About this app

Fill RAM and see how Android responds to memory pressure. With FillRam's RAM stress test, you choose a target, increase the load gradually, and watch RAM and swap usage in real time. No root required.

Fill RAM to a target
In Fill mode, set a target percentage for physical RAM usage and choose a Light, Balanced, or Aggressive profile. Watch available RAM, memory allocated by FillRam, swap usage, and low-memory status as the load increases.

Run a memory pressure test
See how much memory FillRam can allocate on your device and how Android responds under load.

Memory benchmark
You can also check your device's memory speed. Clear explanations and a built-in guide help you understand the results.

Included without a subscription
• Manual RAM filling with a target and load profiles
• Live RAM and swap readings
• Calibration and the memory pressure test
• Summaries of your latest runs
• Memory speed benchmark
• Result explanations and a built-in guide
