Best study app: the short answer
There is no single best study app — there are four jobs, and a different app leads each one. For ready-made flashcards, Quizlet wins. For tunable spaced repetition, Anki. For free video courses, Khan Academy. For solving a maths problem step by step, Photomath. For daily exam practice generated from your own notes and graded like the real paper, Skoolskill.
Pick by job, not by app-store rating. Below is each category, what it’s genuinely best at, and where you might want two apps instead of one.
The four study-app categories
- Flashcard apps (Quizlet, Anki) — recall of facts, terms, vocabulary.
- Problem-solvers (Photomath) — seeing the worked method for one maths problem.
- Course/video libraries (Khan Academy) — learning a topic from scratch, structured and free.
- Practice generators (Skoolskill) — turning your own material into daily, graded, exam-style questions.
Most students need one app from category 1 or 3 to learn material, plus a category-4 app to actually practise it under exam conditions.
How the categories compare
| Category | Lead app | Best at | Own material? | Free tier |
|---|---|---|---|---|
| Flashcards | Quizlet | Huge shared library, study games | Partial (build sets) | Yes (ads) |
| Spaced repetition | Anki | Customisable, proven algorithm | Yes (build decks) | Yes (desktop/Android) |
| Video courses | Khan Academy | Free structured lessons | No | Yes (all free) |
| Maths solver | Photomath | Step-by-step solutions | No | Yes (limited) |
| Practice generator | Skoolskill | Daily quizzes from your notes | Yes (scan to quiz) | Yes |
Each lead app earns its category — the table is about fit, not which is “better”.
How to build a two-app study stack
Most students get the best results from two apps, not five, chosen to cover the two phases of studying. The first phase is intake — getting facts and concepts into your head — and the second is output — proving you can produce them under exam conditions.
A practical stack looks like this:
- Intake app: Khan Academy if you need a topic taught from scratch, or Quizlet/Anki if you mainly need to memorise terms and vocabulary.
- Output app: Skoolskill, generating exam-style questions from your own notes and grading them so you can see whether the intake actually stuck.
The common mistake is owning only an intake app and assuming that re-reading or re-watching equals revision. It doesn’t — retrieval under test conditions is what moves a grade. Pairing one intake tool with one output tool covers both halves without app overload, and keeps your daily routine to a single short practice session rather than juggling several.

Who should pick which
- Pick Skoolskill if your problem is doing daily practice on your own notes and past papers, marked like the exam.
- Pick Quizlet if you want the biggest ready-made flashcard library and study games.
- Pick Anki if you want full control over a spaced-repetition system you build yourself.
- Pick Khan Academy if you need to learn a topic from scratch, free, via video.
- Pick Photomath if you mainly need to see how to solve specific maths problems.
When a study app isn’t the answer
- You need motivation and accountability more than content — a human helps where an app can’t.
- You have a learning difference that needs tailored support.
- You’re so far behind that you need structured catch-up teaching first, then an app for practice.
