About

How IV Calc turns published game mechanics into transparent, independent calculation tools.

What this site does

IV Calc is an independent calculator library for people checking creature stats, training plans, matchup coverage, battle damage, Speed order, experience curves, and Pokémon GO appraisal arithmetic. It is not affiliated with or endorsed by the game publishers. The name, navigation, logo, and domain use the IV Calc identity; franchise names appear in page copy only to identify the games whose factual mechanics are being discussed.

The site is run as a small independent reference project rather than a community, a wiki, or a competitive team service. There is no account system, no login, and nothing to subscribe to. Every tool answers one question with visible arithmetic, and every page states the generation or game mode it supports so a result is never quietly applied to rules it was not written for.

Data and editorial method

Every calculation runs locally from formulas and reviewed data committed with the site. The species snapshot stores National Pokédex number, name, types, six main-series base stats, growth group, EV yield, and three GO base stats. It contains 255 records used by the tools and data pages. PokeAPI identifiers and reference articles are attributed in each Sources block and in the repository data notes.

That snapshot is deliberately a snapshot. It is a dated copy committed to the repository rather than a live request to somebody else’s API, which means the tools keep working when an upstream service is down, a result is reproducible months later, and any change to a base stat is a reviewable edit rather than a silent shift. The trade is that a very recent game update can reach the site later than it reaches a wiki; the Sources block on each page names what was reviewed so you can judge that gap yourself.

Known-answer tests cover stat rounding, IV inference, the full type matrix, team summaries, damage, experience, EV planning, Speed, Hidden Power, GO CP, evolution ratios, and purification. When a formula varies by generation, the page states the supported generation and exposes the simplifying assumptions. Reports should include a page URL, exact shareable query, observed result, expected result, game and generation, and a source that documents the discrepancy.

Shareable results

Calculator inputs are written into the query string, so a copied URL reproduces a scenario exactly — the same species, level, nature, EVs, and IV ranges another person will see. That is what makes a bug report or a team discussion checkable instead of approximate. It also means a link carries whatever you typed, so treat a shared URL as public. The privacy page describes how that state, hosting logs, and analytics are handled.

Original visual work

The handheld shell, stat radar, type swatches, and geometric logo are original SVG and CSS. IV Calc does not ship official artwork, sprites, logos, character illustrations, or copied descriptions. Species names and numeric mechanics are used as factual reference data.
