Comments on Construction Calculator A1 for Android

★★★★☆ shivtej jagtap · Apr 17, 2026

GI rectangle pipe with various thickness are not included for calculation. It basically used in warehouse construction.

★★★★★ Shubhrashree Maji · Apr 3, 2026

Excellent App For Beginners as well as for all Experience Professionals of Civil and Structural Engineering

★★★★★ Roshan Ghade. CT · Mar 28, 2026

It’s a great app overall. Earlier, it was quite difficult to calculate quantities on-site, especially when there was no pen and paper available. Now, everything has become much easier—I can quickly calculate diagonals, concrete quantities, reinforcement, excavation, and much more. The ability to share calculations with co-workers is also very helpful. This app is extremely useful for building contractors as well as for site labor. Really great job—highly recommended!

★☆☆☆☆ MS-EDS · Mar 29, 2026

I recently downloaded the app and use it for my projects. And I am using the pro version. It seems, there is a bug or a problem with displaying the "Indian currency" symbol while printing as a PDF format. Particularly, while using "construction cost" option. Please fix it ASAP, it looks unprofessional when sending the invoice to my clients.

Trust & Safety: Uses standard Android permissions (Internet, network state, foreground service, storage access, notifications) and integrates advertising/analytics libraries (AdMob, MoPub, Facebook Ads) along with a dynamic receiver not exported. This combination is common for market tools; users should review privacy terms to understand data handling for ads and analytics. Overall, permissions align with typical utility apps and feature sets for offline calculation.
