SketchCalc combines a scientific calculator, a visual math notebook and a bill splitter in one workspace. Calculate, graph, sketch and organize your ideas directly on the page. No account is required for the core notebook. **SCIENTIFIC CALCULATOR & LINKED MATH** Work with fractions, percentages, powers, roots and trigonometric expressions. Connect calculations so dependent results can update when source values change. Explore supported algebra and step-by-step math solutions. **GRAPHS, SLIDERS & VISUAL NOTES** Plot functions, adjust values with sliders and keep graphs beside calculations. Add handwritten notes, pencil sketches, shapes and diagrams to build a readable visual record of your work. **BILL SPLIT & RECEIPT SCANNING** Divide restaurant bills and shared expenses. Add items and people, assign purchases, and account for tax, tips, service charges and discounts. Where supported, scan a receipt to help enter the bill. Always review recognized amounts before splitting. **SCAN & SOLVE** Capture or select an image containing supported math expressions. Review recognized symbols, explore available solution steps and add supported results to your notebook. Recognition and calculation are handled locally on your device. **SAVE & EXPORT** Keep your pages and project files on your device. Reopen your work and export supported content, including PDF. Some export formats and advanced tools require PRO or a rewarded unlock. **FREE & PRO** The Free version includes a first notebook page with up to 10 rows. Completing a rewarded ad can unlock a second 10-row page for 48 hours; its saved content remains on your device after the unlock expires. Selected advanced tools and Bill Split have separate rewarded access limits. Rewards are granted only after an ad is completed. SketchCalc PRO is a one-time purchase that removes ads and unlocks expanded pages, rows and tools. Availability of scanning and advanced calculations may vary by device and operation. Check important calculations and recognized text before relying on them.

Verdict
The clearest difference is in-app purchases: CalcDraw at none against SketchCalc's 1. CalcDraw also leads on ads (none vs shown). SketchCalc's advantage is update cadence (every 2 weeks vs monthly). On price, device support and iOS requirement there is nothing between them.
