IQ – quiz for iOS downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.
Active users
All platforms, worldwide. Free with an account.
Stickiness (DAU / MAU)
how many monthly users open it on a given day
How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

About IQ – quiz for iOS
Multithreading, memory, architecture. New AI mode based on Foundation Models, hardcore challenges, and global rankings.
Are you preparing for a Middle/Senior interview or just want to keep your brain in shape?
I've collected and packaged everything that's asked in technical interviews into one app and added a powerful task generation engine.
What's inside?
Fundamentals: hardcore questions on topics to think about.
Multithreading: GCD, Operations, Actors, data races.
Memory management: ARC subtleties, retain cycles, and much more.
Algorithms: From Big O to trees and graphs.
Architectures: Breaking down MVC, MVVM, VIPER, TCA.
Compiler and runtime: How Swift works under the hood.
Infinite task generator
The main feature of the update is Dynamic Mode. The app generates unique cases and questions in real time. This allows you to not only memorize the correct answer, but also to truly understand how a particular technology works by encountering new formulations each time.
Training modes
Time sprint: Live coding stress simulation. Learn to think fast.
One mistake: “First mistake” mode. For those who are confident they know the documentation by heart.
Progress and Rating
Detailed statistics will show your weak areas (for example, if you are good at UI but struggle with algorithms).
And the global leaderboard will help you compare your grade with other developers in the community.
Adjust the difficulty to suit yourself, choose topics, and download skills.
