Best Study Apps (November 2026): Free and Paid, Ranked

How we picked the best study apps

We’ve organized apps by purpose, because no one app does everything a student might want. Different apps are better for different use cases, so we’ve split our top picks into categories, based on their primary use case (creating/reviewing flashcards, taking notes, learning from your own course materials and improving focus/distraction management). We also paid special attention to what features are offered for free (compared to paid plans/pricing), supported platforms and evidence-based study techniques.

According to an Association for Psychological Science review summarizing research on ten different learning techniques, some techniques such as practice testing and distributed practice (spacing your learning sessions out over time) were found to be high utility strategies for learning, while other techniques like rereading or underlining were found to be low utility techniques. In a classic test-enhanced learning experiment, for example, students who took recall tests remembered significantly more of the material a week later than did students who simply reread the same material. Apps that encourage evidence-based learning techniques (like actively testing your knowledge on a spaced schedule) were given preference over apps that focus more on other activities (like passively storing information).

Quick note: we didn’t run a hands-on test of the study apps below, paid or otherwise. All features/pricing are subject to change, so always recheck current details/pricing with the vendor before making any purchases. (We should also mention that we make StudySim, so take its review accordingly.)

Best study apps compared

TL;DR, in most cases you’re likely to find that one notes app, one flashcard app and one app for managing your focus/distractions will likely suit your needs just fine (rather than five apps that all somewhat overlap with each other).

1. Anki: best free study app for flashcards

Anki is a powerful flashcard app that leverages a highly-effective (research-backed) spaced repetition system (SRS) to help you commit information to memory (by resurfacing information at just the right time, when you’re on the verge of forgetting it, also known as distributed practice). While Anki’s interface leaves a bit to be desired aesthetically, it more than makes up for this with powerful flashcard review and authoring features (plus you can download pre-created flashcard “decks” made by other users). Anki is free on AnkiDroid (Android), as well as on Windows/Mac/Linux (with syncing provided for free via Anki’s AnkiWeb offering). The iOS app, AnkiMobile is a one-time $24.99 purchase, to support development efforts.

The trade-off is setup. Anki looks plain, and you will either make your own cards or import shared decks. If you’re new to card writing, our how to make flashcards guide should help you understand some of the rules a deck needs to follow to be worth a look.

2. Quizlet: best for ready-made study sets

Quizlet is a popular flashcard app for High-School/University students, with a repository of pre-built flashcard decks (created by other students). Quizlet offers a free plan (including access to activities, diagrams, flashcards and practice questions) as well as a paid Quizlet Plus plan (offering extra features, like Practice Tests, Test, Study Guides, Expert Solutions and Learn), available as an in-app purchase ($44.99/$9.99) via the App Store. Bear in mind that pre-created Quizlet flashcard decks can vary in quality (as they were made by your fellow students), so we always recommend comparing them with your own lecture/class notes, just to be safe.

Premade sets save time, but check them against your own notes, since anyone can publish one. If the paid version is the issue, then check out our list of Quizlet alternatives to see what’s free.

3. Knowt: best free all-in-one study app

Knowt is an app that combines file creation and collaboration. Its (generous) free (Basic) plan includes unlimited storage (collaboration/files), as well as access to its content library (containing ~5 million study resources). Its paid (Ultra) plan ($95.99 billed upfront (annually) for $7.99 per month or $24.99 per month (month-to-month)), unlocks ad-free usage, AI-powered summarization of slides/images/videos/PDFs, access to ACT/SAT/AP test prep content, a lecture recording summarizer and its AI-powered voice tutor.

4. Gemini Notebook (formerly NotebookLM): best for studying from your own sources

Google’s NotebookLM (recently renamed Gemini Notebook in July 2026, though it’s essentially the same app, with your existing notebooks still intact) lets you upload your own lecture/class notes (up to 50 sources per notebook on the standard plan; Google AI Plus doubles the usage limits and raises the cap to 100 sources), and pose questions about its contents, receiving sourced/cited responses. You can also transform your uploaded sources into mind maps, Audio Overviews, flashcards and quizzes, making it a strong study assistant for long readings.

