Quiet until it isn't.
Most of the time the island is a small dark pill with Notchi in it. It grows a little when you hover, opens Home when you click, and never steals keyboard focus from what you're doing.
Free beta · Windows 10 & 11
A tiny island for your desktop, and a cat who lives there.
NotchiDex sits quietly at the top of Windows: what's playing, the volume, your timer, a shelf for files and a nudge to drink water. Made by one person, for people who like their computer a little kinder.
Free forever for the first 100 users. No account, no ads, nothing leaves your PC.

Live demo · runs in your browser
Go on, poke the island.
This is the real island on a pretend Windows desktop. Hover it, click it, scroll over it for volume, pet the cat, or drag a desktop icon onto it.
The demo is a whole Windows desktop, so it's tiny on a phone. It's much nicer on a computer.
A lit button means that thing is happening on the demo desktop right now. In the real app the island sits above your actual windows, never takes keyboard focus, and hides in fullscreen games and videos.
What it does
One small island. A handful of jobs, done quietly.
It stays a 128-pixel pill until something is worth showing, then grows just enough and gets out of the way again.
just a little pill
See what's playing, from any app.
Spotify, a YouTube tab, most modern players: anything that reports to Windows media controls shows up with its album art and a little visualizer. Click for play, pause, skip and a seek bar.
Scroll over it to change the volume.
Hover the island and scroll, in any view. A slim bar shows the level, then the island goes back to what it was showing.
A timer you can actually see.
Start 5, 15, 25 or 50 minutes from Home. The ring stays visible while you work. If music is playing too, it moves to a small bubble beside the island.
Park files for a minute.
Drag files onto the island to keep them handy, then drag them back out into an email, a chat or another folder. Nothing is copied or uploaded: the shelf only remembers where the files are.
Water, breaks and eye rest. Kindly.
One quiet card at a time, never a pile of notifications. You set the intervals, a daily water goal and active hours, and it stays silent while you're in a fullscreen app.
Everything in one click.
Click the island for Home: the time, your water count, battery, the shelf, the timer, and Notchi, who you can pet, feed and play with.
It knows when to disappear.
Start a game, a movie or a presentation in fullscreen and the island slides away, with Notchi tucked in behind it. Nothing pops up until you leave fullscreen. Maximized windows don't count: the island stays on top of those, where it's useful.

Meet Notchi
An original pixel cat with opinions, mostly about water.
Pet, feed and play with Notchi to grow your friendship. Levels unlock fur colours and hats. It's just for fun, and nothing is ever locked behind a payment.
Fur Cream
Hat No hat
- naps when you're away, wakes up when you're back
- reacts to music, timers, plugging in and low battery
- goes for walks on the taskbar. pick it up, drop it anywhere
- has an off switch (and a calmer personality setting)
Privacy
Things it does (and things it won't).
NotchiDex makes no network requests, has no account and sends no analytics. What it reads to do its job never leaves your PC.
✓ shows what's playing + play / pause
✓ scroll to change the volume
✓ a focus timer you can actually see
✓ a shelf for files, water + break reminders
✗ track you, need an account, show ads
✗ read your clipboard, screen or keystrokes
✗ talk to the internet at all
Never in the way
No keyboard focus stolen, clicks pass through the empty space around it, and it hides in fullscreen.
Light on your PC
A native Windows app, not a browser in disguise. It waits for Windows events instead of polling, so idle CPU is effectively zero.
Local by default
Settings, files and media info stay on your computer. There's no cloud to sign in to.
Small on purpose
A few things done well. New features come from what people actually ask for on the feedback page.

Questions
Good questions, honest answers.
Which versions of Windows does it run on?
Windows 11, and Windows 10 version 2004 or newer, on 64-bit (x64) PCs. It installs from the Microsoft Store like any other app.
Will it slow my PC down?
It's a native Windows app that reacts to Windows events instead of checking things in a loop, so it uses effectively no CPU while idle. Measured idle, it shows about 11 MB in Task Manager and 0% CPU. It uses more while you have Home or the shelf open, and gives that memory back once it has been idle for about 45 seconds. Details and a script to check your own PC are on the footprint page.
Which music apps work?
Anything that reports to Windows media controls, the same thing that powers the media panel in Windows: Spotify, browsers playing YouTube or other sites, and most modern players.
What happens in fullscreen?
When a game, movie or presentation fills the screen, the island and Notchi hide and reminders wait. As soon as you leave fullscreen, the island comes back. A normal maximized window doesn't count as fullscreen.
Does it work with more than one monitor?
The island lives on your main display for now. Choosing the display, or following your mouse, is on the list.
Can I turn the cat off?
Yes. You can hide Notchi, make it react less often, pick a calmer personality or stop it from roaming. You can also pause it for 30 minutes from the right-click menu.
What does "free for the first 100 users" mean exactly?
NotchiDex is free during the beta. When paid licences start, the first 100 people who installed it keep it free forever. Everyone after that pays $5 once for a lifetime licence.
How do I uninstall it?
Right-click NotchiDex in the Start menu and choose Uninstall, or remove it from Settings › Apps. Nothing is left running.
