Hey everyone 👋
I’ve been working on a Nothing OS inspired calculator, and the whole thing was built and tested entirely on my phone. This started as a small experiment, but I ended up spending a lot of time trying to make it feel clean, calm, and something that could realistically fit into the Nothing ecosystem.
Along with normal and advanced calculations, I’ve added measurement and unit conversions directly into the calculator. It covers things like length, mass, time, speed, pressure, force, energy, power, area, volume, data, temperature, and currency, with more than just the basic units. The idea was to keep it simple to use enter a value, choose the units, and see the result instantly without turning it into a cluttered tool.
Design wise, I tried to stay close to Nothing’s style: dark UI, rounded elements, subtle red accents, and Noto Serif typography, with smooth animations and light feedback so it feels a bit more physical when you use it. It also includes calculation history, a small info page, and automatically follows the system’s light or dark mode.
Since this is still a work in progress and was made completely on mobile, I’d really appreciate any feedback. If you notice bugs, rough edges, or things that don’t feel right, please point them out so I can fix and improve them. I’d also love to know if this is something you’d actually want to use, or what you’d expect differently from a Nothing style calculator.
Thanks for reading 🖤
