Common questions
What devices does RUHN support?
RUHN requires an iPhone running iOS 17 or later. Apple Watch is not required but enhances heart rate zone accuracy when paired.
Does RUHN work on a treadmill?
Yes. Connect a Bluetooth heart rate monitor (Polar, Garmin, Wahoo, COROS, Samsung, Scosche) and RUHN uses heart rate for effort tier classification indoors. Without a heart rate monitor, tier is locked to Low.
Does RUHN require an internet connection?
No. All voice audio is rendered in advance and bundled with the app. Zero network calls are made during missions. Route planning uses a brief network request before you start, but the mission itself is entirely offline.
Where is my data stored?
Everything stays on your device by default. RUHN has no user accounts. Two optional features can send data off your device, only if you turn them on: Signal Memory syncs your progression to your own private iCloud, and Signal Uplink sends a derived summary of a finished run so D.I.A.N.A. can compose an extended analysis. See our privacy policy for details.
How do I reset my progress?
Open Settings (gear icon on the Dashboard) and scroll to the Reset section. You can independently reset rank data, onboarding state, calibration, and training plans.
Can I use my own music?
Yes. RUHN supports Apple Music and any external audio app (Spotify, YouTube Music, podcasts, radio). D.I.A.N.A. automatically lowers external audio when she speaks.
