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.
Pick a category to see its tools.
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 needed. Your calculations and project data stay on your device; only comments and follows you choose to send are stored.
Video walkthroughs of the RIKAZ tools and the Site Safety Series, in English and Arabic.
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.
