Best Apps for IB Students in 2026: Tested and Ranked

Six subjects. Internal assessments in every one of them. A Theory of Knowledge essay, a 4,000-word Extended Essay, CAS hours, and two full exam sessions two years apart. The IB is a different kind of workload, and the apps that serve GCSE or A-level students well don't always transfer cleanly to what the IB demands.

This guide covers seven apps IB students genuinely use, ranked by how much active learning they drive and how well they fit the IB's specific pressures. Each entry says what the app is best for, because the right stack for you depends on how you work.

The best apps for IB students in 2026 are Root (adaptive AI tutor and study manager), Anki (spaced-repetition flashcards), Revision Village (IB Maths past papers by topic), Quizlet (vocabulary and key terms), GoodNotes (iPad note-taking and PDF annotation), Forest (focused study sessions), and Todoist (deadline and task management).

Why the IB needs specific apps

The IB's marking schemes work differently from most national qualifications. Rather than right-or-wrong answers, they use command terms (define, describe, explain, evaluate, discuss) and markbands that reward specific depths of response. That matters for which apps are actually useful: a multiple-choice quiz that checks whether you selected the right option trains you for a type of question that barely exists in IB exams. You need tools that let you write, argue, and receive feedback on the quality of your thinking.

The evidence on what actually works supports this. Dunlosky et al. (2013) published a large review of study techniques in Psychological Science in the Public Interest, rating each by its effect on long-term learning. Practice testing and distributed practice (spacing reviews over time rather than cramming) received the highest utility ratings. Re-reading and highlighting received low utility ratings, despite being the default habit for most students. The apps that work best on this list build in one or both of those high-utility techniques.

1. Root: Best for tutoring and revision in one place

Root (roottutor.com) is an AI tutor and study manager built for the IB by an IB student, around the IB's specific demands, and it also supports GCSE, IGCSE and A-level students. It is free to use, no card needed.

What separates Root from the other apps on this list is what it actually does with a subject. In tutor mode, Root does not hand over the answer: it asks questions, challenges your reasoning, and guides you toward understanding, the way a good teacher would. For IB subjects where extended written analysis carries the marks, that Socratic approach builds the kind of independent thinking that "evaluate" and "discuss" questions reward. In exam practice mode, Root marks your written answers against IB-style criteria, shows exactly where you dropped marks, and explains what a higher-band response would have included. Getting that kind of written feedback without a private tutor is genuinely rare.

Root's revision mode runs a short check-up on your past units and sorts each topic into remembered, shaky or learn next, and spaced review (which you switch on per unit) brings topics back on a set schedule. The more sessions you do, the more tailored it becomes: it remembers what you consistently get wrong and concentrates there, which is where revision time pays off most.

The deeper difference from other apps is that Root is a connected system rather than a stand-alone tool. Every session is saved as a unit with a summary, your notes and the full conversation, so the chemistry session you had on organic mechanisms in September is still there, resumable and revisable, when April's exams arrive. Revision mode can revise your own past units, not just generic material. Test Prep runs a real timed mock, marks it in depth, and you can take that marked feedback straight into a tutor session to work on the gaps immediately. And for the IB's central challenge, the sheer volume of the workload, Root's Planner schedules your homework, keep-up, revision and test run-up sessions around your actual week and replans when your week changes.

Managing six subjects alongside IAs, an Extended Essay and TOK is where most IB students lose hours to low-priority tasks while genuinely urgent revision slips. Root handles that system for you: you don't need to figure out what to study next, it tells you. That is what most students would otherwise need several separate apps and a tutor's marking time to replicate.

Root is free to use, no card needed, and new accounts get a 7-day free trial of everything. For a full breakdown of what each mode does, see what Root does. To try it, set up a free account in a couple of minutes.

We built Root for exactly this: active teaching, examiner-style marking, weak-topic check-ups and a plan for every study session, in one place.

2. Anki: spaced-repetition flashcards

Anki (ankiweb.net) is the most established spaced-repetition flashcard app available. It is free on desktop and Android; the iOS app (AnkiMobile) is a paid one-off purchase. A large library of shared IB decks covers Biology, Chemistry, History, Economics, Psychology and Language B vocabulary, and you can build your own directly from your class notes.

The algorithm behind Anki draws on decades of research into the spacing effect, first documented systematically by Hermann Ebbinghaus in his 1885 work Über das Gedächtnis and validated extensively since. Each card is scheduled to reappear just before the point where you would typically forget it, which means difficult material comes back often and well-learned material comes back rarely. Over weeks of consistent use, this produces significantly better long-term retention than reviewing a fixed stack on a fixed schedule.

For IB Biology, Chemistry, Psychology and History, where there is a genuine volume of content to recall accurately under exam conditions, Anki is one of the most efficient tools available. The shared community decks for IB Biology HL and SL are particularly comprehensive. For more on how the underlying method works, see spaced repetition and how to use flashcards.

Honest limitation: Anki is a memorisation tool, not a writing or reasoning tool. It will not help you practise a structured evaluate argument or work through an IB Maths problem. Use it alongside something that drills active written responses.

