Calqira
AvailableA calculator that does far more than calculate.
Everyday maths, geometry, statistics, conversions and practical tools in one simple, pleasant interface. Ten modules, eight themes, seven languages.
The studio
Croxal, Digital Studio
Simple, useful, carefully crafted apps.
Croxal is the name under which I design and publish my mobile apps. The approach is deliberately small-scale: few apps, but each one thought through in detail, from the first screen to the last icon.
Calqira is the first app released under this name. Others will follow in the same spirit: quiet, fast, pleasant to use every day.
The site you are reading is deliberately light: no ad tracking, no third-party services, no framework dependency. It is updated by a simple file transfer.
Croxal is a development studio name, not an incorporated company.
Simple above all
No account, no tutorial: the app is usable from the very first second.
Light and fast
An app that opens instantly and uses almost nothing.
Detailed by hand
Spacing, colours, icons: every screen is drawn, not assembled.
The catalogue
The apps
The list is deliberately short.
Next app
Coming soonThe studio releases little, but releases it well. The next app is being designed.
