## Description

"Stop guessing. Start calculating with mathematical precision."

Most gacha calculators rely on Monte Carlo simulations—random 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.

■ 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 you’ll gain from character banners to plan your next 6-star weapon.

■ 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.

■ 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.

■ Roadmap: Coming Soon Full support for the following titles is coming soon:

Genshin Impact

Goddess of Victory: NIKKE

Honkai: Star Rail

Wuthering Waves

■ 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.
