How it works
Three steps to race day
01
Pick your avatar
Choose a runner who's yours. They start at the first station and earn every new pose as your training stacks up.
02
Invite your partner
Send a code. Your plan, race date and progress sync between both phones. Poke them when they're slacking, send props when they're not.
03
Grow together
Both avatars climb the course side by side. Hit a new tier and you both get the moment.
Inside the app
Built for two, not bolted on
Roxy says
- “Go hard today. You're ready.”
- “Ease off: 4 × 1 km, not 6.”
- “Rower taken? Swap in the SkiErg.”
- “Recovery day. Sleep wins.”
Roxy, your AI coach
Roxy reads your check-in and your plan, then makes the day's call.

Questions, answered
Does my partner need their own subscription?
No. One subscription covers both partners. You each use RoxDuo on your own iPhone, linked together.
When does RoxDuo launch?
Soon, on iOS first. Join the waitlist and we'll email you when it's live — waitlist members get access first.
Is there an Android version?
Not at launch. We're starting with iPhone. Tell us on the waitlist if you're on Android so we know how many of you there are.
I don't have a doubles partner yet. Can I still join?
Yes. You can start training on your own and invite a partner later. On the waitlist you can also opt in to being introduced to someone racing the same event.
Do I need an Apple Watch?
No. The plan, avatars, Partners tab and Roxy work without one. Apple Health adds sleep and recovery insights if you have the data.
What happens to my Apple Health data?
It's read on your phone to show your recovery and stays there — we don't store it on our servers. Roxy only uses it if you switch that on.
Is RoxDuo made by HYROX?
No. RoxDuo is an independent training app for people racing HYROX Doubles. It isn't affiliated with or endorsed by HYROX.
