'What's my IQ?' is a casual puzzle and brain-training game developed by Klikapp Games, available exclusively on mobile. You can download it for free from the Google Play Store for Android devices or the App Store for iOS. As a pure mobile app, it's designed for quick sessions on the go, and it has racked up millions of installs across both platforms since its launch. The game is free to download and play, but it's supported by in-app ads that pop up between tests. There are also optional in-app purchases, typically ranging from a couple of dollars to remove ads, to around $10 for bundles that unlock additional test categories or features. It's the kind of app you install for a fun, low-stakes way to challenge yourself.

Playing 'What's my IQ?' is straightforward: you work through a series of short, timed puzzles that test logic, math, pattern recognition, and vocabulary. The best part, in my opinion, is the instant feedback. After a quick 10-15 minute test, you get a score and a breakdown, which feels satisfying. My favorite part is the variety; it doesn't just feel like doing math homework. One minute you're figuring out a sequence of shapes, the next you're solving a quick riddle. It keeps your brain switching gears, which makes the play session feel engaging and less repetitive than some other brain games out there.

Compared to similar games like 'Peak' or 'Lumosity', 'What's my IQ?' is much more casual and accessible. Those other apps often feel like a structured training program with daily workouts and progress tracking. This game is simpler. You just jump in, take a test, and get a number. As a real user, I recommend this app if you're not looking for a serious cognitive training regimen but just want a fun, quick brain teaser during your commute or a break. It's less pressure, more game-like, and honestly, sometimes you just want to see a score without the commitment of a daily training app. For a free download on Google Play, it delivers exactly what it promises: a fast, entertaining IQ-style challenge.

• Quick & Varied Tests 🧩 - The game offers a wide range of puzzle types, from numerical sequences and logical deductions to spatial reasoning and word problems, all packed into short, manageable tests.
• Instant Score Feedback 📊 - Unlike some brain-training apps that focus on long-term progress, this game gives you an immediate IQ estimate and category scores right after completing a test, which is highly gratifying.
• Pure Casual Play 📱 - It stands out from more rigorous competitors by being a pick-up-and-play app with no daily goals or complex progression systems, perfect for a spontaneous mental challenge.

• Accessibility and Simplicity 👍 - The app is incredibly easy to get into. Compared to 'Elevate' or 'CogniFit', which have steeper learning curves, you can download, install, and be taking your first test within minutes.
• Zero Pressure Fun 🎯 - The game doesn't guilt-trip you for missing a day. It's a strength when you just want to play a game, not follow a curriculum. This casual approach is its main appeal over more 'serious' training apps.
• Great for Short Sessions ⏱️ - Each test is the perfect length for a quick break. This makes it a superior time-filler compared to some puzzle games that require longer, uninterrupted focus.

• Ad Interruptions Can Be Frustrating 😕 - The free version is supported by frequent video and banner ads. This can break your concentration more than in ad-free premium apps like the paid version of 'Peak'.
• Lacks Depth and Long-Term Progression 📉 - Unlike 'Lumosity', which tracks your performance over time across various skills, this game feels more like a one-off test generator. There's little sense of building a skill long-term.
• Question Repetition 🔄 - After playing for a while, you'll start to see the same or very similar puzzles reappear. This reduces the challenge and replay value compared to games with larger, constantly updated question banks.
