A Platform for Applications and Programs
Engineering calculators, general apps, and educational tools — all in one place. Standards-based, bilingual, offline-ready, and free to use.
Filter by domain to find what you need. Live tools open instantly; the rest dock here as they ship.
Every tool switches between English and Arabic with full right-to-left support.
Install once and keep working with no signal — on site, at home, anywhere.
Engineering tools follow ASME, AWS & API, and every tool is built on trusted, verified references.
No accounts, no tracking, no data collected. Everything stays on your device.
Install RIKAZ apps on Android for full offline access on site — no browser, no signal needed.
GET IT ON Google Play
Built on real field experience — construction on major oil and gas projects across Saudi Arabia, Kuwait, the UAE and Egypt. Every calculator exists because the job needed it first; each one is published so other engineers can use it too.
Like the platform, follow new releases, and share your thoughts.
