One studio, built by someone who uses the tools.
Inverse Square is an independent software studio based in the United Kingdom.
What we make
Focused desktop and browser software for people who make things: parametric CAD, simulation, 3D modelling, optics and printing on the engineering side, and painting and photo tools on the creative side. We also make I Want To Talk, an AAC app that gives people a voice.
Alongside the paid products, Labs has free tools you can use straight away in your browser, with no sign-up.
How we sell software
- One-off licences, no subscription. You pay once and the version you bought keeps working. Updates within that major version are included.
- Linux, Mac and Windows where we can, and the browser where it makes sense.
- Your files stay yours. Our apps work on files on your own computer, in open or standard formats wherever possible.
- A real person answers. Support comes from the people who write the code.
Payments are handled by Lemon Squeezy, our reseller and merchant of record. They take the payment, handle sales tax and VAT, and issue your receipt and licence key. See the terms and licence and the refund policy for the details.
Why the name
Light, gravity, sound and radiation all fade with the square of distance. It's one simple rule that runs through rendering, simulation and optics, which is most of what we build.
