UNIQUE EASY TO USE INTERFACE
Just look at this! It's an easy to use formula solver built natively for your iOS device. It displays a clean image of the equation in question and those text fields eagerly await your input. Just leave any one text field empty and iEquals does the math for you.
But what are those on the right? Are those actually units? If this gets you as excited as it gets me, then you've really got to check out the next feature below. 
GOT UNITS? YES, OVER 400 UNITS OF 25 TYPES
Life's problems are full of units. Now you can feel confident when you submit your next assignment after double checking your answers with iEquals. I remember when a physics teacher once told me that "A number without units is meaningless" and was he ever correct!.
This is where many of the other formula solving apps fall short  they simply provide you with the ability to calculate an answer but then they leave the units up to you. So there you are with a mobile formula solver in one hand and an archaic calculator in the other, basically onestep forward, and onestep back.
Now that's not what iEquals does, iEquals give you a comprehensive list of over 400 units in 25 unit types to choose from so you don't get those pesky conversions wrong. And iEquals performs these unit conversion right there on the spot, accurately, every time, so you don't have too.
