Rethiq

Study notes, handwritten maths, practice and revision in one place, on iPad and iPhone.

• Typed notes, Apple Pencil drawing and LaTeX equations, all on your device
• Import PDFs, Word, PowerPoint, text, Markdown and images
• Works offline without an account; a free cloud account adds sync, practice, spaced reviews and study plans
• Optional cloud AI that explains your own sources with citations. Its feedback is a suggestion, never a grade

Rethiq is in testing and not yet on the App Store.
