Deleting this app. ### 1/5 — No longer works - abandoned *2023-06-01, version 2.0.3* Unfortunately this app no longer works (beyond being a simple calculator) and seems to have been abandoned by the developer. I would imagine that the paid version is in the sane condition. ### 5/5 — INCHcalc free *2021-04-08, version 2.0.3* I love this. I don’t need the advanced calculator. For free, this gets the job done. ### 5/5 — UPDATED: Needs updating! *2018-05-01, version 2.0.3* The developer has corrected the problem. Continue to love and use this app every day in my work. Great and needed app. [Old review: After the latest iPhone software update there was a message from Apple telling me that this App could cause my phone to work slower because the App is not updated for the new software. I see there is a new INCHcalc +. Is that compatible and if so, not too happy that I will need to spend $4.99 to replace an App I've already paid for.] ### 5/5 — A clean, simple, carpentry tool *2018-05-01, version 2.0.3* A great tool for carpenters, builders, or anyone who needs to perform simple calculations with inches and feet. This is not a conversion tool as most in the app store are. There's an ad for an additional paid upgrade which makes the calculator useless in landscape mode. Other than that, it's straight-forward, and performs as you'd hope. ### 4/5 — What about Pi *2018-05-01, version 2.0.3* Great tool for dealing with the obsolete system of feet and inches, but shouldn't there be a key for PI? ### 5/5 — The Best Ft/In Calculator Updated! *2017-10-02, version 2.0.3* I was afraid I lose my long time favorite foot/inch calculator when I updated to iOS 11 but no more. Thanks to the developer for the update! ### 5/5 — Great utility *2017-09-24, version 2.0.3* I’ve had this app just about from its first release. While I don’t use it everyday, it is handy to have around because it is intuitive to use and I don’t have to relearn anything when I need it. It is just an imperial calculator and does that job without fuss or annoying glitter. ### 1/5 — DO NOT BUY THIS APP!! *2017-01-16, version 1.7.4* The developer has not supported this app in years. They have released a new app and charge $4.99 for it instead of creating updates the existing one. If you buy this app you will get a message stating that it will slow your phone. I am not happy about buying an app which the developer does not support. I would expect them to do this on their next app as well. Buyer beware. ### 1/5 — Great on iPhone, awful on iPad *2014-12-23, version 1.7.4* This works great on my iPhone, but does not work on the iPad despite being listed as iPad compatible on the Apple App store web site. ## Frequently asked questions about inchCALC ### What does inchCALC do? inchCALC is an entry-level construction calculator designed to handle calculations with feet, inches, and fractions.
