What is Strix?
Strix is a digital engineering toolkit for mechanical engineers. It brings calculations, formula sheets, standards data, and reference tables into one application — replacing the workflow of searching through physical handbooks and scattered resources.
What tools and calculators are included?
Strix includes tools for beam deflection (15+ load cases), column buckling, bolt sizing (VDI 2230), weld sizing, gear ratio calculations, circlip reference data (DIN 471/472), cross-section properties, and a unit converter. On the reference side you get formula sheets for math and physics, a library of 200+ engineering quantities, 40+ physical constants, and a symbolic calculator with step-by-step solutions.
Is there a free trial?
Yes. The Personal plan includes a 30-day free trial. You get full access to all tools during the trial period. You will only be billed when the trial ends, and you can cancel anytime before that without being charged.
What is the difference between the Personal and Organisation plans?
The Personal plan is for individual engineers and includes all calculators, reference tools, and a personal notes workspace. The Organisation plan adds a shared team workspace, seat-based licensing, member invitations, and admin controls — designed for engineering teams and companies.
Can I use Strix on my phone or install it as an app?
Yes. Strix is a Progressive Web App (PWA), which means you can install it on your desktop, iOS, or Android device directly from the browser — no app store required. It works like a native app once installed.
What engineering standards does Strix use?
Strix references established industry standards throughout. The bolt calculator follows VDI 2230, circlip data covers DIN 471, DIN 472, and DIN 6799, and the cross-section library includes European steel profiles (IPE, HEA, HEB, HEM, UPN) with properties per those standards.
Is Strix available in Swedish?
Yes. Strix is available in both English and Swedish.
Can I edit formulas or write my own calculations?
Yes. Formulas and calculations in Strix are editable using a familiar, expression-based syntax. You can tweak built-in formulas, add your own variables, or write a calculation from scratch — then save it to your workspace and reuse it across projects and devices.
Can I save calculations and notes?
Yes. Every account includes a personal notes workspace where you can save calculations, references, and other material. Your notes are stored in your account and accessible from any device.
