Every release, newest first.

What changed in each version of NotchiDex, in plain words. Updates arrive through the Microsoft Store by themselves, usually within a day or two of a release going live.

1. 0.2.0

   Live now22 October 2026

   The Pro version. The app stays free; Pro is a one-time unlock.

   • Dock the island at the left or right end of the screen at any height. It tucks away to a small cat-sized pill and comes out when you hover or when Notchi goes exploring.
   • More tries and shorter waits when you feed Notchi or throw the ball.
   • Island size, solid or translucent background and opacity.
   • The file shelf, the water, break and eye-rest reminders, and Notchi's fur colours, hats and taskbar roaming move into Pro. Founders keep all of it.
   • New in Pro: three more pets (Coco the hamster, Mochi the golden retriever and Piku the parrot), more expressions, and a System tile with memory, processor and the apps using the most RAM.
   • Every PC can try Pro free for 7 days from Settings. It starts only when you press the button.

   The app stays free, with a one-time Pro unlock ($4.99, no subscription). Everyone who installed before Pro launched is a Founder and has Pro free. How Pro works →

2. 0.1.3

   Earlier19 October 2026

   Free for everyone. NotchiDex can now tell you when a new version is out.

   • A small card on the island says when a new version is ready, with Update now and Later. Later asks again the next day.
   • Choose how updates work in Settings > Updates: Ask me (the default), Auto, which installs by itself, or Manual, which never checks.
   • Nothing pops up during fullscreen games and videos.
   • After an update, Notchi tells you which version you are on.

   The check asks the Microsoft Store, not us, and Manual turns it off. What exactly is sent →

3. 0.1.2

   Earlier15 October 2026

   Free for everyone. A livelier Notchi, and a few fixes. The Microsoft Store installs it by itself, or update from your Library.

   • Feed Notchi a pixel fish. It drops onto Notchi's mouth in a random colour and gets eaten in three bites.
   • Throw Notchi a ball. Each throw uses a random colour.
   • Notchi says when it is full and how long until you can feed it again. Keep feeding and it gets stuffed and turns down food and play for a few minutes.
   • Pet Notchi too fast and it asks for space, then pauses petting for a few seconds.
   • Levelling takes real time now. Notchi has something to say at levels 100, 250, 500, 1000 and 2000.
   • Notchi's age and weight grow with the days and the meals. Both show in Settings > Cat.
   • Set a custom timer from 1 minute to 3 hours with the new − and + buttons.
   • The battery icon fills to the charge level, in green, amber, then red as it drops.
   • Fixed: the island now closes by itself when you open it from the tray.
   • Fixed: Notchi no longer sticks to the pointer after you pull it out of the island.
   • Fixed: the battery view no longer clips the Power settings button, and the Home tile says "Charged" instead of a cut-off "Fully charg...".

4. 0.1.1

   Earlier10 October 2026

   A new look, and a fix for a real annoyance.

   • New logo: the island with Notchi inside. It is the app icon, the tray icon and the Store tile.
   • Fixed: the island no longer covers the minimise, maximise and close buttons of other windows. It steps aside until you move the window or switch to another.

5. 0.1.0

   First beta7 October 2026

   The first public release, on the Microsoft Store.

   • A small island at the top of the screen that expands when you click or hover.
   • Now playing from any app, with album art, play and pause, skip and a seek bar.
   • Volume bar (scroll over the island to change the volume) and a battery card when you plug in or run low.
   • Focus timer you start from the island.
   • File shelf: drop files on the island, drag them out later.
   • Water, break and eye-rest reminders, quiet in fullscreen.
   • Notchi the pixel cat: naps, reacts to music and timers, wanders along the taskbar, can be petted, fed and played with. Level up for fur colours and hats.
   • Hides during fullscreen games and videos. No account, no telemetry, no network requests.
