Free app for Hammerhead Karoo
Your race plan, on your bars.
The plan you'd normally scribble on paper and tape to the stem — full-screen, high-contrast, readable at 40 km/h. Bold the target watts, underline the moment that decides the race.
Type it on your phone in 30 seconds. Change it the night before; your Karoo grabs the latest before you roll out.
