RaceTime is an app concept I designed to bring the excitement of racing to anyone, anywhere. The idea is simple — use your device’s camera to capture lap times and track performance metrics for backyard or local park race sessions with friends.
My goal with RaceTime was to make timing and performance tracking accessible and fun, without the need for expensive equipment or complex setups. It’s meant to encourage friendly competition, provide instant feedback, and help newcomers to the racing scene see how they’re improving over time — both in their driving and in their vehicles’ performance.
Ultimately, I wanted RaceTime to make a challenging hobby feel easy to enjoy. Whether it’s casual backyard races or more serious practice sessions, the app concept focuses on bringing people together through the thrill of friendly competition and the shared love of speed.
Here are some shots of my little buggy in action while simulating the use of this app. Simple to set up and silly fun for everyone!
When I reached out to websites and forums to validate my idea and get feedback on the design, the response was overwhelmingly positive. Some people were genuinely excited to try my prototype! I had to let them down gently, explaining that it was just a clickable Figma design at this stage. Still, many shared the same frustrations that inspired RaceTime—getting into racing can be difficult because practicing with others is tricky. Even if you build your own track with friends, racing without timing devices can be chaotic.
Some concerns were raised about privacy and the accuracy of lap timing. To address privacy, I included an option to disable screenshots entirely. The app never records video—only a single frame when a lap is detected. As for accuracy, I found that reliable lap timing is definitely possible. For example, an app called Mini4 Lap Timer on iOS already does this well, though it struggles in low light. That gave me confidence that the technology exists—I just wanted to take it further. RaceTime is designed to offer more features, more flexibility, and a smoother experience than anything I’ve seen available.
I also explored how users could differentiate racers more easily. If screenshots are captured when the vehicle passes near the center of the frame, users could identify racers manually and recalculate lap data for each one. That would make it possible to see standings and compare performance between racers after a session.
Personally, I’ve simulated RaceTime by combining a simple lap timer with ChatGPT to handle the math—and it made practicing way more fun than just driving aimlessly. Normally, I’d set up a small track, try to go fast, and maybe count crashes, but that doesn’t really measure improvement.
RaceTime fills a gap for people who don’t live near a track or have access to formal racing events. It could be used for RC racing, BMX, fitness training, obstacle courses, or even dog runs. While my inspiration came from my love of racing, the concept could easily adapt to all kinds of activities. I like to imagine what others could do with it—and how they’d make RaceTime their own.
