Knowunity is a study app for high school students preparing for the SAT, ACT or AP exams. Its centerpiece is a day-by-day exam plan built around your test date and topics, with flashcards, quizzes, summaries, mock exams and voice practice feeding into it. Homework help is part of the mix too.
A German study platform with an exam-plan approach
Knowunity is published by Knowunity, whose website is knowunity.de. The app first appeared on September 9, 2020, and the package ID is de.knowunity.app. The latest version is 6.45.1, updated on November 4, 2026.
The app offers a study assistant called Knowie. The developer says 30 million students already study with it, and the core tools are free.
Exam plan, voice recall and photo homework help
Everything is organized around an exam plan. You enter your test date and topics, and the app builds a day-by-day schedule with matching notes and flashcards. A class timetable can be added so study sessions fit around lessons, and the plan adapts as the test gets closer.
Practice leans on active recall. Quizzes and flashcards ask you to remember answers, and mastery tracking shows each topic moving from shaky to solid. Voice recall lets you say an answer aloud for the app to check, and a voice mode in chat works like a spoken tutor.
For homework, you photograph a problem in math, chemistry, physics or biology and get a step-by-step walkthrough. Each class can have its own chat. You can also upload PDFs, slides, photos, handwritten notes, text, links, old flashcard decks or a YouTube video, and the app turns them into flashcards, quizzes and summaries.
Full AI-scored mock exams follow real SAT and AP formats, and results feed back into the plan. The library holds over 1 million notes, summaries and past-paper solutions shared by students. Streaks, XP and weekly leagues of up to 30 classmates, from Bronze to Gold, add a competitive layer.

Knowunity runs on Android 8.0 or newer and carries an Everyone 10+ content rating. Eight screenshots show the study screens. The core tools cost nothing, though ads appear and in-app purchases are offered for extras. No download size is listed.
