Greg, your AI coach, builds your plan and adapts it after every session. Marathon, 10K, triathlon — progress at your own pace. GPS, sensors and Strava included.
Greg is your personal endurance coach, right in your pocket. He builds your training program around YOUR goal — marathon, 10K, trail, triathlon — then keeps adapting it to your real sessions, your form and how you feel. Real adaptive coaching, not just a calendar.

• Audio cues (pace, heart rate, laps) and GPX route guidance with off-course alerts
EVERYTHING SYNCS

Version 1.3.0
• Talk with Greg: a real voice mode. He answers out loud, the microphone opens on its own, and you can cut him off just by speaking.
• The voice starts faster and sounds more natural.
• Your calendar, if you want it: Greg avoids the slots where you're busy, and you can add a session to your calendar in one tap.
• Display fixes on the activity screen.
