Betxico

Betxico is a utility toolkit built around a two-mode calculator that handles everything from grocery math to physics homework, paired with nine other everyday tools in one clean app. Switching between standard and scientific modes is instant, the same history panel carries across both modes, so you never lose track of expressions you've already evaluated. The history panel stores the last 10 calculations in sequence, with each expression and result visible at a glance, and a copy button available on every entry so you can reuse any prior result without retyping. The percentage calculator integrates naturally with the math workflow: find what percent a value is of another, calculate discounts and markups, apply percentage changes, or reverse-engineer the original value before a percentage was applied. Betxico is an offline-first app requiring no account or internet connection, all 10 tools are fully functional from the first launch.
