Track Genshin Impact, Honkai: Star Rail, Wuthering Waves, Zenless Zone Zero, and Honkai Impact 3rd pulls in one private iPhone app. Pity imports your wish or convene history from screenshots, processes the images on device with Apple's Vision framework, and lets you review every detected pull before saving. No PC is required for screenshot import, no game account login is used, and screenshots are never uploaded. Pity gives you per-banner pity counters, soft-pity highlighting, last 5 star status with won or lost 50:50, manual entry, a resource calculator, Home and Lock Screen widgets, Dynamic Island Live Activity, and Apple Watch support. Free users can track one game, keep 50 wishes of history, import screenshots, and add pulls manually. Pro Single Game is a lifetime unlock for unlimited history, notifications, and spend tracking for one game. Pro All Games is a lifetime unlock for all supported games, the cross-game dashboard, and luck percentile. There are no subscriptions and no trials. Pity is a statistics tracker for pulls you already made. It does not enable, simulate, facilitate, or encourage spending, and optional spend figures are estimates controlled by the user.

Verdict
The clearest difference is in-app purchases: Gacha Calc at none against Pity's 2. Gacha Calc also leads on update cadence (daily vs fortnightly) and iOS requirement (14.0.0 vs 17.0). Pity's advantage is ads (none vs shown). On price and device support there is nothing between them.
