Analyze your chemical molecules from a topological perspective with the “Chemical Graph Index Calculator”. The application works in two different ways:

Manual Calculator

Enter the number of nodes and manually create the adjacency matrix.

Support parametric calculations such as general Randić or General Sum indices by entering an optional “alpha” value.

Graph Reader

Select a graph image from your phone gallery.

Start calculating by redirecting the calculated matrix to the Topological Indexes screen, with the alpha value if necessary.

Supported Topological Indexes:

Wiener Index and Hyper Wiener

Randić Connectivity and General Randić Connectivity

General Sum Connectivity

Atom Bond Connectivity

Zagreb Series (First/Second Zagreb, Eccentricity variants)

Eccentric Connectivity and Modified Eccentric Connectivity

Total and Average Eccentricity

Geometric–Arithmetic Index

Features

✔️ Manual input and image-based matrix extraction

✔️ Alpha value support for parametric calculations

✔️ Modern, dark theme-oriented interface

✔️ Single-click result display and sharing

How to Get Started

On the home screen, select “Manual Calculator” or “Graph Reader”.

If you chose manual mode, enter the number of nodes and matrix values.

If you are in image mode, select a photo from the gallery and tap “Calculate Matrix”.

On the Topological Indexes screen that opens, select the index you want and press “Calculate”.
