InterCalc vs XL Random
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
InterCalc
This app performs linear interpolation using a set of X-Y values to define a relationship. It can calculate values based on defined points, useful for tasks like converting pressure readings to fluid volumes in containers or performing simple unit conversions.
- Linear interpolation of X-Y values
- Defines arbitrary functions from data points
- Calculates fluid volume from pressure readings
- Performs unit conversions (e.g., temperature, speed)
- Supports custom data sets

This application is designed to linearly interpolate a value given a set of X-Y values that define a relationship. The X-Y values can be as simple as two points that specify a simple line, or they can be a set of points that specifies an arbitrary function. One use of this program is to calculate the amount of fluid in a container given a pressure reading at the bottom of the tank. Typically this situation results in several pressure readings and corresponding volume ( gallons, liters ) readings as the tank is being filled. Once the pressure measuring device is so calibrated, pressure readings can then be converted to gallon or liter values. Other uses include simple conversions between Fahrenheit and Celsius, or between kph and mph.

Verdict
The clearest difference is in-app purchases: InterCalc at none against XL Random's 1. InterCalc also leads on ads (none vs shown). XL Random's advantage is update cadence (every 4 months vs every 11 months) and iOS requirement (15.6 vs 18.6). On price, rating, ratings volume and device support there is nothing between them.
