The Pokémon GO IV checker that reads the appraisal for you

Tap a Pokémon in GO, appraise it, and it is already checked. Nexus Dex reads CP, IVs and moves live from the screen, then tells you whether it is worth keeping. Free on iPhone.

Free: live Pokémon and IV scans cost nothing. Download Nexus Dex on the App Store and check your first Pokémon in under a minute.

What you get on every Pokémon

How it is different from a screenshot IV calculator

Most IV checkers make you take a screenshot, switch apps, and wait. Nexus Dex runs alongside Pokémon GO and reads the appraisal as you make it. The same scanner reads your whole Pokédex, so a checked Pokémon is also a tracked one. If you want the full picture against Poke Genie and Calcy IV, the comparison page is honest about what each does.

Private by design

No game login. No server connection to the game. Scanning uses Apple's on-device Vision framework, and nothing from your screen leaves your phone. Details in the privacy policy.

IV checker FAQ

Does it work while Pokémon GO is open?
Yes. That is the point. Start a scan in Nexus Dex, switch to GO, appraise, and the result is waiting when you switch back.
How accurate is the live read?
It reads the same appraisal bars and CP you see in-game, so it is working from the same information a manual IV calculator would, without the typing.
Can I move over from Poke Genie?
Export your CSV from Poke Genie and import it. Every Pokémon lands in My Pokémon with IVs and league ranks intact.
Is there an Android version?
It's on the way. Leave your email and we'll send the Google Play link the day it lands.
