"Stop guessing. Start calculating with mathematical precision." Most gacha calculators rely on Monte Carlo simulationsβrandom trials that only give you an approximation. MirrorLab is different. We use DP-based state space analysis to provide the exact mathematical probability distribution for your pulls. β Day-One Support: Arknights: Endfield Optimized for the complex mechanics of Arknights: Endfield 1.0. Chartered Headhunting: Full implementation of the 120-pull Featured Guarantee (Spark). Arsenal Issue: Accurate modeling of the 80-pull guarantee and the 100/180/260... repeating mileage system. Hybrid Efficiency: Calculate how many Arsenal Tickets youβll gain from character banners to plan your next 6-star weapon. β Why MirrorLab? Precision DP Engine: Forget the variance of Monte Carlo. Our engine uses recursive logic to calculate exact probabilities for every possible outcome. Refund Factor: Factor in 'Certificates' from duplicate pulls to determine your actual cost-per-pull and re-investment efficiency. Architect's Report: Visualize "Worst-Case Scenarios" and "Efficiency Zones" to optimize your spending and avoid mindless pulling. β Two Analysis Modes [Basic Mode] Quick Check Enter base rates, pity counters, and costs. Instantly see the pulls required for 50% / 90% / 99% success. Cost conversion to real-world items (e.g., pizza slices) for better financial perspective. [Pro Mode] Deep Dive Customize and edit Soft Pity curves. Get exact Expected Values and Standard Deviations. View detailed probability distribution histograms. β Roadmap: Coming Soon Full support for the following titles is coming soon: Genshin Impact Goddess of Victory: NIKKE Honkai: Star Rail Wuthering Waves β Key Features Works Offline: No internet required for calculations. Privacy First: No login, no data collection, no unnecessary permissions. Dark/Light Theme: Minimalist 'Mirror' interface designed for focus. Save & Share: Save your custom presets for any banner or game. Calculate before you pull. MirrorLab is the smartest sandbox for your gacha strategy.

A browser that lets you do everything with one hand. HalfMoon Browser is a lightweight web browser specifically designed for one-handed operation on iPhones. It consolidates operations such as back, search, and tab switching into a "dial" accessible from the edge of the screen, aiming for ultimate comfort by allowing you to complete browsing with just your thumb. β Unique dial operation for one-handed use Place your finger on the left or right edge of the screen, and a semi-circular dial will unfold. Simply slide your finger up or down and release to execute the desired function. β’ Back / Forward / Home β’ New Tab / Tab Switch / Close Tab β’ Search / URL Input β’ Add Bookmark β’ Instantly jump to the top/bottom of the page β’ Remove Ads / Share / In-page Search / Auto-scroll / Settings (submenu) Even on larger devices, there's no need to stretch your finger to the center or top of the screen. β Extensive customization to create your own preferences The contents of the dial can be edited at any time from the settings. β’ Add, delete, and rearrange items β’ Swap left and right dials (switch between dominant and non-dominant hands) β’ Two operation modes (hold & release / tap switching) β’ Adjust dial size from 0.8x to 1.8x β’ Adjust haptic feedback intensity β Unprecedentedly powerful ad blocking HalfMoon's ad blocking operates with a three-layer structure. β’ Layer 1: URL filtering blocks over 200 ad-delivery domains at the communication level β’ Layer 2: CSS hiding removes ad containers from the screen β’ Layer 3: Detection bypass (prevents "Please unblock ads" warnings and automatic ad reloads) Furthermore, ads that were not completely blocked by the filter can be manually removed with a single tap from the "Remove Ads" submenu. Hidden selectors are remembered per site, so they will be hidden from the start the next time you open the site. β Other Features β’ Private Browser (Protected by Face ID / Touch ID) β’ Forced Dark Mode (Inverts white background sites to darker display) β’ Super Dark (Darks the entire screen, adjustable from 10-85%) β’ Password Save (Encrypted to Keychain on your device) β’ Site Data / Download / History Management β About the Pro Version Almost all features of HalfMoon Browser are available for free. If you like it, please support us by purchasing the Pro version. The following features are unlocked with a one-time purchase: β’ Expands the number of dial items from 6 to 12 each β’ Favorites exclusive to Private Mode β Privacy This app does not send user browsing data to the developer's servers. History, bookmarks, and passwords are all stored on your device. We do not use analytics tools, crash report SDKs, or collect advertising IDs (IDFA).

Verdict
The clearest difference is in-app purchases: Gacha Architect at none against HalfMoon Browser's 1. Gacha Architect also leads on update cadence (every 2 days vs every 2 weeks) and iOS requirement (13.0 vs 16.0). HalfMoon Browser's advantage is ads (none vs shown). On price and device support there is nothing between them.
