EqualMath vs PageNote

Designed for Apple Pencil and iPad, version 3.1.8 now lets you quickly sketch with basic elements — points, lines, and shapes — to support theoretical exploration. Function graphs are included. Core features are free.But includes some paid features: linked point function, hidden circle and color block function, creating more than 5 folders, radian display in the plane coordinate system, 3D coordinate system, vector arrow, parametric equation, water drop coloring, etc. Beyond geometry, sticky notes are central: pin them to the canvas to highlight key steps, while unwanted ink can be erased to keep your workspace clean. ### Additional Features 1. **Handwritten uppercase letter recognition** – instantly names vertices as you draw geometric figures. Turn it off to use freeform handwriting for names. 2. **Export to Photos** – one-tap export with no watermark. 3. **Import from Photos** – insert an image directly onto the canvas (display only, no recognition). Supports importing PDF files. 4. **Points, lines, and shapes** – select what you need. A key highlight: drag from a vertex of any shape to create a new point – no need to open the menu. 5. **Lasso tool** – select content or activate locked geometry elements. For points, three selection methods are supported: draw a line near the point, draw a line that passes through the point, or draw a small circle around it. 6. **Paint bucket** – fills enclosed geometric figures and regions, dynamically sensing surrounding areas to some extent. 7. **Infinite canvas** – the canvas automatically expands in all directions as you add more ink. 8. **Function graphs** – plot single-variable expressions and parametric equations. 9. **Multi-point linkage** – explore geometric problems involving multiple moving points. 10. **3D coordinate system** – the current release introduces a 3D coordinate space where you can place points and set spatial coordinates. 11. **3D Geometric Shapes: triangular prism, quadrangular prism, cylinder, cone, triangular pyramid, quadrangular pyramid Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

PageNote turns the lecture PDFs you already have into per-page study notes, and lines your problem sets up with how far your course has actually got. WHAT IT DOES • Per-page notes — open a lecture PDF and get a one-line summary, the key points, the terms that matter, and "how it's tested" for the page you're on. Not a summary of the whole deck: page by page, following your reading. • Problem sets that follow your progress — import a problem set and PageNote maps each question to the pages that teach it. Tell it how far today's lecture got — just the page number — and it pulls out the problems you can actually do now. • Write it out, then get it marked — do one problem per sheet with Apple Pencil, then ask for marking. It reads your working, says which step went wrong, and keeps what you missed in a mistake book. • Every problem, by subject — all of them in one place, filtered by To do, Wrong or Repeated. • Handwriting on the slides — annotate with Apple Pencil and export a PDF that combines the original slides with your handwriting. • Review — wrong answers and terms you keep forgetting go into one queue, spaced 1 / 3 / 7 / 14 / 30 days. One card at a time: think first, then flip. • Mock exam — before a test, pull a set of questions from a page range, with an optional timer. Mark yourself at the end; anything wrong goes into the mistake book. • Exam reminders and a Home Screen widget — set an exam date and get one reminder 7 days before and one the day before; the widget keeps the countdown and today's workload in front of you. FREE, AND WHAT COSTS MONEY Reading, Apple Pencil annotation and PDF export are free forever. Generate 10 pages of AI notes free on your first document — no key, no signup. After that a subscription covers the AI, you pick which model runs, and you can cancel any time in Settings. SUBSCRIPTION DETAILS • PageNote Standard — monthly, or one semester (6 months), auto-renewing • PageNote Advanced — monthly, or one semester (6 months), auto-renewing • PageNote Pro — monthly, or one semester (6 months), auto-renewing In mainland China, Hong Kong and Macau there are two tiers only (Standard and Advanced): fewer AI providers are reachable there, so both tiers run the same set of models and differ in monthly credits, and they are priced lower than elsewhere. Everywhere else there are three tiers, each unlocking a further class of model. Standard comes with a 7-day free trial, once per Apple ID within the subscription group; Advanced and Pro have no trial. When the trial ends it converts automatically into a paid Standard subscription, charged at the Standard price for your region. To avoid being charged, cancel in your Apple ID account settings at least 24 hours before the trial ends. Prices differ by region and may change over time. The exact price and period for your region are shown in the In-App Purchases list on this App Store page, and on the subscription screen inside the app, before you confirm. Payment is charged to your Apple ID at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period; your account is charged for renewal within 24 hours before the period ends. You can manage or cancel a subscription in your Apple ID account settings after purchase. Any unused part of a free trial, if offered, is forfeited when you buy a subscription.

No conversation thread, no history between questions, and off-topic questions are declined. Each answer is saved as an annotation on that page, not as a chat log. AI can be wrong. Check anything that matters against your lecturer's material.
