Help Us

DCSquare3D LLC is a small independent studio building apps and games — from the PrezTune instrument tuner, to the Chiringa Chop Chop kite-combat game, to the COSS-APP engineering tool.

Your donation helps keep these projects going. It covers infrastructure and hosting, annual domain registration, and the development hours that go into new features, improvements, and fixes.

We’re independent, with no investors and no monetization targets — we simply love building things that people enjoy and use. Every contribution, no matter the size, makes a real difference and helps us keep going.

Can’t donate? That’s completely okay — sharing our apps with friends and family helps just as much. Thank you for your support.
