FillRam: RAM Stress Test

FillRam is a lightweight Android utility for developers, testers, and power users who want to observe how a device behaves under memory pressure.

Choose a target pressure level, start the fill process, and watch live memory information as the device approaches low-memory conditions. FillRam is designed for testing and learning, helping you reproduce memory-pressure scenarios in a simple and controlled way.

What you can do with FillRam:

• Simulate controlled RAM pressure up to a selected target

• Switch between Light, Balanced, and Aggressive pressure profiles

• Monitor free memory, app memory, total memory, and low-memory status live

• Reproduce low-memory conditions to evaluate app and device behavior

Important:

• When available RAM becomes critically low, Android may stop the app. This is normal and expected during this type of test.

• FillRam does not clean RAM, speed up your phone, or improve performance. Its purpose is to help you test and understand memory behavior.

If you need a straightforward way to trigger and observe memory pressure on Android, FillRam gives you a fast and focused testing tool without unnecessary complexity.
