4 Best Pokémon GO IV Checkers in 2025 (Free & Accurate)

If you're serious about catching top-tier Pokémon, you've probably heard of Pokémon GO IV checkers.

These handy tools analyze your Pokémon's potential by reading data from screenshots, things like IVs, max CP, and even PvP rankings. They don't modify your game or break any rules; instead, most of them overlay on your screen (especially on Android) to calculate everything instantly.

You can use them to decide which Pokémon to catch or power up, so you don't have to wait for a Gold or Silver Bottle Cap release.

In this article, I'll focus on the top-rated IV checkers for Pokémon GO and what you need to know about these tools.

IV checker, IV calculator, and IV scanner all point to one thing: tools that help you find out your Pokémon's hidden stats, known as Individual Values (IVs). The different names mainly describe how the tool works:

• A scanner automatically reads your screen to detect a Pokémon's CP, level, and stats.
• A calculator takes your input or game appraisal data to compute the precise IV numbers.
• A checker is a catch-all term that includes both scanners and calculators.

Here's what they can do for you:

• Estimate IVs before catching: Some apps can scan the overworld encounter screen and predict IV ranges, helping you decide whether a Pokémon is worth catching.
• Calculate exact IVs: After you catch one, the calculator reveals its precise IV breakdown so you know which Pokémon to invest Stardust in.
• Assess PvP potential: Many checkers can even rank Pokémon in different PvP leagues, so you'll know if it's Great, Ultra, or Master League-worthy.

In short, whether you call it a checker, calculator, or scanner, it's your best friend for building a stronger Pokémon GO lineup.

#1 AnyTo - Pokémon GO IV Calculator

AnyTo Pokémon GO IV Calculator is a concise website to check your Pokémon's IV. Simply input your Pokémon's CP, HP, Stardust cost, and level, and it will instantly calculate all possible IV combinations at different levels. It's a quick way to estimate how strong your Pokémon can get and whether it's worth powering up.

How to use the AnyTo IV Calculator

Step 1. Go to the website and choose the Pokémon you want to analyze.

Step 2. Enter its CP, HP, and Stardust cost.

Step 3. Click Calculate, and the tool will display all possible IV results and highlight the best combinations for PvE or PvP.

#2 PokeGenie - Pokémon GO IV Checker

Poke Genie remains one of the most trusted Pokémon GO IV checker apps around. It's designed for post-catch appraisals, meaning it helps you understand how good your Pokémon really is after you've caught it. It's accurate and safe, sitting in a gray area but with zero ban risk so far. It gives you:

• The Pokémon's IV percentage and breakdown (Attack, Defense, Stamina).
• PvP league rankings and move recommendations.
• Raid and gym performance metrics.

iOS Users Tip

Poke Genie's info overlay appears as a drop-down notification instead of a floating window, so it's a bit less smooth than Android.

How to use the PokeGenie IV Checker

Step 1. Open Poke Genie and press the "Start Overlay" button.

Step 2. Input your Trainer Level, then allow Poke Genie to appear on top and other permissions.

Step 3. After the app automatically switches to Pokémon GO, go the the Pokémon details page (regular or appraisal), then press the floating button.

#3 Calcy IV - Pokémon GO IV Checker

Calcy IV is a long-time favorite among Pokémon GO Trainers. Unlike most other tools, Calcy IV can estimate a wild Pokémon's IV range and level before you catch it, helping you decide whether to throw that Ultra Ball or just walk away.

It's a screenshot-based IV calculator, meaning it doesn't modify game data, and all of its main features are free (you'll only pay to remove ads).

How to use Calcy IV Checker

Step 1. Open Calcy IV, choose Automatic Scanning or Click-To-Scan, then tap Switch to Game.

Step 2. Allow the app to start recording.

Step 3. Go to the details page of a Pokémon, then tap the floating IV button.

#4 Smart IV - Pokémon GO IV Checker

Smart IV is a younger lineup of Pokémon GO IV checkers, but it's already turning heads. Think of it as a hybrid between a live overlay and a deep appraisal tool with a clean and modern interface, optimized for both Android and iOS.

It displays live IV estimates right as you're catching a Pokémon. After the catch, it gives you a detailed stat breakdown, including IV spreads, potential max CP, and PvP rankings.

How to use Smart IV Checker

Step 1. Open Smart IV, then watch an ad to continue.

Step 2. Follow the prompt to grant access.

Step 3. Go the Pokémon page, and tap on the floating Smart IV button.

Perfect Pokémon, the kind trainers call hundos, have 15/15/15 IVs in Attack, Defense, and Stamina. They're the crème de la crème of your collection. But getting one? It's a real grind. Here's the math:

• Purifying Shadow Pokémon (from Giovanni or Raids): ~2.7% chance
• Trading with a Lucky Friend: ~1.56% chance
• Catching in the wild: ~0.02% (practically winning the lottery)

So, if you're hoping to encounter a hundo in the wild, you'll want every bit of help you can get, and iMyFone AnyTo makes that hunt a lot smarter.

AnyTo's Key Features

• Pokémon GO Search feature lets you snipe Pokémon by IV, CP, Level, and even moves, helping you find hundos without wandering endlessly.
• Live maps for PokéStops, Gyms, Raids, and Routes and 1-click teleportation to the spot, no more burning Remote Raid Passes.
• Unlike most spoofing tools, AnyTo connects via Bluetooth, keeping your spoofing undetected and stable while working smoothly with the official Pokémon GO app.
• It's regularly updated to stay compatible with the latest iOS, Android, and Pokémon GO versions.
• If anything feels off, Discord support team is always around to help troubleshoot and guide.

Here's a quick tech reality check: Pokémon GO's graphics look great, but they're heavy on memory. The game's poor RAM management, especially with the new avatar models, often leads to sudden slowdowns or crashes.

Now add a screen overlay from apps like Calcy IV or Poke Genie on top of that. These overlays float above the game screen, constantly scanning stats and reading screenshots. While super convenient, they also consume extra processing power and RAM, which can push Pokémon GO over the edge.

So if your game suddenly freezes, crashes mid-catch, or your phone starts heating up, those floating widgets might be the culprit. Try clearing them from the background before relaunching the game. Your device and your shiny hunt will thank you.

How are Pokémon GO IVs calculated?

The IV percentage is calculated by adding a Pokémon's three stats (Attack, Defense, Stamina), dividing by 45, then multiplying by 100. For example, a Deoxys with 15/15/14 has an IV of 97.78%.

How do you check IV on Pokémon GO?

You can check IVs manually using Pokémon GO's built-in Appraisal feature. Tap your Pokémon → tap the menu → choose Appraise. Your team leader will rate its stats with stars and bars.

However, if you want exact IV values or want to compare multiple Pokémon quickly, using an IV scanner like AnyTo, Calcy IV, PokeGenie, or Smart IV will give you more detailed and accurate results.

What is a Hundo in Pokémon GO?

“Hundo” is a Pokémon with perfect IVs (15/15/15) — the highest possible stats for Attack, Defense, and Stamina.

Hundos are rare and highly prized because they reach maximum potential when powered up. Many Trainers use IV scanners or tools like AnyTo's Pokémon search feature to help locate and catch these perfect specimens.

Catching a Hundo in Pokémon GO takes patience, luck, and strategy. But with the right tools, you can make that journey smoother and smarter. Pokémon GO IV checkers like AnyTo, Poke Genie, and Calcy IV are your best helpers.

So, if you're serious about improving your gameplay, mastering IVs, and catching that perfect Hundo, pairing a good IV scanner with AnyTo's smart location tools is your best move. After all, in Pokémon GO, knowledge, and location, is power.
