A space designed
for focus
Step into a living, ambient environment while you work. Rain on the window, embers in the dark, moonlight over still water — pick a scene, start the timer, and let everything else fade.
Three steps into deep work
Choose your environment
Eleven living scenes — rain, forest, campfire, night sky, and more — each with its own light, weather, and sound of a session ending. Pick whatever matches your mood.
Set your session
Start with a preset — 25·5, 50·10, 90·20 — or set your own focus and break length. Auto-continue rolls you straight from focus into your break and back, no taps required.
Seal the cave, and focus
Turn on Focus Shield and distracting apps stay blocked for the whole session. One ring, one timer, nothing else — until it's time for a real break.
Every mood has a place
Eleven ambient scenes, each animated in real time in the app. Tap one — this page will borrow its colors, the same way Cave itself changes around you.
Everything built to protect one thing
Your attention.
Focus Shield
Block distracting apps for the length of your session. Cave only checks which app is in the foreground — it never reads your screen, and that check never leaves your device.
Sessions that fit you
Five built-in presets from a quick 25 minutes to a 3-hour deep-work block, plus a fully custom focus and break length. Auto-continue rolls you straight from one into the next.
Streaks & progress
A daily goal, a running streak, a week-at-a-glance chart, and full session history — so the work you put in is never invisible.
A quiet chime
A soft cue when a focus block or break ends — no jarring alarms, no notification spam. Turn it off entirely if you'd rather sit with the silence.
Backup & restore
Export your entire session history as a .zip whenever you like, and bring it with you to a new device. The file is yours — Cave never uploads it anywhere.
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.
A place your brain
learns to recognize
Most focus apps give you a bare countdown and hope willpower does the rest. Cave gives your session a place instead — a scene with weather and light that changes with the time of day, so sitting down to work starts to feel like walking into a room built for exactly that.
Choosing a theme becomes a small ritual before you start. Running distractions into a wall — Focus Shield — removes the easiest way out. And a visible streak turns one good session into a habit you can actually see building, day over day.
None of it requires an account, a subscription, or your data leaving your device. It's just a calmer way to sit with a timer for 25 minutes — or three hours.
