Alright, let's talk about the IQ Test app by Aliaksandr Uvarau. You can find this one on Google Play and it's a pure mobile game, no PC or console versions on Steam or Xbox or Switch. It first launched a few years back and has been sitting pretty with over 10 million installs on Android, which is a solid number for a brain teaser app. The best part? It's completely free to download and play. There are in-app purchases, but they're mostly for removing ads or unlocking hints, usually costing around $1 to $3 each. So, if you're okay with a few interruptions, you can enjoy the whole experience without spending a dime. I downloaded it on my Android just to kill time during commutes, and honestly, it's been a nice little mental workout.

Playing this IQ test is pretty straightforward: you get a series of logic puzzles, pattern recognition tasks, and spatial reasoning challenges. The game throws a timer on each question, so you're forced to think fast. The best part for me is how it tracks your progress and gives you a final IQ score at the end. It's not a clinical test by any means, but it feels rewarding to see your number improve over time. My favorite part is the variety—one minute you're solving a matrix puzzle, the next you're figuring out which shape fits where. It keeps the brain engaged without feeling like a chore. After installing it, I found myself coming back daily just to beat my previous score.

Compared to other brain training apps like “Brain Test: Tricky Puzzles” or “Mensa IQ Test,” this one stands out for its no-nonsense approach. Brain Test is more about silly, out-of-the-box tricks, which is fun but not serious. Mensa's app is good but often feels too rigid. The Aliaksandr Uvarau version hits a sweet spot—it's challenging enough to feel legit but accessible for casual play. I'd recommend it because it's lean and focused. No endless tutorials or flashy animations, just pure puzzles. If you're on Google Play looking for a quick mental challenge without a big time commitment, this is your app. Plus, the low cost for removing ads means you can get an uninterrupted experience for pocket change.

• 🕹️ Quick Play Sessions – Each test takes about 10-15 minutes, perfect for short breaks. Unlike “Lumosity” which demands daily logins for long-term progress, this app lets you jump in, solve a set of 40 questions, and get your score instantly.
• 📊 Detailed Score Breakdown – The app doesn't just give you a number; it shows how you performed in areas like logic, math, and spatial awareness. That's way more useful than the vague “brain age” you get from “Brain Age” on Nintendo Switch.
• 🧩 Diverse Puzzle Types – You'll get verbal analogies, numeric sequences, and visual patterns all in one test. Most similar apps, like “IQ Test - Brain Training,” stick to one style per session, which gets boring fast.

• 💰 Completely Free Core Experience – You can play the full test without paying a penny. Compare that to “Mensa IQ Test” on Android, which locks half the questions behind a paywall or subscription. Here, in-app purchases only remove ads or give extra hints, so you're never forced to spend.
• ⚡ Fast Feedback Loop – After each question, you see if you got it right immediately. This instant feedback keeps you learning on the spot, unlike “Elevate,” which waits until the end of a session to show results. It makes the whole process more engaging and educational.
• 📱 Lightweight App Size – The download is under 10MB on Google Play, so it installs quickly even on older Android devices. In contrast, “Peak” takes up over 50MB and often lags on budget phones. This IQ Test runs smooth no matter what you're using.

• 🔇 Repetitive Ad Breaks – The free version shows ads after every few questions, which can break your concentration. Apps like “Brain Test: Tricky Puzzles” also have ads but let you skip them more frequently without downloading anything extra. Here, you'll eventually want to pay $2 to remove them.
• 📏 Limited Question Pool – After two or three full tests, you start seeing repeated puzzles. “Mensa IQ Test” on iOS has a much larger bank of unique questions, so you can keep retesting without memorizing answers. This app's replay value takes a hit because of that.
• 🔢 No Timed Practice Mode – You can only do the full 40-question test with the timer on. Similar games like “Brain Age” on Switch offer a practice mode without pressure. If you want to improve your logic speed without stress, there's no option here to work on specific skills outside the main test.
