InterCalc vs Interp Calculator
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.

Interpolation Calculator is a utility tool for performing linear and bilinear interpolation based on entered numerical values. The app is designed for students, engineers, technicians, and anyone working with tabular data or numerical analysis. Functions available: Linear Interpolation: - Calculates the intermediate value between two known data points. Bilinear Interpolation: - Computes a value based on four surrounding points in a two-dimensional grid. Features: - Works entirely offline – no internet connection is needed. - Includes both light and dark themes for comfortable use in different environments. - Minimal and user-friendly interface focused on functionality. - Suitable for technical fields such as mathematics, engineering, physics, and data analysis. The application is designed to be simple, efficient, and accurate for quick interpolation tasks on the go or in professional environments

Verdict
The clearest difference is price: InterCalc at Free against Interp Calculator's $0.99. Interp Calculator's advantage is iOS requirement (14.0 vs 18.6). On ads, in-app purchases and device support there is nothing between them.
