## What is Curve Fit Graph Calc Lite?

iCurve Fitter & iMulti Fitter, are of the best graph applications available in the App Store, yet easy to use. they are handy tools essential for doctors, engineers, students and laboratories. Used to derive the mathematical equation that fits a set or multiple sets of experimental data points, at any required degree. it uses advanced polynomial Interpolation method to plot those data points and draw the derived equation’s curve. Just enter your experimental readings in pairs of (x, y), and the app will do the rest for you, and represents the graphical output instantly on a Cartesian plane. You can always manipulate the graph interactively (zooming in/out, scrolling and tracking). so you can determine the value of (y) for any given value of (x), plus the slope of the curve at that specific point. also you can get the precise numbers using a dedicated Solver UI. and now you can calculate & visualize area under curve for a given interval. you always can get the derived equations and numerical results in a formatted sheet that can be exported or shared. Minima, maxima & root points are also calculated and represented automatically.

► Features: 
- Easy Data Points entry form.
- Specialized numeric & function keyboards.
- Controlling graph look & behavior.

### 1/5 — No good

*2023-02-05*

Added my data then app crashed wiped it deleted straight away

### 1/5 — Not worth much

*2021-08-18*

Poor solutions.  A good curve fitter examined all the options within limits of terms. You would have to know the correct equation format here and it would have to be within the limits of the app.

### 5/5 — Working perfectly

*2016-03-28*

Useful app, it works perfectly well. I used it and it convinced me to buy the paid version. I strongly recommend it.

### 1/5 — Crash crash

*2016-01-27*

On IOS9, The app crashes immediately. I can't even get into the app to try and review it.

**Developer response:** It was update because of system version. Please check again, it's better now! Many Thanks.

### 1/5 — It does not work

*2015-12-25*

It could not be opened.

**Developer response:** It was update because of system version. Please check again, it's better now! Many Thanks.

### 3/5 — A Must For Students

*2014-09-30*

A very useful tool that has great potential. The full version is even a more powerful application. 
This app makes it so easy to see a graphical representation of a set of data points in a simple and straight forward manner. 
Why 3 stars?! I believe that this app leaves much to be desired by high school and college students.
