Not great!

Paid to remove the adds & you still get them!!!

Only works in ft & inches NOT metric!!

Waste of £1.99

Complete con!

Waste of time as the app does nothing other than try to sell you a more advanced version or link you to websites to spend money. Apple should not allow this kind of rubbish in their App Store!

Doesn’t work properly!

I’ve upgraded but the Slab feature doesn’t work, every time you try and put the depth measurement in the answer box disappears, also it closes down when ever it feels like it and the upgrade doesn’t get rid of the annoying pop-up ads... please fix these bugs otherwise it shouldn’t be in the App Store, one has to wonder if Apple checks the apps before they sell them!????

Junk

Paid $3 to get the adds to stop, and open the other calculators, I still get adds and the calculator give you such large fractions, I don’t even know what they are. For example it gave me 66’5-333/500”
What the heck is 333/500” of an inch

Waist of money.

Paid 1.99 to get rid of adds and it didn't work.