5. StudySim: best for practice quizzes from your notes (we make it)

StudySim is our own app, so weigh this entry accordingly. StudySim is an AI-powered learning app, helping you learn from your own lecture/class notes, slides or PDFs (by automatically generating practice questions, flashcards and even podcasts, among other things). The free PDF to flashcards generator is able to take in a PDF or your notes and will create eight question-and-answer cards. The free AI quiz generator can be used to generate a five-question practice quiz (with answers and explanations included). You can try it out for free (without an account, you get 2 free generations, with an account you get 8 generations per month).

StudySim Pro ($1 for the first 3 days, then $120 per year (billed annually) or $20 per month (month-to-month), unless you cancel)), lets you combine up to 15 sources into a “course”, and generates comprehensive study guides, flashcards, podcasts (with 2 distinct AI voices), as well as written and multiple-choice quizzes/exams. StudySim is not a handwriting app or a focus timer, and the free tools have tight usage limits, so most students pair it with a notes app. Or you can check out the study guide generator or browse free practice tests.

6. Notion: best for organizing your classes

Notion is an all-in-one workspace that you can use to take notes and build dashboards for each of your courses (staying on top of assignments/deadlines and organizing your notes, within a single app). It offers a generous Free plan (note: file uploads are limited to 5 MB (each), on the Free plan), as well as a (free) Education Plan (for one workspace per eligible student, verified with a school email) and a paid Plus plan ($10 per seat per month).

7. Goodnotes: best for handwritten notes

Goodnotes is a note taking app that excels at digitizing handwriting (even letting you handwrite directly on top of PDFs, perfect for annotating lecture slides/materials). It’s available on iPadOS/iOS, Android, Windows, Mac and via the web. Its free plan is somewhat limited (up to 3 notes/files, in total), but its paid Essential ($11.99 per year, for unlimited audio recording and files) and Pro plans ($35.99 per year, adding cross-platform syncing of your entire library and collaboration), offer 7-day free trials.

8. Microsoft OneNote: best free note-taking app

OneNote is Microsoft’s free note taking app, offering a familiar interface (if you’re already using Microsoft 365 at school), for taking handwritten/typed notes (with highlighting/diagrams/digital ink support) that is available on Windows PCs, iPads/other tablets, Macs and mobile phones.

9. RemNote: best for notes and flashcards in one place

RemNote is a unique app, combining notes and flashcards (with spaced repetition, for scheduling reviews) into a single solution, even including an exam scheduler. Its Free plan is quite generous (offering unlimited notes and flashcards, as well as 3 PDFs with annotations), with more expansive paid Pro ($96 per year (billed annually) for $8 per month) and Pro with AI ($216 per year (billed annually) for $18 per month), plans available. It’s available as mobile (Android/iOS) and desktop apps.

10. Forest: best study app for focus

Forest is a cute pomodoro technique-inspired app that grows a tree while you’re focused (which withers/dies if you leave the app to use others). It’s free to download (with in-app purchases/subscriptions, offering monthly and annual subscription options), and claims to use proceeds to plant actual trees (with the non-profit Trees for the Future).

Best study apps for college students and best free study apps

College typically entails more courses (per student) and often lengthier/more complex reading, making source-based learning apps particularly worthwhile. A simple college setup is Notion or OneNote for notes and deadlines, Anki or Knowt for flashcards, and Gemini Notebook or StudySim to turn readings into questions. If you’re after a completely free solution, consider using Anki (on the desktop), OneNote, Knowt’s (generous) Basic (free) plan, and the free offering from apps like Forest.

How to pick the right study app

Whichever apps you opt for, we recommend starting with the one addressing your most pressing learning need (instead of simply picking the most feature-packed one), giving each app you add some time (at least a couple of weeks) to assess its effectiveness for you, and (perhaps counterintuitively) using them to quiz yourself (instead of simply re-reading your notes).

Whatever you pick, use it to quiz yourself rather than to reread. Decide which app to use for each task (our how to study effectively guide will help you plan sessions).
