Win

Win is an all-in-one utility app that earns its place on a developer's phone, the number base converter handles the four systems used in code and hardware, while nine other tools cover the rest of daily life. The number base converter is the developer highlight: enter any value in binary, octal, decimal, or hex, and the other three fields fill in simultaneously, no separate conversion steps, no copying between fields, just one entry and four results. The percentage calculator adds quick computation for data and business contexts: calculate a percentage of a value, find what percent one number is of another, apply a percentage change, or reverse-engineer an original value from a known percentage. The password generator rounds out the security toolkit: configure character classes and length, view a real-time strength rating, copy the result, and access a history of the last 10 generated passwords, all stored locally on the device. Win is completely offline with no account required, all 10 tools are available immediately from the first launch with no setup needed.
