Go Calc 4+

I'm always in need of the functionality provided by this application. One example has to do with walking distance as calculated by many of the gps applications. Most gps apps provide distance, but don't seem to calculate it correctly if you are going up hill - even though they should be able to by combining the distance with the altimeter. With this simple app, I can create a formula such that base=gps distance, angle=whatever the up or down angle is, and then do "actual distance = base/cos(radian(angle)) and have the result - quickly and easily. I could probably even create a formula to calculate actual calories burned based on the up and down angle. Likewise with interest calculation... and I didn't even have to write the formula because it is already built in. The spin-wheels make it easy to access functions (like the radians, and cos used above) and the built-in functions are ones that are commonly used.

Variables can be made and saved and then used in other functions. That's really handy.

Well worth the price. The only reason I didn't give it 5 stars is because I haven't used it long enough to find out if it had any real problems.

Every time there’s an IOS update, I have a few apps that have been abandoned by developers and won’t work with the new OS.

Most I wouldn’t care about or could easily replace — but not GoCalc. I’m always relieved when it still works, because I use it nearly every day. Still awesome.

I started simple, adding cooking conversions I use a lot. Then I added a few design conversions. But it turned into a mission-critical app when I created a set of formulas for all my estimating and billing. I'm not good at math, but by using the built-in apps as examples, and a little trial and error, I got them all working. Saves HOURS on these time-consuming tasks! Love being able to email the results to save with the paperwork.

Would give it 5 stars if you had the option to clear all variables at once, and if you could duplicate an entire calculation to use as a base for a new one.

I have been using this app for years. Use for work on a weekly basis. The last update seem to have created an issue. I can no longer edit a formula because the top header bar cover the equations. This also stops me from creating new calculators.
Please update correcting this issue.
Using 1st gen iPad mini.
I would easily give this app 5 stars if I could edit and create calculators again.
Please fix and thank you!
