About Monster Math: Games For Kids

I saw this app with a crazy high rating in the App Store and figured I’d try it for my 8-year-old. We’ve had it on my iPhone 15 Pro for a little over a month now. My first impression was honestly mixed. The app itself is bright and the monsters are cute, but I was immediately hit with prompts to start a free trial for the “full experience.” It felt a bit pushy for a kids’ app. I decided to ignore that and just explore the free stuff first. After a few sessions, I started to see the appeal. My daughter, who usually groans at extra math practice, actually asked on a Tuesday after school if she could “play with the monsters.” That was a win I wasn’t expecting.

Core Features

The free version gives you a decent chunk of games focused on basic addition, subtraction, and multiplication. My kid loves the one where you feed a monster the correct answer. The characters do little dances and the sounds are fun without being annoying. I like that you can set a specific grade level or learning path. I set it to second grade skills, and it started throwing two-digit problems at her pretty quickly. The progress tracking is simple but useful. It shows you which types of problems they’re getting right and which ones need work. I didn’t see any flashy leaderboards comparing her to other kids, which I actually appreciated. It felt focused on her own improvement.

Real-World Use

This became our go-to for waiting room time or short car rides. Last week, we were stuck at the dentist’s office for 20 minutes, and instead of getting fidgety, she quietly worked through a bunch of subtraction problems to earn a new hat for her monster avatar. She doesn’t see it as homework, she sees it as a game where the currency happens to be math answers. I’ve noticed her mental math speed has picked up a bit. She blurted out the total for our two ice creams at the park last Saturday before I could even pull out my phone. That felt like a real, tangible result from all those monster-feeding sessions.

Pricing & Value

Here’s the big sticking point for me. The free content is good, but it feels designed to make you want the subscription. After a few days, my kid kept seeing locked worlds and special monsters she couldn’t access. The pop-ups for the subscription trial are frequent. I eventually caved and looked at the price. It’s not the most expensive kids app out there, but the constant nudging left a bad taste. Once you pay, you do get a lot more—new game modes, detailed reports, and all the characters. The value is there if your kid is truly hooked, but I wish the free tier felt a bit more complete so the upgrade felt like a bonus, not a necessity.

Updates & Support

The app has updated once since I got it, fixing some minor bugs. I had one issue where the sound effects cut out randomly. I emailed support from the link in the app settings. I didn’t hear back for three days, which was longer than I hoped. But when they did reply, it was actually helpful. The person asked what iOS version I was on and suggested a specific phone restart sequence, not just a generic “reinstall the app” response. It worked. So, they were slow but knowledgeable, which is better than fast and useless.

Data & Privacy

This is where I always get nervous. I went digging through their privacy policy before letting my daughter play. They do collect some data for analytics—like how many problems are attempted—which is pretty standard for improving the app. I was relieved to see they state they don’t sell personal data to third parties for advertising. The app doesn’t ask for weird permissions like contacts or location, which is a huge green flag for me. All the progress is stored locally on the device or linked to a parent account you can make. I made a bare-bones account with just an email. Overall, for a free app, it felt more respectful of privacy than most. I didn’t get the creepy feeling that my kid was the product.

Frequently asked questions
What math skills does Monster Math cover in the free version?

The free version includes games focused on basic addition, subtraction, and multiplication. You can set a specific grade level, like second grade, and the app will adjust problems accordingly, including two-digit questions.

Can I track my child's progress in Monster Math?

Yes, the app has simple but useful progress tracking that shows which types of problems your child is getting right and which ones need more practice. It focuses on individual improvement rather than comparing your child to others.

The app keeps asking me to start a free trial. Can I still use it without paying?

Yes, you can ignore the trial prompts and use the free content. The free version offers a decent amount of games and learning paths, though the full experience requires a subscription.

My child gets bored with regular math practice. Will Monster Math keep them engaged?

Many kids find it engaging because it feels like a game where math answers are the currency. Earning rewards like new hats for monster avatars and seeing fun character animations can motivate children to practice without realizing it's homework.

How does Monster Math compare to other math apps like Khan Academy Kids?

Monster Math is more game-driven with cute monsters and immediate rewards, which can be more motivating for some kids. Khan Academy Kids offers a broader curriculum and is completely free, but Monster Math's focused math practice and progress tracking may feel less overwhelming for children who need targeted skill building.
