Math Notes: iPad's Magic, iPhone's Nightmare
19 Jul
Summary
- Math Notes excels on iPad with Apple Pencil, struggles on iPhone keyboards.
- New iOS 27 beta Math Notes has navigation and input precision issues.
- Siri integration for Math Notes lacks deep contextual understanding on iOS.

The new Math Notes feature in the iOS 27 public beta promises advanced calculation capabilities, handling equations, variables, and unit conversions within notes. However, user experience on the iPhone is severely hampered by a difficult-to-navigate interface and finicky keyboard controls. Accidental spaces or slight timing errors can break the calculation pipeline, turning a potentially powerful tool into a source of frustration.
In contrast, Math Notes performs exceptionally well on the iPadOS 27 public beta, especially when paired with an Apple Pencil. The iPad's larger canvas and stylus support transform the experience, allowing for natural handwriting input and intuitive adjustments. This suggests the iPhone version is an unoptimized port of the iPad's design, highlighting a mismatch between the platform and the feature.
While Siri has seen AI upgrades, its integration with Math Notes on iOS is currently lacking. Users cannot easily dictate complex equations or dynamically generate variable chains via voice. Apple could improve the iPhone experience by introducing dedicated "Variable" pills for easier adjustment and "Link to Graph" context menus. Visual error indicators are also needed to help users troubleshoot broken calculations, improving its usability before the fall release.
