When you need the space back, release it in one tap. HOW IT WORKS • Reserve — Set aside real disk space as your personal buffer • Release — Return reserved space to your device anytime • Visual dashboard — See Available, Reserved, and Used at a glance FREE FOREVER • Reserve up to 1 GB at no cost • Release is always free — no paywall on release PREMIUM (ONE-TIME PURCHASE) • Unlimited reserve capacity • No subscription · No ads • Restore Purchase supported on all your devices Built for people who want a simple buffer before big downloads, shoots, or cache spikes—not another “clean my phone” app. Requires iOS and macOS with available local storage. Reserved space uses real disk allocation on your device.
