Aero is two apps in one: a clean running tracker for athletes, and a complete coaching platform for the people who train them. FOR RUNNERS • Log every run — distance, pace, time, and route — and watch your fitness build. • Keep your streak alive. Aero tracks your consistency so showing up becomes a habit. • A community feed built for runners: share runs, cheer teammates, and follow the athletes who push you. • See your trends. Weekly mileage, pace progression, and personal bests, explained in plain language. • Connect what you already use — sync runs automatically so nothing gets lost. FOR COACHES • Manage your whole roster from one command center — every athlete, every run. • Assign workouts and build training calendars your athletes see instantly. • Spot who's improving and who needs attention with at-a-glance team analytics. • Organize athletes into teams and groups, and invite them with a single code. • Flexible plans that scale with your roster, from a handful of athletes to your entire program. WHY AERO Most run trackers stop at the individual. Most coaching tools ignore the athlete experience. Aero connects both sides — so the run an athlete logs this morning is the data their coach acts on this afternoon. Start free as an athlete. Coaches subscribe to unlock the full team-coaching toolkit. — Subscription details — Aero Coach is offered as monthly and annual auto-renewable subscriptions (Coach 25, Coach 75, and Coach Unlimited tiers).
