Frequently asked questions
Do I need to create an account?
Yes, in 30 seconds: your email (you get a 6-digit code, no password) or “Continue with Apple.” That’s how you get your account back if you change iPhones.
Which devices does RNDS run on?
iPhone with iOS 26 or later, and Apple Watch with watchOS 26. The app is available in English and French.
How do I connect my Apple Watch?
Install RNDS on your watch from the Watch app on your iPhone. There’s nothing to connect in RNDS: the app opens on its own on the watch when you start the timer, with heart rate, calories and a vibration every round.
My watch isn’t tracking my session
Check three things: RNDS is installed on the watch; the Apple Watch option is on in Settings › Health and sensors; Health access is allowed (same screen, “Allow access to Health”). Keep the watch on your wrist and unlocked, then start the timer again from your iPhone.
Does RNDS work without an Apple Watch?
Yes, everything works with just your iPhone. To see your heart rate during a session, you need an Apple Watch or a Bluetooth heart rate strap.
How do I connect RNDS to Apple Health?
In RNDS: Settings › Health and sensors › Allow access to Health. You then pick the data one by one in your iPhone’s Settings: Health › App Access › RNDS. Your sessions are saved there as workouts, along with sleep you log without a watch, your meals, water and weight.
Why does RNDS ask for my location?
To measure the distance, pace and route of your runs. Your location is only used during a run, including with the screen locked, and your route is never sent to our servers. The details are in the privacy policy.
Does the timer keep beeping with the screen locked?
Yes. Beeps and voice keep going when the screen is locked, and the round stays on screen in a Live Activity.
How do I change my username?
In the app: Settings › Profile. If the username is taken, the app tells you as you type.
How do I export my sessions?
In the app: Settings › Data › Export my sessions (CSV). The file opens in Numbers, Excel or Google Sheets.
Where is my data?
Your journal stays on your iPhone and in Health. Only what the social features need is online. It’s all explained in the privacy policy.
How do I report content or block someone?
Tap “…” on a post or a profile, then Report or Block. We review every report within 24 hours.
How do I delete my account?
In the app: Settings › Data › Delete my account. Your online data is erased along with it.
