Common questions
Does the app need an account?
No. Everything stays on your device.
Does the app work offline?
Yes. Core calculations and saved recent results do not require a
network connection.
Does the app provide engineering approval or strength certification?
No. The app is a planning reference only. Always confirm local
requirements, supplier guidance, and any structural or inspection
needs before you mix or pour.
What units does the app support?
Version 1.0 supports liters, cubic meters, and cubic
feet for the target batch size.
Is the cement bag count exact?
No. Bag output is shown as an assumption-based estimate so you can
sense-check a batch quickly on site.
