IQ Test, developed by Aliaksandr Uvarau, is a straightforward and focused brain-training app available on Android and iOS. You can find it for free on the Google Play Store and the App Store. It's a pure mobile experience, designed for quick sessions on your phone or tablet. The app has racked up millions of downloads, which speaks to its popularity among people looking for a quick mental workout. It's completely free to download and play, with no annoying in-app ads interrupting your focus. There are in-app purchases, typically ranging from a couple of dollars to maybe ten bucks, which usually unlock additional, more challenging test packs or remove any potential limitations. If you're just curious about your cognitive strengths, the free content is more than enough to get started.

Playing this game is simple: you fire up the app and dive into a series of classic-style IQ puzzles. The best part is its no-nonsense approach. There's no flashy story or complicated meta-game; it's just you and the puzzles, which is honestly refreshing. My favorite part is the variety and the immediate feedback. You'll tackle pattern recognition, logical sequences, spatial reasoning, and math problems. After a test, you get a score and a breakdown, which lets you see where your strengths lie—maybe you're a whiz at spatial puzzles but need to work on your numerical logic. It's that quick hit of mental gymnastics and the clear, quantifiable result that keeps me coming back for another try to beat my previous score.

Compared to other brain games on the Google Play Store, like the more gamified 'Peak' or the vast library of 'Elevate', IQ Test is much more specialized. While those other apps wrap their exercises in progress systems and daily workouts, this app cuts right to the chase. It doesn't try to be a full cognitive training suite; it wants to give you a classic IQ test experience on your phone. I'd recommend this download over others if you're specifically interested in that traditional test format and a quick, uncluttered assessment. If you want a game with long-term progression and varied mini-games, look elsewhere. But if you want to install a simple app, test your logic, and get a score without any fluff, this is a solid choice.

• Classic Puzzle Focus 🧩 - Unlike broader brain trainers, this app zeroes in on the exact types of visual and logical puzzles you'd find in a standard IQ test, offering a purer assessment experience.
• Instant Score & Analysis 📊 - Right after completing a test, you get a numerical score and a simple breakdown of your performance across different puzzle types, which is more immediate and focused than the gradual skill graphs in apps like 'Lumosity'.
• Ad-Free Concentration 🚫 - The complete lack of video or banner ads is a standout feature on mobile. It allows for uninterrupted thinking, a luxury you don't always get in free apps on Google Play.

• Pure & Simple Design ✅ - The interface is clean and gets out of the way. You're solving puzzles within seconds of opening the app, which is much faster to jump into than more complex competitors.
• Authentic Test Feel 📝 - It genuinely feels like taking a proctored IQ test, just on your phone. The question styles and timing (when used) create a more authentic pressure compared to casual puzzle games.
• Great for Quick Sessions ⏱️ - You can do a full test or just a few puzzles in a short break. Its pick-up-and-play nature makes it more accessible for daily practice than some subscription-based rivals.

• Limited Long-Term Hook 🔄 - Once you've done the available tests, the replay value can dip compared to games like 'Brain Test' which have endless, quirky levels. The core appeal is re-taking tests to improve your score.
• Niche Appeal 🎯 - If you're not specifically interested in IQ-style puzzles, the app might feel repetitive. It lacks the variety of mini-games found in other installs from the puzzle genre.
• Basic Presentation 🖥️ - The visuals are functional but very basic. Don't expect the polished animations or thematic environments of premium puzzle games; it's all about the mental challenge here.
