About pokemons.io

What is pokemons.io?

pokemons.io is a free Pokémon calculator hub. We host 12 interactive tools (damage calc, type chart, team builder, IV calc, EV planner, breeding calc, and more), a complete 1,025-Pokémon Pokédex, 25 hand-written competitive build guides, and 456 individual move pages. Everything is free, no signup, no ads gating tools.

Is this an official Pokémon site?

No. pokemons.io is a fan-made resource. We are not affiliated with, endorsed by, or sponsored by Nintendo, Game Freak, Creatures Inc., or The Pokémon Company. All Pokémon trademarks belong to their respective owners. See our About page for the full disclaimer.

Do you charge for anything?

No. Every tool, calculator, and page is free. The site is supported entirely by display advertising. We will never charge for premium features, sell subscriptions, or paywall any tool.

Are my calculations saved anywhere?

No. Every calculator runs entirely in your browser — your inputs (Pokémon picked, IVs, EVs, etc.) never leave your device. Some tools (like the team builder) use browser localStorage to save your work between visits, but that data is local-only.

Calculator accuracy

How accurate are your calculators?

Our damage calculator uses the exact Gen 9 damage formula validated against Smogon's open-source damage-calc library and in-game testing. Stat formulas match the games exactly. See our methodology page for the full breakdown including known limitations.

Why does my calculation differ from Pokémon Showdown?

Most common cause: missing modifiers (weather, terrain, items, abilities, screens). Double-check that all conditions are set. If you're still off, we may not be modeling a rare interaction (Triple Axel progressive damage, Beat Up, etc.). For those edge cases, use Showdown's calc directly.

Which generation do your formulas use?

All current formulas are Gen 9 (Scarlet/Violet + Indigo Disk DLC). Stat formula and type chart are unchanged from Gen 6 onwards, so the same calculators work for older generations with minor caveats (Hidden Power doesn't exist in Gen 8+, snow replaced hail in Gen 9, etc.).

Are abilities and items factored in?

Yes. The damage calculator has explicit checkboxes for Tera, STAB, crit, doubles spread, weather, and the most-common offensive items (Life Orb, Choice Band/Specs, Expert Belt, Muscle Band). Ability-based modifiers like Adaptability, Tinted Lens, and Sword of Ruin are accounted for in the build pages and need manual application in the damage calc itself.

Pokémon GO

Do your Pokémon GO calculators use real Niantic data?

Yes. Our CP, IV, and league rankings use Niantic's published CPM (Combat Power Multiplier) table and the same IV ranges Niantic uses (0-15 per stat, not 0-31 like main series). The full CPM curve from level 1 to level 51 (Best Buddy boost) is hardcoded.

Are the GO best-moveset recommendations current?

Yes — last updated May 2026. Recommendations are based on community consensus (GamePress, PvPoke) and Niantic's most recent move rebalances. We update when major patches change the meta.

Do you have a CP calculator for every Pokémon?

Yes. The generic CP calculator works for any Pokémon — just enter the base stats (HP, Atk, Def), IVs (0-15), and level. The CP formula is the same for every species.

Competitive play

Are your competitive builds tier-list accurate?

Builds are hand-written by Showdown OU and VGC Regional-level players. Each one specifies the format it was tested in (Gen 9 OU or VGC Regulation H). Tiers shift monthly — we re-validate the top 25 builds quarterly.

Do you support Showdown export?

Yes. Every build page has a Showdown-format export block you can copy-paste directly into Showdown's teambuilder. The team builder tool generates Showdown-format export as you assemble.

What about VGC Regulation X / future formats?

We update Regulation labels when Pokémon Company announces format changes. Currently focused on Reg H + Smogon OU. For older Regs (Reg D, F, G), the underlying mechanics are identical so builds still work — just the legality changes.

Pokédex & data

How many Pokémon are in your database?

1,025 — every Pokémon through Gen 9 (Indigo Disk DLC). Each has its own dex page with base stats, type matchups, defensive weakness chart, and links to relevant tools. ~870 have sprite images; the rest use first-letter monogram placeholders.

Why doesn't [specific Pokémon] have abilities listed?

We have abilities for the ~100 most competitively-relevant Pokémon hand-curated. The remaining ~900 don't have abilities listed because our primary ability dataset is Gen 9 (Paldean dex). We're working on backfilling all generations — see the changelog for status.

Are stats accurate for older generations?

Base stats are the most recent in-game values. If a Pokémon got a base stat buff/nerf in a recent generation (e.g., Pikachu's base SpD went from 40 to 50 in Gen 6), we use the current value. For historical accuracy on older gens, cross-reference Bulbapedia.

Site & technical

Do you have a mobile app?

No. pokemons.io is a mobile-first website — it works on any phone, tablet, or desktop browser. No installation needed. The site is built as a static site, so it loads instantly and works offline once the page is cached.

Does the site work offline?

Once you've loaded a page, the calculators on it work offline (everything runs in your browser). Navigation between pages requires connectivity. We're considering a Progressive Web App (PWA) version for full offline support.

Can I link to specific calculator inputs?

Not yet — but we're adding URL-encoded inputs as a feature so you can share a specific calc setup (e.g., 'Garchomp Earthquake vs. Tinkaton at 252+ EVs') with one link. Coming soon.

Where can I report bugs?
