No ads
Our apps are paid for by the people who use them, never by advertisers.
Independent app studio
Small apps, made carefully.
DK Squared Studio builds clean, focused mobile apps for iOS and Android. No ads, no tracking, and no dark patterns — just software that respects your attention.
Our apps
Out now, and coming soon.
DK Sudoku
A clean, ad-free classic Sudoku with six difficulty tiers, graded by the logic each puzzle actually requires.
DK Field Camera
A professional GPS camera for fieldwork. Every shot gives you the original and a copy stamped with location, address, time, project and your own fields.
How we work
Three commitments.
Private by design
We don't run analytics or advertising SDKs, and we run no servers that collect your data. Each app has its own privacy policy.
Works offline
Our apps are built to work without an account or an internet connection.
