Pros and cons of iEquals Free Formula Solver app for iPhone and iPad

iEquals Free Formula Solver app good for

I wish this was around before I graduated, would have made studying/homework a breeze! A must for any engineering student!
Quick, easy, and very user friendly! I highly recommend this app to all my friends. Useful for school, work, and everyday life. Great App!
This app is great, though it needs many more formulas. I recommend iEquals to high school students.
I am looking for this kind of app for a long time. So amazing and helpful. 5 star recommendation. Download it and u will love it.

Some bad moments

Ive found this app to be useful (kinematic equation 3 was exactly what I needed), but there is one thing that makes the app more than a little painful to use: every time I open the app I have re-select the various units Id like to use. In the case of kinematic equation 3 thats 4 fields that require scrolling through various possibilities before I can use the app. The next time I use the app I have to repeat that entire process. Another nice improvement would be to have Gs as one available way to display acceleration. Due to these issues it turned out to be easier (in the long run) to make a spreadsheet calculator to do the same thing.
It was very helpful and it helped me with my homework I suggest that you get this app I tried many other apps but this one is by far the best
