Calsee is a free calculator for iPhone, iPad and Android that generates a new theme every time you swipe: Liquid Glass, Neo-brutalism, Cyberpunk, Paper & ink and more. It's also built for everyone: hold any key to learn what it does, switch to a left-handed layout, and every theme is contrast-checked, with a 7:1 accessible mode. History with search, notes and CSV export, and the amount in words under every result. No ads, no account, no tracking.

Hi Product Hunt! 👋 I'm Abhilash, the maker of Calsee.
I've spent a lot of time on theme management: light, dark, festive and high-contrast themes, all kept in sync by hand. I wanted to see if themes could be generated instead, and a calculator felt small enough to try. In Calsee a theme is a single seed: swipe the display and the app works out the colours, key shapes, fonts, press motion and even the click sound, across 12 styles from Liquid Glass to Neo-brutalism.
Once the themes worked, I kept asking "who might find this hard to use?" That led to the parts I'm proudest of:
Hold any key to learn what it does, with a worked example you can watch
A left-handed layout that moves = and the operators to your thumb
Every theme is contrast-checked (4.5:1 minimum, 7:1 in Accessible mode), operator keys are checked against simulated colour blindness, and every key has a screen-reader label
History you can search, annotate, pin and export as CSV
The amount in words under every result (lakh/crore or million/billion, in English or Hindi)
It's free, with no ads, no account and no tracking, and it works fully offline. Built with Flutter for iPhone, iPad and Android.
I'd love your feedback: which theme style you like best, what feels off, and what you'd want next. Happy to answer anything about the theme generator too!
