Photomath vs RemNote

Photomath is a mobile app for working through math problems on Android and iOS. It can scan a problem with a device camera or accept input through its smart calculator, then show a step-by-step solution. It can handle word problems as well as other math questions, and a scan may offer multiple methods to choose from. Its listed subject range spans elementary math through college math, including algebra, geometry, trigonometry, statistics and calculus. Interactive graphs can be zoomed and tapped for information, with definitions available in context. The free Basic plan includes step-by-step explanations; Photomath Plus adds custom visual aids and extra “how” and “why” tips, with Animated Tutorials and teacher-approved definitions also listed as Plus features. A free trial may be offered, but a subscription trial converts to paid billing unless canceled before it ends. Plus is listed at $9.99 per month or $69.99 per year. Paid Services are billed through Google Play or the iOS App Store, and use is limited to personal, non-commercial purposes.

RemNote is a learning and note-taking app that turns notes, PDFs, and other sources into AI-generated flashcards, quizzes, and summaries. Its study tools include spaced repetition, practice quizzes, and card formats such as question-and-answer, fill-in-the-blank, lists, clusters, and image occlusion. Users can annotate PDFs and slides with highlights, drawings, and shapes, and source citations are available. Notes and flashcards remain accessible offline and sync when connectivity returns. RemNote offers desktop apps and mobile apps for iOS and Android. The free plan includes unlimited notes and flashcards and synced devices, plus 20 daily file uploads up to 8MB each and 250 monthly AI credits. It also limits free users to three annotated PDFs, five image occlusion cards, and one handwritten document. Pro is listed at $8 a month, and Pro with AI at $18 a month. RemNote was founded in 2020.
