Playable for everyone
Quiz King has been built with VoiceOver from the start and is developed together with blind testers.
Playable with VoiceOver
Developed together with blind testers. Focus moves to each new question, and time and score are always within reach.
Answer out loud
Say the answer or its letter – or just “true” or “false”. Speech recognition runs only on your iPhone.
Quizmaster voice
Without VoiceOver, the Quizmaster can read questions aloud, in English and German, wherever a recording already exists.
Large text
Text grows with your iPhone's text size, up to the largest settings.
Reduce Motion
Animations switch off when Reduce Motion is on or VoiceOver is running.
Listen: the Quizmaster

Transcript: “Let's go!” – “What is the capital of Australia?” – “You won!”
Frequently asked questions
Does Quiz King cost anything?
No. Quiz King is free and shows no ads. Play Arcade, True or False and Lightning Round as often as you like.
Every day, 5 random duels and one marathon run are free. Beyond that you need tickets – you earn them by playing and through achievements, or you can buy them.
There is an optional subscription, Quiz King Plus: unlimited random duels, 50 tickets every month and Mistake Training. Plus gives no edge in scoring, rating or the marathon.
Which devices does Quiz King run on?
iPhone and iPad with iOS 17 or later.
Do I need an account?
You don't have to sign up. On first launch the app creates an account and quietly backs it up in your private iCloud, so it comes back on a new device with the same Apple Account. Without iCloud it stays on this device only.
You can delete your account in the app at any time.
What happens to my data?
Quiz King has no ads and no tracking. Speech recognition runs only on your iPhone; nothing leaves the device. The game server keeps no access logs with IP addresses.
