A game changer for Every Engineer.

I’ve been using Construction Calculator A1 on my MacBook and iPad , and it’s been an absolute game changer. The app is fast , clean, and incredibly useful for daily site calculations.
Whether it’s Area, Volume, Steel weight, or Unit conversations, every features is well-organised and easy to access. I especially love the dark theme and offline functionality. The rebar and concrete mix design tools are spot-on.
Great to see support for both metric and imperial units, and the interface adapts well to the larger screen on mac tabs. This app has easily replaced multiple tools and saved me hours of manual work.
Highly recommended for civil engineer’s, contractors and site Supervisers.

Response from developer

We sincerely apologize for the inconvenience caused and understand your concern regarding the purchase. The app offers a one-time lifetime purchase, and in some cases, the purchase may not reflect immediately due to store sync issues. Kindly ensure you are logged in with the same account used for the purchase and try the Restore Purchase option available in the app. If the issue still persists, please contact us at our support email with the payment screenshot, and we will assist you in resolving this at the earliest. Thank you for your patience and for bringing this to our attention.

Unit issue

The area calculated is always shown in (metric)sq mtr even if you choose (imperial) sq ft as the dimensions….No provision to change the unit…

Thank you for reporting this issue. The unit display has been improved in our latest version. We request you to please update the app and check again. Thank you for your feedback and support.

Best civil engineering app

Very easy to use. App works perfectly. Also worth to buy PRO version.

Response from developer

Thank you for the great feedback We’re happy to know the app is easy to use and working well for you. Thank you for recommending the Pro version and for your support.

Basic calculations are wrong

Calculations as simple as finding the area of a 4 sided object are false. Wouldn’t trust this if it were the only calculator available.

Response from developer

Thank you for sharing your feedback. The area calculation for four-sided shapes follows standard formulas and works correctly when inputs and units are selected appropriately. In some cases, confusion can occur due to unit selection or input method. We request you to please check the latest version and verify the inputs and units used. If you still face any issue, kindly contact our support team with details so we can review it further. We’re always happy to help clarify and assist.
