RAM Guard is a clean, honest tool for keeping an eye on your iPhone's memory. No exaggerated claims — just a clear picture of what's really happening on your device. ■ Real-time memory dashboard Visualize total / used / available memory with an easy-to-read donut chart. Colors shift with usage (normal, caution, warning) so you can read the state at a glance. ■ Free up memory Safely attempt to reclaim memory with a single tap, and see a clear before-and-after comparison of your available memory. ■ Device info Model, iOS version, total RAM, storage, and battery status — all the key details about your device on one screen. ■ Cleanup guide Practical, step-by-step tips for freeing up space: reviewing photos, checking storage-heavy apps, and managing background apps. ■ Built to be honest For security reasons, iOS does not allow one app to force-quit or wipe another app's memory. RAM Guard is upfront about this — it never overstates results and simply shows you the changes in your memory status transparently. A clean design with no clutter. Stay on top of your device's memory with RAM Guard.
