Multi-system fatigue model.
Independent tracking of muscle load, impact, cardiovascular strain and neuromuscular stress — so you can train one system while another recovers.
Your training decision engine.
Taper builds a comprehensive profile from your goals, training and recovery data, and creates a custom, adaptive plan that fits around you.
More than a dashboard.
Connect Apple Health, Strava, Garmin, Whoop, Oura and other wearables to bring your training and recovery data into one place. Taper uses it to adjust today's session and flag when recovery says ease off.
A training plan that fits around you
Not the other way around. Taper builds and adapts your plan to your life, your goals, your fatigue and your schedule. Taper easily handles complicated schedules, multiple goals, strength + endurance, holidays, and injuries.
Automatic post-session debrief.
Get in-depth analysis from your virtual coach immediately after every workout. Dive into the stats with the context of what it all means, what was good and where to improve.
Answers, the moment you need them.
Taper is always there to help explain, plan or make a decision. Unsure if you should train or rest, how to approach a holiday, or how much you should train during taper week – Taper tells you what to do and why.

The hardest part of race week isn't the work — it's not undoing it. Taper holds the line every day, with the reasoning that keeps you honest.
I know today's session looks too easy. It's not. Your CTL is right where it needs to be and freshness is still climbing. One more bullet in the chamber for Sunday.

Common questions.
What devices does Taper read from?
Strava, Garmin, Whoop and Apple Health. If a device exports a full activity stream, Taper picks it up the same morning.
How is this different from a recovery score?
Recovery scores give you one number. Taper tracks muscle, impact, cardio and neuromuscular fatigue independently — then turns that into a concrete decision, with the reasoning attached.
What sports does it support?
Run, ride, swim, strength and hybrid training. Built around serious endurance and strength athletes — triathletes, cyclists, runners, lifters, ultra and Hyrox.
What about privacy?
Your training data stays yours. We never sell it, never share it, and you can export or delete everything from settings at any time.
When does it ship?
Private beta with a small group right now. Public launch in 2026 — join the list and we'll bring you in as cohorts open up.
How much does it cost?
Free during beta. Pricing will be announced at launch — early beta users get a discounted rate.
Can I connect to Claude or ChatGPT?
Yes. Taper has an MCP server — connect it to Claude, ChatGPT or any MCP-compatible client and query your training data directly.

Do I need an Apple Watch?
Taper works best with Apple Watch, but planned workouts can also be pushed to Garmin devices.
What if I don't have a recovery device?
No problem. Taper builds your fatigue model from training load alone — HRV and sleep data from Whoop or Oura adds another layer, but you get a complete plan either way.
