StudyAce
Read full descriptionHide full description
Understand the question in front of you tonight. Still know it on the day of the exam. StudyAce is built for both halves of studying. Solve gets you unstuck: point the camera at the question, or type it in. Learn makes it stay: flashcards, practice tests and a review queue that build themselves from whatever you're studying. WHEN YOU'RE STUCK ON A QUESTION Snap a photo of the problem, or type it with the built-in equation editor and math keyboard — fractions, exponents, integrals, no fighting the keyboard. The step-by-step solution streams in as it's written: the working, the reasoning, the line you skipped. Not just a final answer. Still fuzzy? Ask AI tutor chat, as many times as you need. Why did that sign flip. Do step 3 again. Give me a similar one. Every equation comes back properly typeset, so the math reads like a textbook instead of a text message. Algebra, calculus, geometry, physics, chemistry — and plenty that isn't math at all. WHEN A TEST IS COMING Type a topic and get flashcards on it. Or hand over a PDF — lecture slides, a scanned chapter, your own typed notes — and StudyAce reads it and turns it into a deck of flashcards, multiple choice and true/false questions, and a full practice test you can sit like the real thing. Nothing to type out by hand. Then the review queue takes over. It runs on spaced repetition, so each card comes back right before you'd forget it. Ten minutes a day beats the night before. Drill a deck in a spare five minutes, or sit the practice test end to end the weekend before. Review works offline, so the bus, the queue and the waiting room all count as study time. WHEN YOU HAVE TO WRITE IT UP AI writing tools for essays, summaries and drafts — something to start with when the page is blank, and a way to tighten it when it runs long. WHEREVER YOU STUDY Native apps for iPhone, iPad and Mac. Snap a question in class on your phone, run the review queue on your iPad on the way home, write the essay on your Mac with the whole topic in front of you. No sign-up, no account — open it and start. WHO IT'S FOR • High school and university students, working through homework and exam prep • Self-learners with no class and no teacher, studying from PDFs, textbooks and lecture notes • Anyone who's fine in one subject and stuck in another: math and science, and just as much languages, history, biology and economics STUDY HONESTLY StudyAce shows you the route to the answer so you can walk it yourself next time. A tutor that explains its working, not an answer key to copy. STUDYACE PRO You get 3 free tries.

Verdict
The clearest difference is in-app purchases: Zachet at none against StudyAce's 3. Zachet also leads on iOS requirement (17.0 vs 26). On price, ads and device support there is nothing between them.
