Common questions

Is the calculation engine ISO 5167 compliant?

Yes. The engine implements ISO 5167:2003 parts 1-4 and ISO TR 15377. Discharge coefficients, expansion factors, and validity ranges follow the published equations exactly.

Can I try before buying?

Yes. The free trial lets you run full calculations without creating an account. No credit card required.

What counts as a seat?

One seat = one user account. The person who purchases gets the first seat and is the workspace admin. Add more seats for colleagues during checkout or later.
