If you are a racing enthusiast with an obsession with accurate data and community communication, the RaceChrono Pro is tailor-made for you. It turns your phone into a professional-grade track assistant, and it's super smooth to use and not at all.
To put it bluntly, this APP is a powerful GPS timing and data analysis tool designed specifically for those who love to drive, track runners, and amateur racers. Development team RaceChrono AB is a group of people who are passionate about racing and technology. They blend advanced data analysis with simple design so that you can understand every detail on the track. Functions include real-time timing, data playback, and ability to compare results with friends in the community-its target users are ordinary people who don't want to spend a lot of money but want to have professional equipment: amateur drivers, track day maniacs, and car enthusiasts who simply want to quantify their driving skills and get faster a little bit.
Imagine: you get in the car, press Start, and you can instantly see a huge amount of real-time data-RaceChrono Pro is like giving you a professional racing engineer, and this guy is stuffed in your phone and obedient. Let's take a look at why it makes so many people move.
The core part is its GPS data recording system. This thing captures speed, position, throttle, brakes, and lateral acceleration with terrifying accuracy. It gives you feedback as you circle it. Lap timing is not some kind of silly stopwatch-it accurately records every counting period, allowing you to see at a glance which corner you are driving hard and which place you pee again. Data is displayed in clear, colorful charts, and you no longer have to drive with your head covered. What's even better is that its GPS algorithm is particularly well optimized. Even in indoor parking lots or narrow tracks, it will not be stuck or inaccurate in data like some spicy chicken apps.
Is it not enough to just look at the numbers? RaceChrono Pro can also let you dig it to your bones. You can adjust whatever you want to see, such as G value, tire temperature (just a sensor), engine data (via external plug-ins). There are charts showing details on each lap. You change the opening method or setting, and it will immediately tell you how the effect is. It feels like you have a mini data analysis room, but you don't have to spend tens of thousands of dollars on equipment. Moreover, although the interface has many functions, it is designed quite friendly, allowing even novices to quickly get on the road without those scary thresholds.
The most special thing about RaceChrono Pro is its lively community platform. You can upload lap speeds and scores and compare them with others. You can also synchronize video and data analysis, watch your own lap videos and compare data, and then challenge and roll each other with your group friends. This immediately turned the lonely track day into an arena, and anyone watching it wanted to roll up their sleeves and run two more laps. Unlike some apps that regard data sharing as a bad tail, RaceChrono Pro plays the community clearly, making you feel that this is not a tool, but a digital track-where people share knowledge, encourage each other, and have a little game.
The first time you open it, you will be attracted by the cool interface-the menu design is like a racing dashboard, the icons can be understood at a glance, and the operation is unbelievably smooth. Starting recording, switching views, analyzing data, everything is smooth, obviously optimized for the mobile phone hardware. With so many functions, it may be a bit confusing at first, but don't worry, it has built-in tutorials, and there are also a group of enthusiastic bosses on the Internet to help you get started quickly. And this APP is quite powerful. Even if you use a mid-range mobile phone, it will run steadily and most people can use it.
There are two things about it: first, the accuracy and ultra-low latency of real-time data, and second, the fact that community interaction is done too naturally. Other apps may just let you remember a piece of data. The GPS algorithm of RaceChrono Pro is like it is on, and there is almost no delay. Real-time decision-making on the track depends on it. In addition, sharing data in the community has become a super interesting self-challenge. The atmosphere of competition and friendship coexisting is something you can't find in other apps. This combination of technical hard core + social warmth is really rare in amateur racing apps.
If you really want to track and improve your driving skills seriously and don't want to spend a lot of money on a bunch of professional equipment, the RaceChrono Pro is definitely worth the money. Powerful, user-friendly and active in the community, whether you are a rookie who has just started or an old driver who has traveled many laps, you can find your own fun. Newbies find it not so difficult, but older drivers can also dig out good things from in-depth data analysis. Anyway, want your racing experience to fly? Then bring the RaceChrono Pro, the most reliable co-pilot on every track trip.
It's very simple! Open the App, find "Start a New Session", click, choose a track or create one yourself, and then press the "Start" button to record. It's on the main interface, you can see it at a glance. Give it a try?
There are so many! Things like RaceBox Mini, Qstarz, VBOX, Garmin, etc. will work. Connect to Bluetooth or Wi-Fi and check for the device options in the settings.
This is simple! Open your session record and click the "Analysis" tab. The charts, sector segmentation, and comparison functions are particularly powerful. You can also go to the settings and adjust it to make it more suitable for you.
Wow, there are so many functions! Lap timing, segmented tracking, data recording, video and data display together, and even create your own track! It's all in the main menu, whatever you want.
You just need to connect to the camera or use the built-in recording function of your phone, then add a data overlay layer to the "video", synchronize it, and you can export high-definition video! It's great to share or copy it yourself.
Of course! In the device options in the settings, connect both GPS and OBD-II (both Bluetooth or Wi-Fi will work), so that car performance and positioning data can be captured together, which is super comprehensive!
RaceChrono Pro excels in accurate lap timing, data analysis, and video overlay, especially with external GPS and GoPro. Users praise its comprehensive features and reliable performance on track days. However, some report issues: internal GPS can be inaccurate, and upgrades from free version may lose settings or fail to save videos. While many find it invaluable for improving driving, a few request autostart and faster exports. Overall, a powerful tool for serious enthusiasts, though minor bugs affect consistency.
This works brilliantly with a Garmin Glo for track days. I love the features that let me analyze each sector or add video to the data.
We used RaceChrono Pro (alpha/beta) throughout the VLN season at Nürburgring and were very satisfied. Key observations: an external GPS is essential for accurate data—internal phone GPS works on flat tracks but not at the Ring. The phone's internal video (Samsung S3) exceeded expectations in quality.
Just downloaded an app (haven't used it yet). Is there a setting to use storage on the SD card? My Samsung S7 has 32GB internal storage (almost full), while I have a 128GB SD card.
Love the app, but exporting video and data is too slow. The interface could be cleaner. Data should be pushed down, not covered, when selecting a track.
The free version of Racechrono was so useful that I upgraded just to support the developer. I've tested many Android track timers, and Racechrono is clearly the best. It has never crashed or failed me. I use its export files to create video overlays. It has improved my driving both in real-time and after reviewing results.
