Pokémon EV Calculator & Inventory Optimizer

What It Does

This web application helps you plan optimal EV (Effort Value) training for your Pokémon. You enter your desired EV spread, current EVs, and your inventory of Vitamins, Mochi, and Feathers. The app calculates the most efficient way to reach your goals, using your inventory first and optionally simulating purchases with your available funds.

Features

• EV Configuration – set target EVs, input current EVs, parse EV strings, and see warnings if totals exceed 510 or 252 per stat.
• Inventory Management – track quantities of Vitamins, Feathers, and Mochi with quick updates, OCR scanning, and voice input. Inventory is saved in local storage.
• Player Funds – specify League Points and Poké Dollars so the calculator can simulate purchasing Vitamins if needed.
• Optimal Item Calculation – uses items from your inventory first, then determines any purchases required to hit your targets.
• "Subtract Items After Calculation" Toggle – choose whether to deduct used items from your saved inventory.
• Detailed Results – shows overall status, warnings, global EV summary, purchase summary, and per-stat breakdown of items used.
• Export Options – copy the full plan, copy Showdown-style EVs, or download a text or JSON file.
• Responsive and Accessible – designed for both desktop and mobile with keyboard-navigable elements.
