Laced Golf is a golf technology company that builds shoe sensors to read a golfer's alignment and turn it into feedback through an mobile app. Two sensors clip onto a golfer's shoelaces, then light up and vibrate when the golfer is aimed on line. Laced Golf had built an early version of the app in house and came to us to turn it into a stable mobile app and backend ready for real users.
Laced Golf was named one of TIME's Best Inventions of 2026.
Laced Golf had been building fast on their own, so the app arrived with experimental play modes and new updates still coming in. Rather than start over, we built on their existing code and scoped the first release around what beta users needed most. For admin work, Laced Golf's team uses Firebase's built-in console and off-the-shelf dashboards instead of a custom system, so the launch didn't wait on internal tools.
We started by making the existing code safe to build on: fixing the points where the app crashed, moving app data onto a structured cloud database on Firebase and adding crash monitoring. From there we built the full golfer experience on a mobile app. Golfers pair their sensors, set a target line for each club in their bag, record how each shot turned out and track their Shotprint, the app's score for how square they aim and how steady their routine is.
The hardest part was the hardware. Laced Golf's two sensor generations connect the same way over Bluetooth but expect data in different formats, and the earlier sensor ignores data meant for the newer one without any error. We built the light and vibration feedback for both, starting on four early sensors while the newer generation was still being built. Development finished ahead of schedule, and the first version went to beta testers through TestFlight, Apple's testing platform.
Laced Golf went from an early version of their app to a stable, tested mobile app now in the hands of beta customers, ahead of a full launch in 2027. The first release shipped with more features than the original scope. Since then, we've moved on to integrations with other golf platforms. Laced Golf captures what happens before the swing: aim, setup and alignment. Those platforms capture what happens after it. With both connected, golfers will see the full picture, from where they aimed to where the ball went.
