Need a hand? Email support@cb-industries.co and we’ll get back to you. Include your iPhone model and iOS version if you’re reporting a bug — it saves a round trip.
Two songs play head-to-head. Tap a side to hear it, then swipe up or down to cast your vote — by default, swipe toward the song you’re choosing (you can flip the direction in Profile → Swipe to vote). Your vote updates each song’s global ranking.
No. DeuxDuel plays 30-second previews available to everyone. An Apple Music subscription only adds the option to save full songs to your library.
A category only publishes a public ranking once enough distinct people have voted in it, and a song only appears once it has enough appearances of its own. This is deliberate — it stops a chart claiming an order that a handful of votes can’t support. See how the ranking works for the full explanation.
Matchups are drawn from the category you’re in, not from your listening history — that’s what keeps the chart from turning into a personalised feed. Use Browse to pick an era or genre you actually care about, and the pool narrows to it.
Not today. DeuxDuel is iPhone-only and requires iOS 17 or later.
Subscribe to DeuxDuel Plus (monthly or annual) or buy Plus Lifetime. Tap the ✦ icon in the app.
On your iPhone: Settings → your name → Subscriptions → DeuxDuel. Cancelling stops future renewals; access continues until the period ends.
Open the paywall and tap “Restore Purchases”.
Tap “Restore Purchases” on the paywall first — that re-syncs your entitlement with Apple. If ads persist after a restart, email support@cb-industries.co with the Apple Account you purchased under and we’ll sort it.
In the app, go to Profile → Delete Account and confirm. This permanently removes your account and all associated data (votes, history, and profile) right away. You can also email support@cb-industries.co from the device’s Apple sign-in and we’ll delete your account and associated data within 30 days.
The short version: your votes, your account identifier, and anonymous usage analytics. The full detail is in the privacy policy.
