1. 5/5By far the best one I’ve tried

   I use this app every single day. I’m a commercial designer and regularly have to multiply and divide dimensions for my work and this app makes my life so much easier. I like that you can change the color and theme of the app as well to make it a little more fun and customizable. If you’re not familiar with these types of apps you’ll wanna play around with it to get the hang of it, but that’s to be expected. I picked it up quick and I know you’ll be happy with this app if you use it. Edit: I’ve been using the app going on 3 years now I believe? I STILL use this app every single day for my job and absolutely love it. To the developers, please don’t ever get rid of this app. I feel like every time I (rarely) fall in love with an app, it somehow gets removed from the App Store. This app is fantastic and I don’t want to ever not have it.

2. 5/5Best for woodworking

   I really like this app. My go to calculator. At first I thought I would have to learn to live with the wood looking theme, but it’s changeable to 8 or so other colors I really like how you can limit the fractions to something on your ruler. You can have it get very precise or say have it round to the nearest 1/32nd or 1/16th. At the same time it shows you the decimal equivalent and you can cycle the result to centimeters, millimeters and more, then back, or not go to metric at all. The data entry is different than all the others I’ve tried. You enter the feet in the top section, inches in the section below that, and select the fraction from a scrolling menu. The scrolling fraction menu is configurable and limits fractions to those found on a ruler. You can change the imperial entries to metric and have imperial results and metric at the same time, or just one or the other. It has proven very handy for me working with it in split view on my iPad along side a set of plans. Very nice app, A+

3. 4/5Everything I wanted and more but...

   I’m in no way in the construction industry, but I am building a new house. Having just received the survey, I wanted to do some calculations on my current square footage, the overall length and width of my existing home etc... nothing major, purely low volume stuff. The app worked perfectly, doing everything I asked of it and allowing me to do more (the triangle calculator was handy for getting an idea of the size of my new homes roof)... tho (and maybe I missed it), I would have liked to be able to get a slope/pitch ratio from my input of the angle (I actually couldn’t get any of the pitch x/y buttons to work), minor detail as I’m setting my roof by the angle of my latitude for a solar PV array. One star is lost because I *wanted* to toss the few dollars your way for making just the right app available for me at just the right time. Problem is, every time I click on the “Remove ads” button the app crashes... this is a 6th gen iPad with the latest iOS installed so... no cookies for you. If there’s another way (a pay for, ad-free version on the AppStore say) do let me know as I really appreciate the effort that went into this !! While we’re at it, it’d be nice if we could change the font color as well as the bg color... I do love a black bg with green text for that old terminal feeling !!

4. 5/5Customer Support

   When it comes to a computer or phone product, be it hardware or software, customer service doesn’t make the product work better but it is, in my opinion, what marks the creator or company as to whether they truly care about ‘the customer’. Customer support for this app is top notch! The developer deems it important enough to quickly reply when a customer has an issue or problem with the app. That says a lot to me! I’m no math whiz so this app has come in very handy when I’m attempting to create my latest woodwork or metal project. Thank you for a great little app! 🤓

5. 5/5Great and Easy to Use

   I am a CAD drafter/ detailer and I originally downloaded the free version and found myself using it constantly so I decided to buy the Lifetime version because I think it’s worth it. As you use it you start quickly understanding how it works. If I had to improve one thing it would be to make the fraction scroll buttons, all in different colors so they can be easily identified. 32nds in one color, 16th another color, 8th another, 4th another and 1/2 another. Other than that. Perfect.
