Give every number a meaning. OmniCalc is a calculator with notes, saved history, and one-tap totals, so you can keep track of both the answer and how you got there. ADD NOTES TO NUMBERS AND CALCULATIONS Label individual numbers as price, quantity, shipping, or anything else you need. Add a note to the whole calculation to make it easy to understand later. TOTAL MULTIPLE RESULTS Keep related calculations on one page and add up all results with one tap. Useful for grocery lists, travel expenses, and everyday spending. KEEP PROJECTS SEPARATE Create separate calculation pages for costs, quotes, and budgets. Enter your own numbers and expressions, then keep the steps for future reference.

EVERYDAY MATH, YOUR WAY Use arithmetic, parentheses, and percentages with live result previews.

Verdict
The clearest difference is ads: OmniCalc at none against Sevigintuple Calc's shown. OmniCalc also leads on update cadence (every 3 days vs every 2 weeks). Sevigintuple Calc's advantage is iOS requirement (15.8.3 vs 17.0). On price, in-app purchases and device support there is nothing between them.
