Best Study Apps (2026): Anki, Quizlet, Goodnotes, Forest

The best study app depends on what you're studying and how. Anki is the best app for memorizing information long-term — its spaced repetition algorithm is scientifically the most effective memorization method available. For quick studying before a test, Quizlet is more approachable.

1. Anki — Best Spaced Repetition (9.2/10)

Anki implements spaced repetition — a learning method backed by decades of cognitive science research. Cards you find easy are shown less frequently; cards you struggle with are shown more. Over time, Anki schedules reviews at the optimal moment just before you would forget, maximizing long-term retention efficiency.

The interface is utilitarian. The community deck library has pre-made flashcard sets for almost any subject (medical school boards, language vocabulary, history). Anki is free on Android and desktop; the iOS app is $24.99 (a one-time purchase that funds ongoing development). If you're studying for anything requiring long-term retention — medical exams, bar exam, language vocabulary, standardized tests — Anki is the right tool.

2. Quizlet — Best for Quick Studying (9.0/10)

Quizlet is the most accessible flashcard and study tool. Creating a study set is fast. The multiple study modes (Learn, Flashcard, Test, Match, Gravity) hit different memory pathways. The massive library of user-created sets means you can often find a pre-made set for any topic. The AI features (auto-generating study sets from notes, practice tests from a document) save significant setup time.

3. Goodnotes — Best iPad Note-Taking (8.9/10)

Goodnotes is the best handwriting-based note-taking app for students with iPads and Apple Pencils. Handwriting recognition converts notes to searchable text automatically. Templates (lined paper, graph paper, music staves) cover every note-taking scenario. The notebook metaphor with tabs and pages feels natural. For visual learners who process information better through handwriting than typing, Goodnotes provides a genuinely superior study experience.

4. Forest — Best Focus App (8.7/10)

Forest gamifies focus: plant a virtual tree, which grows while you stay in the app. Leave to check social media, and the tree dies. Accumulated focus time builds a virtual forest, and the developers donate to plant real trees through partner organizations. The gamification is simple but surprisingly effective. For students who struggle with phone distraction, Forest provides gentle accountability.

5. Notion — Best Study Workspace (8.8/10)

Notion's flexibility makes it excellent for organized studying: course wikis, reading lists, project tracking, and linked notes for cross-subject research. Students who invest in building a Notion workspace for their courses often report better recall simply because organizing information forces engagement with it. Templates for study planning are available for free in the community.
