In the past 10+ years, I tried various lap timers including Harry’s Lap Timer, AIM Solo 2 DL, and Garmin Catalyst. They each had pros and cons in terms usability, dependency on external devices, accuracy, and maybe most importantly availability. My use case is very simple. I want to be able to time my laps fairly accurately and review some basic data post track day, such as min/max speeds at each corner. In other words, I don’t (want to) spend hours on data analysis after each track day. Very simple ask right? Well… All of those lap timers I mentioned earlier let me down at track at least once. Either the device wouldn’t power on or it couldn’t get a gps signal or find the track. When I saw that PB Buddy offers similar live timing as Catalyst with color coded time deltas during a session and optimal time, I decided to give it a try. Because why not? Much less bulky, no cables needed, no camera required, just need my iphone and racebox mini. Super lightweight and easy to use setup. I’ve used it in multiple track days since last year and I love it. It’s continuously getting better and I’m sure there is a lot more to come. I personally cannot wait for some in-app data analysis even if it means just starting with some basic things like min/max speeds per lap per corner etc. maybe displayed on a map. Anyway… Just give it a try, you won’t regret it!

PB buddy is my favorite lap timer for getting a sense for where I can improve while out driving on track. The color system makes it easy to tell how much you’ve improved or fallen behind at a glance and the sector display does a nice job of showing where on track you netted that gain or loss. This simple feedback helps me actively improve my technique while I’m driving. I’ve found that other timers tend to require keeping mental tabs on how much a predictive timer changes each corner, which is quite distracting. In contrast, the color feedback from PB buddy is both immediate and easy to parse at a glance. It’s just the right amount of information to be helpful while allowing you to focus the majority of your attention on driving. Works great with racerender too.

The predictive lap timing is genuinely useful, and the color-coded sector system makes it immediately clear where you’re gaining or losing time in real time. No digging through data after the session — you know exactly what’s happening while it’s happening.The ability to break sectors down into smaller chunks is a big deal for serious development work. It lets you get granular on specific corners rather than just looking at broad splits.Whether you’re just getting started in HPDE or competing at a high level, this app meets you where you’re at. I’ve used it to secure multiple P1s in California N Cup and podiums in NASA Time Trials — it’s even replaced my Garmin Catalyst entirely. That should say enough.

This app has been a game changer.The color gradient and sector splits allow you to very very quickly understand if you’re on a flyer and where you are losing or gaining time. It works so well in your peripheral compared to other lap times (cough cough aim) and I found myself getting immediate feedback on my lines/braking zones. This means immediate adjustments during your session rather than having to review the data in the hot pits. Cannot recommend PB Buddy enough and highly encourage everyone to give it a try at their next HPDE or TA event.
