About this app

Looking for a civil engineering calculator and site logbook for construction projects?

KFirst is an offline engineering workspace designed for civil engineers and site supervisors in Kerala. It combines essential civil engineering calculators with a powerful site logbook and project tracking system for real construction sites.

Create clear daily progress reports (DPR), record work done on site, track materials and labour, and keep all project information organised in one place.

Work confidently even without internet. KFirst is built for real construction sites where network connectivity is often weak or unavailable.

📌 What KFirst Helps You Do
