Callyzer - Analysis Call Data for Android

App overview

Callyzer is a no-cost Android app that replaces your phone’s default dialer to give you detailed insights into your calling activity. It collects call records and presents them in both visual and tabular formats so you can review patterns and trends over time.

What it does

• Export call logs into CSV files for further analysis on a PC or spreadsheet app.
• Visualize calling history with charts and tables to spot trends quickly.
• Act as the system’s primary phone handler so incoming and outgoing calls are tracked automatically.
• Provide advanced filters and comparison tools to zero in on specific time ranges or durations.

How to get started

1. Install Callyzer from the Play Store and grant the permissions it requests for call and storage access.
2. Set it as your default phone app when prompted so it can intercept and log calls.
3. Open the app to view your recent calls displayed in both lists and graphical summaries.
4. Apply filters (by date, contact, type, or duration) to narrow the view to the records you need.

Tips for analysis

• Use the CSV export to run custom queries or create pivot tables if you need deeper statistical breakdowns.
• Compare call durations across different periods to understand changes in usage or activity.
• Combine the table and graph views to validate trends visually and check raw numbers when needed.
