Makes my job much easier!! Thank you for the amazing free app!! ### 2/5 — Where’s metric *2017-11-14, version 2.0.2* Got this app but it needs the ability to switch to metric as most Concrete companies here in Canada are dispatching Concrete in meters NOT yards. ### 5/5 — Update *2017-10-16* Need update ### 1/5 — No good!!!!!! *2017-10-15* Need to update your app for ISO 11 ### 5/5 — Please update for new iPhone update *2017-10-13* I use this app multiple times a day and I love it. Very accurate. Need to update for new iPhone software update. Please hurry ### 5/5 — Contractor *2017-10-10, version 1.0* Excellent results every time ### 5/5 — Great app, *2017-10-08* Great app! Just it doesn’t work anymore without the new update that happened to all I-Phones iOS 11 Please fix it. ### 1/5 — Use at your own risk! *2014-07-12* I calculated a concrete pour using this app, and came up painfully short (1 yard short). Talked to the concrete supplier and their numbers were much higher. I verified the numbers from the concrete supplier with a different calculator. This app is not accurate! Costing me hundreds in time and additional delivery fees. BEWARE! Even though this a visually appealing app it is worthless because the calculations are wrong. ### 2/5 — Ozinga *2012-12-09* Kinda useless. Most idiots can calculate cubic yards. Looking for an app that will calculate bags of concrete needed ### 5/5 — Contractor *2012-05-21* Great application from a great company. Keep up the great work. ## Frequently asked questions about Ozinga Concrete Calculator ### How does Ozinga Concrete Calculator help with project planning?
