Screenshots from DiamondOps v1.0; the App Store now has v1.2. Shown on iPhone; DiamondOps runs natively on iPhone and iPad. Data shown for illustration.
DiamondOps for iOS pairs with the full platform at diamondops.gg, which carries the deeper tools: opponent scouting, the Community K-Zone strikeout heatmaps, pack-opening analytics, the items market, Market Segments, the full per-update Diamond Radar track record pages, and the strategy guides. The iOS app covers what you want during a session; the web app is where you plan.
Your account is shared across both — sign in with Apple once and your collection, watchlist and subscription follow you. Full tier breakdown lives on the DiamondOps pricing section.
Do I need the Chrome extension to use the iOS app?
No. Collection sync is built into the iOS app, so it pulls your Diamond Dynasty collection natively. The Chrome extension exists for syncing from a desktop browser — on iPhone or iPad you don’t need it.
Is the iOS app free?
Yes — free to download and free to use. Some advanced features (live prices, advanced signals, unlimited watchlist) are part of DiamondOps Pro, available as an in-app purchase (with Restore Purchases in the app). Your subscription is tied to your DiamondOps account, so it follows you across web and iOS.
Does it need an account?
Yes. DiamondOps uses Sign in with Apple. We don’t store your email address or build an account profile — see the privacy policy for exactly what is and isn’t collected.
What devices does it run on?
iPhone and iPad running iOS 17 or later. The layout adapts to iPad rather than running as a stretched phone app. Android is on the roadmap.
Is my collection data the same on web and iOS?
Yes — both read the same synced collection from your DiamondOps account, so a sync on one shows up on the other.
Free on the App Store for iPhone and iPad. Requires iOS 17 or later.
