SketchCalc

SketchCalc is a visual calculation workspace for people who think through numbers, notes, and spatial logic.

Unlike a standard calculator, SketchCalc keeps context visible. Write calculations, add notes above numbers, move items around the page, and organize your reasoning like an analog drafting notebook.

Designed for architects, designers, engineers, students, makers, and visual thinkers, SketchCalc combines a notebook-style canvas with precise digital math.

Features:
• Notebook-style calculation workspace
• Text notes and calculations on the same page
• Parentheses, powers, percentages, square root, and negative numbers
• Copy and paste support
• Movable notes and calculation items
• Light and dark mode
• Apollo 11-inspired onboarding example
• Ad-supported free workspace

SketchCalc Pro unlocks unlimited pages, page naming, PDF export, an ad-free workspace, and an extended visual calculation workflow.

Stop losing context. Start calculating visually.
