Gives the answer in fraction and decimal. Needs updating **Developer response:** We couldn’t agree with you more. We are happy to say that after a few rewrites of the application, we are back and stronger than ever. We now support all device sizes, added a history view and a few options in settings with more coming. We also proudly display our impact on Kiva.org thanks to your purchase. ### 5/5 — Awesome app! But... *2013-10-26* Is it at all possible to create a larger clear button? My iphone is sporting a Griffin protective cover which is very much needed for fighting wildfire and all other outdoor and dirty, wet conditions The cover design is smack dab too close to the "x" Other than that, this bugger has come in handy many times. **Developer response:** Thanks for the feedback. We’ve updated the app to support all screen sizes as well as added more padding to the clear button. Although, this button is now only needed (and visible) when you’re in the middle of an equation. ### 5/5 — Simply the best *2013-10-01* It is simply the most magnificent application my apple device has ever had the pleasure of downloading onto its platform. ### 1/5 — Abandon ware ??? *2013-09-03* Great app for basic fraction calculations only. It does what it says calculates fractions and is easy to use. It has not been updated in over a year and will not go full screen on my iPhone 5 it is only a mater of time before it will not work. I would give it 5 stars if they would update it but it is useless if not. **Developer response:** Sadly we did take a several year hiatus with the app. (College life and the new working world was a worthy distraction.) We are happy to say that after a few rewrites of the application, we are back and stronger than ever. We now support all device sizes, added a history view and a few options in settings with more coming. We also proudly display our impact on Kiva.org thanks to your purchase. Over the past 10 years we’ve been able to make an impact on 3,866 borrowers in 59 countries. ### 2/5 — Needs some adjustment *2012-12-06* Easy app to use but 17/24 does not help when using a tape measure. Wish there was a way to tell it that 16ths are the limit. **Developer response:** This has been a popular request and we’re happy to say these options are now here. After a few rewrites of the application, we are back and stronger than ever. We now support all device sizes, added a history view and a few options in settings with more coming. We also proudly display our impact on Kiva.org thanks to your purchase. ### 5/5 — Amazing app! Love it!! *2012-11-15* Fantastic app! Just what I was looking for and better! A+! ### 5/5 — Fantastical *2012-04-11* Just exactly what I needed no no less ### 5/5 — Great little calculator! *2012-02-19* Very easy to use and the only app I've found (after 7 or 8 tries) that could divide an inches measurement by a whole number. I was about to give up, but this app saved the day … and will save me lots of time and headaches! Love it! ### 5/5 — Great bare bones fraction calc app *2011-12-30* I use this app everyday in my woodworking business.Incredibly convenient and easy to use for measurement calculations such as multiple 16ths and 32nds and of course fraction/decimal combos.Not a very complex/do any geometric equation/all encompassing construction app but perfect for quick reference. Like others have reviewed, cons are no backspace and no metric system, but if you're working exclusively in standard measure this app is very helpful and accessible with basically no learning curve. ### 5/5 — Amazing App! *2011-12-05* I highly recommend this app. It is very helpful. My only problem is no backspace button, so be careful when typing. ## Frequently asked questions about Fraction Calculator Pro ### What kind of calculations can Fraction Calculator Pro perform?
