Praxis tracks your training and your food, then uses all of it to coach your next ride.

A MORNING LOOP

1,555ftASCENT

Your readiness state and plan on the phone you already carry.

The morning. Your watch hands over the night: HRV, resting heart rate, sleep. Praxis reads it against your usual range and proactively suggests the plan for the day.

The week. The coach builds it around your rides, runs, and lifts, and moves a session with one tap when the legs or schedule aren't feeling it.

The ride. With numbers big enough to read at 25 mph, it's easy to use as a cycling computer. Add a power meter for deeper insight into your ride. Pair a radar and the edge of the screen glows red as a car closes from behind. Built for any condition: tested at altitude in 100°F heat for 2 hours with minimal battery loss.

The route. Every session shapes you and the journey ahead. Get insights, breakdowns, and connections you might have missed.

The finish. Every ride, run, and lift lands in Apple Health the moment you stop. Then the coach reads it and adjusts what comes next.

The coach. Built on the latest evidence-based coaching principles, your coach won't be a cheerleader, but a deeply insightful guide on your journey and goals.

Set up. Your health data stays on this phone. The coach thinks on Apple's Private Cloud Compute, and Praxis runs no servers of its own.
