Common questions
How does training with a partner work?
Start a workout, then tap Add partner. You can add another Duo Fit user, or create a guest profile for someone without an account. Duo Fit then alternates turns between you, and each person's weights, reps and history are recorded completely separately — one workout, individual progress.
Do we each need our own phone?
No. Duo Fit is built for sharing one phone. It tells you whose turn it is after every set, so the phone just gets passed along the bench.
What is a guest profile?
A way to record a training partner who has not signed up. They get their own weights, history and personal bests, kept separate from yours. Please only create one for someone who has agreed to it — see our Privacy Policy.
I'm not getting rest-timer notifications
Duo Fit asks for notification permission the first time you finish a set. If you declined, the timer cannot alert you.
- iPhone: Settings → Duo Fit → Notifications → Allow Notifications.
- Android: Settings → Apps → Duo Fit → Notifications.
On Android, also check that Alarms & reminders is permitted, or battery optimisation can delay the timer.
Does it work offline?
Duo Fit needs a connection to save your sets. If the signal drops mid-workout the app tells you and reconnects on its own as soon as it can. Gyms in basements are the usual culprit — the app will recover, but sets logged while fully offline may need re-entering.
How do I change my weights to pounds?
Duo Fit currently records weights in kilograms. Imperial units are on the list — let us know if you would use them, it helps us prioritise.
I forgot my password
Tap Forgot your password? on the login screen and we will email you a reset link.
How do I delete my account?
Go to Profile → Delete Account. This permanently removes your account, your workout history, your templates, your partner connections and any guest profiles you created. It cannot be undone.
