"Absolutely brilliant app! As a small builder doing domestic extensions and foundations, this app saves me hours every week. The offline functionality is essential - I work on rural sites with no signal and can still calculate everything I need. Worth every penny (actually free which is incredible)."
"The AR measurement feature is a game-changer. Point your phone at a foundation trench and it calculates the concrete volume automatically. Incredibly accurate and saves so much time compared to manual tape measurements. My whole team uses it now on commercial projects."
"Finally built my patio and garden wall myself using this app for all calculations. Super easy interface - if I can use it, anyone can! Got the exact amount of concrete delivered, no wastage, no shortages. The cost estimator helped me budget the whole project accurately."
"The job management system is brilliant for keeping track of multiple projects. I can send PDF estimates to clients directly from the app, professional looking and accurate. The cloud sync means I can start a quote on my phone and finish it on the iPad in the office."
