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”.
