 5/5 — App incrível *2026-06-05* Simplesmente incrível e completo telemetria completa ### 5/5 — Profissional *2026-05-23* Aplicativo excelente para utilização com receptor de GPS externo. Utilizo com o JGPS da @DriveCopilot fabricado no Brasil e os dados ficam perfeitos! ### 5/5 — gopro13への対応 *2026-03-24* 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！ ### 5/5 — App incrível *2026-01-10* Simplesmente incrível e completo ### 5/5 — Hope to support multi-frame message *2025-12-03* Very good customization function. Only one update I want is to support multi-frame message. When I request a PID, if the response is a multi-frame message, and the first frame is correct, it will not send a flow control (such as 0x30 00 00) to controller and cause the multi-frame message aborted ### 5/5 — CarPlay *2025-11-13* This app is very convenient; I use it for recording on my phone with the RaceBoxMini and an OBDII adapter. Please add CarPlay support, I really miss that feature. **Developer response:** We have a CarPlay prototype, but it needs some more work before it's good enough for our standards. ### 5/5 — Excelente *2025-10-01, version 9.1.3* Aplicativo excelente para utilização com receptor GPS externo. Utilizo com o JGPS da @DriveCopilot fabricado no Brasil e os dados ficam perfeitos! ### 5/5 — Как я жил без этого? *2025-09-19* Данное приложение - прекрасный комбайн для автоспорта. Использую в паре с RaceBox для отсчета времени круга. И vGate iCar 2 для мониторинга параметров автомобиля. С последним у меня есть предложение. Чтобы можно было в один клик загрузить имеющиеся данные по obd2-датчикам/CAN у сообщества. Поиск информации по форумам и отладка данных занимают много времени, хотя точно такая же работа была проведена другими пользователями. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