3. Revision Village: IB Maths on any device

Revision Village (revisionvillage.com) is the most focused IB Maths resource available, covering Mathematics: Analysis and Approaches (AA) and Applications and Interpretation (AI) at Standard and Higher Level. Past-paper questions are organised by topic with video worked solutions for each. You can access it on a browser on any device, and they have iOS and Android apps.

The topic-bank format is what makes it genuinely useful for targeted revision. Rather than sitting a full past paper in one go, you can drill every IB Maths question from recent exam sessions on a single topic: integration by parts, complex numbers, or probability distributions. That is a much faster way to close a specific weakness than jumping between unrelated problems.

Revision Village is primarily a paid subscription, though a portion of content is free. Students taking Maths AA HL or who have specific topic gaps they need to close before exams generally find it worth the cost.

Honest limitation: Revision Village covers IB Maths only. Students who want revision support in Sciences, Humanities or Language subjects need different resources for those subjects.

4. Quizlet: quick vocabulary and key terms

Quizlet (quizlet.com) has a large IB community that has produced flashcard sets for most subjects, including Language B vocabulary, Biology key terms, History case studies and Economics concepts. The app works on iOS and Android; the core flashcard and Learn modes are available on the free tier.

It is accessible and quick to start with, which makes it practical for the vocabulary-heavy parts of the IB. Quizlet's Learn mode and Match game add some active retrieval to the basic flashcard format, which is more effective than simple reading.

Honest limitation: Quizlet's algorithm is less sophisticated than Anki's spaced repetition, and several of its more useful features now sit behind the Plus subscription. For pure flashcard efficiency over a long revision period, Anki is the stronger tool. Quizlet works well for quick, low-friction term practice rather than as a primary long-term revision system.

5. GoodNotes: handwritten notes for iPad

GoodNotes (goodnotes.com) is the note-taking and PDF annotation app most widely used among IB students who work on an iPad. You can import IB past papers or textbook pages as PDFs, annotate them with an Apple Pencil, and keep class notes organised by subject and date.

The ability to annotate past papers by hand is genuinely useful for Maths and Sciences, where typed notes don't capture diagrams, graphs and working cleanly. Many IB students also use GoodNotes to keep IA notes, EE drafts and TOK reflections organised in one place rather than across multiple paper notebooks.

GoodNotes is iOS, iPadOS and macOS. It has moved to a subscription model with GoodNotes 6. Notability is a strong alternative with similar features on Apple platforms. For Windows, Android or Chromebook users, Microsoft OneNote is the most capable free option.

Honest limitation: GoodNotes is for note-taking and organisation. It does not test you, track your weaknesses or give you feedback on your understanding. It is most useful as a companion to tools that do.

6. Forest: staying off your phone during sessions

Forest (forestapp.cc) is a focus app built around a simple mechanic: you plant a virtual tree at the start of a study session, and the tree dies if you leave the app before the timer ends. Over time you grow a virtual forest. The app also partners with a real tree-planting organisation, so completed sessions contribute to trees planted in the real world.

The mechanics are simple, and that is partly why they work. For IB students who find themselves reaching for their phone between paragraphs, the visible and mild commitment of watching a tree grow is a genuine friction point that reduces interruptions. Forest supports Pomodoro-style session lengths and shows your focus time over days and weeks.

It is available on iOS and Android; a basic version is free, and the paid version adds features and more real-tree planting.

Honest limitation: Forest is a focus aid, not a revision tool. It does nothing to improve what you do during a session; it only helps you stay off your phone while you do it. The quality of revision matters far more than its duration.

7. Todoist: IB deadlines and tasks in one place

Todoist (todoist.com) is a task management app that runs on iOS, Android, desktop and web. For IB students managing IA submission dates, EE milestones, CAS documentation deadlines and homework assignments across six subjects at the same time, one reliable place where every task lives with due dates and subject labels significantly reduces the mental overhead of deciding what to do.

The free tier covers what most students need: task creation, due dates, project folders by subject, and priority levels. The Pro tier adds reminders and more advanced filtering.

Honest limitation: Todoist tracks tasks; it does not generate a study plan or adapt to how your week changes. Root's Planner mode goes further, actively scheduling and rescheduling your study sessions around your real week. Todoist is strongest as a capture tool for IB deadlines and homework rather than a full study system.

Which apps should you actually use?

More apps is not better. Two or three that you use consistently will outperform seven you open once and abandon.

A practical baseline for most IB students:

• Daily active practice and written-answer feedback: Root (free to use)
• Content-heavy subjects (Biology, Chemistry, History, Psychology): Anki for terms and definitions you need to recall accurately
• IB Maths: Revision Village if you have specific topic weaknesses to close
• Notes and past-paper annotation (iPad): GoodNotes or Notability
• Staying off your phone during sessions: Forest if you need it

The central question is what sits at the core of your daily IB revision. If it is something that tests you and marks your written responses, your preparation is heading in the right direction. If it is something that lets you re-read notes or watch videos, you are staying comfortable but not building retrieval strength. Dunlosky et al. (2013) found practice testing to be among the highest-utility study techniques available, and that matters for how you choose your apps.
