FAQ

Good to know

Are these calculators really free?

Do they work offline / on mobile?
The tools are lightweight and run entirely client-side, so they load fast and work great on phones in the field.
Who builds INTI?
Working photo & video people. Each calculator ships with the real formula and a worked example — so you can verify the math, not just trust it.
Will there be more tools?
Constantly. The roadmap already covers 30+ calculators across cameras, exposure, storage and post-production.
