PassMark AppTimer is a lightweight, free Windows utility designed to benchmark the startup time of any executable application. It repeatedly launches a specified program, measures the time taken for the application to become ready for user input, and logs these results for analysis. The tool automates both the launching and closing of applications, ensuring consistent and repeatable timing measurements. AppTimer is portable, requires no installation, and outputs results in a log file for further review or comparison.

Key Features

Automated Application Launch and Measurement Automatically runs a selected executable multiple times and measures the time until user input is accepted.

• Ensures consistent, repeatable timing results
• Suitable for benchmarking application startup performance

Automated Application Closure Closes the tested application after each run in an automated fashion.

• Reduces manual intervention
• Supports batch testing scenarios

Detailed Logging and Export Logs each run’s startup time and other relevant data to a file.

• Provides average, minimum, and maximum launch times
• Results can be saved in CSV format for further analysis

Customizable Test Runs Allows users to specify the number of test iterations and window detection methods.

• Adapts to different application behaviors
• Enables more robust benchmarking

Portable and Lightweight No installation required; simply unzip and run.

• Easy to deploy on multiple systems
• Suitable for use from USB drives
