Picking the wrong quiz app costs more time than it saves. The right one turns your existing content into a polished assessment in seconds, tracks how students actually perform, and runs on every device without a complicated setup.
This guide covers the best quiz apps available on Android and iPhone right now, what each one does well, where they fall short, and which one gives educators the clearest advantage.

What to Look for in a Quiz App
Four factors separate a useful tool from a frustrating one:
Content import: Can it generate questions from materials you already have, or do you write every question by hand?
Question variety: Multiple-choice, true/false, and short-answer formats at minimum keep assessments flexible.
Cross-device access: Good options work on Android, iPhone, tablets, and browsers without locking students into one platform.
Reporting: Class averages tell you little. Strong reporting shows which questions tripped students up and tracks improvement over time.
Best Quiz Apps for Android & iPhone
QuizWiz by OneScreen: Best Overall for Educators
QuizWiz is the most capable quiz app for educators and trainers available today. Built by OneScreen and free to start, it uses AI to generate complete, editable quizzes from your own content in under 30 seconds. It runs on any Android device, iPhone, browser, or OneScreen touchscreen display.
The workflow is fast. Upload a PDF, paste a URL, drop in a DOCX or TXT file, or paste content directly. Set the difficulty level, question count, and format. QuizWiz builds the quiz and saves it automatically to a searchable library so nothing gets buried or lost.
Delivery options include Google Classroom, Google Forms export, PDF, TXT, and email. No extra configuration for any of them.
QuizWiz Pro extends the input limit to 30,000 words, adds auto-completion for content under 50 words, unlocks direct Google Forms integration, insight reports, and daily performance email summaries. The free plan covers regular classroom use with no cap on how many quizzes you create.
As Tony B., a teacher and digital learning coach, put it:
“I can choose the content I want the questions focused on, copy and paste it in QuizWiz, and quickly get a great quality quiz to use in Google Classroom.“
QuizWiz also connects to three other OneScreen apps: Scrybe (real-time transcription in 28 languages), Lessn (standards-based lesson planning with 10,000-plus pre-built lessons), and SuprNotes (automated session summaries that combine audio, annotations, and shared files). Together, they cover the full teaching cycle from prep through review.
Kahoot!: Best for Live Group Competition
Kahoot! runs well in a shared-screen classroom setting. Students join on their phones, a timer counts down, and the competitive format pushes participation fast. It’s effective for review sessions where energy and pace matter.
Available free on Android and iPhone, with paid tiers for advanced analytics. Every question is written manually. There’s no content import, so prep time doesn’t decrease with volume.
Quizlet: Best for Student Self-Study
Quizlet works well for student-paced study on vocabulary, definitions, and recall-heavy subjects. Students build flashcard sets and test themselves using matching, written, and multiple-choice formats. A large library of pre-made study sets helps when time is short.
The free version covers the basics. Quizlet Plus adds AI assistance and offline access. Teachers can assign sets to classes, but generating assessments automatically from uploaded lesson content isn’t part of the standard workflow.
Quizizz: Best for Self-Paced Classroom Games
Quizizz sits between Kahoot! and Quizlet in pacing. Students answer at their own speed while the teacher monitors live progress from a dashboard. The Android and iPhone apps are polished, and students tend to find them easy to start using.
AI question generation from your own content sits behind a premium subscription. Standard question creation is still manual entry.
Google Forms: Best Free Option for Simple Assessments
Google Forms isn’t a dedicated quiz app, but it handles straightforward assessments at no cost with no volume limits. Questions are entered manually, grading is automatic, and results push directly to Google Sheets. It integrates cleanly with Google Classroom.
The limitation is intelligence. It doesn’t generate questions from your materials, doesn’t surface learning patterns, and requires consistent manual effort to build and maintain over time.
Mentimeter: Best for Workshop Presentations
Mentimeter started as a polling tool and added quiz functionality suited to presentations, workshops, and training sessions. Questions embed directly into slide decks and participants respond live without downloading anything.
Deeper analytics require a paid plan. It fits well for single-session engagement moments but isn’t built for high-volume assessment creation or ongoing classroom use.
Why QuizWiz Runs Ahead of the Field
Most tools in this category are delivery systems. The educator writes every question; the platform runs the session. Logistics are handled, but the workload of creation stays entirely with the teacher.
QuizWiz inverts that. You bring the content. The AI writes the questions.
At 30 seconds per quiz versus 30 minutes, that difference compounds quickly across a semester. The searchable library keeps everything organized without extra effort from the educator. Output formats match where teachers already work. No other quiz app in this category combines AI generation from your own content, cross-platform delivery, Google Classroom export, and a fully capable free tier in one package.
OneScreen GURU: Live Support When It Counts
OneScreen includes GURU with every product, QuizWiz included. GURU is live human support, available 24/5. Not a chatbot. Not a help article queue. A trained agent joins your screen within minutes, sees what’s happening in real time, and works through the fix with you directly.
For educators running live assessments mid-lesson, that response time matters. A technical issue at 9:15 on a Tuesday needs a resolution in minutes, not a ticket waiting overnight.
