Ready-to-use calculators
Finance, business, everyday, travel, home, math, health and conversion calculators are available from the start.
Calculate what matters.
Build what you need.
CalcLasso brings useful calculators into one clean app and lets you create your own reusable calculators when a ready-made one does not fit.
Build your own
Define inputs, create a formula, test your calculator, save it and reuse it whenever you need it.
Fast, focused search
Quickly find calculators by name, category and related terms without digging through menus.
Simple by design
CalcLasso v1.0 does not require an account. Your custom calculator definitions and entered values stay on your device unless a future feature explicitly tells you otherwise.
