Step into a living, ambient environment while you work: rain on the window, embers in the dark, moonlight over still water, and let everything else fade.
Cave is a focus timer built around one idea: your session should feel like somewhere, not just a countdown. Choose from 11 animated environments, each with its own light, weather, and mood, then run a distraction-free focus session inside it.
CHOOSE YOUR SPACE
11 living environments: Mountain Cave, Rain, Forest Morning, Snow Cabin, Campfire, Autumn, Spring, Night Sky, Zen Garden, Day/Night (which follows the real sky as your day goes on), and a battery-saving Minimal theme. Each one is animated in real time, not a static image.
FOCUS ON YOUR TERMS
Start with a built-in preset (25·5, 50·10, 90·20, and more) or set your own custom focus and break length. Auto-continue rolls you straight from focus into break and back, with no taps required. A soft chime marks the end of each phase, not a jarring alarm.
SEAL THE CAVE: BLOCK DISTRACTIONS
Turn on Focus Shield and distracting apps stay blocked for the length of your session. Focus Shield uses Android's Accessibility Service, with your explicit permission, to detect which app is currently in the foreground. That's the only thing it checks: Cave never reads your screen content, logs what you type, or sends anything off your device.
BUILD YOUR STREAK
A daily focus goal, a running streak, a week-at-a-glance chart, and full session history, so the work you put in is never invisible.
YOUR DATA STAYS YOURS
No account. No login. No cloud sync. Everything lives on your device, and one button in Settings permanently erases all of it, any time you choose. Export your session history as a backup file whenever you like: it's yours, and Cave never uploads it anywhere.
Free to download. No ads.
A calmer way to sit with a timer, whether it's 25 minutes or three hours.
A living, ambient focus timer with app blocking to keep distractions out.
