What it does
Five shapes
Rectangular slabs, round slabs, footings, columns, and steps on one screen. Dimensions go in, results come straight out.
Full mix design
Pick a grade from M10 to M50 or enter a custom ratio, then read the breakdown for cement, sand, gravel, and water.
Instant bag counts
See exactly how many bags the pour needs, alongside volume and cost estimates.
Imperial and metric

Questions
Is the app really free?
Yes. Mix is free to use with no subscriptions, hidden fees, or account registration.
Does it work offline?
Yes. Every calculation runs locally on your device, so you can use it on site without an internet connection.
How accurate are the results?
Mix uses standard geometric formulas and concrete mix design principles, plus a customizable waste factor (10% by default) for real pouring conditions.
Ready for the next pour
Run the numbers before you order, so you are not short a bag or paying for half a yard you did not need.
