What Dynano does
Dynano sits at your notch as a small pill. Hover it to expand into full pages of system, productivity and developer plugins. Pick the peeks that matter, rearrange the pages, and let Dynano surface the right info at the right time.
Claude usage at a glance
Track your Claude sessions without leaving your editor. Dynano reads your local usage file and surfaces session %, weekly quota and current model spend.
- 5-hour session progress and remaining time
- Weekly quota with reset countdown
- Active model and approximate cost
Animated desk pets
Pixel-art companions live in the notch. They idle, walk, run and react — a tiny bit of joy on every screen.
- Animated pets including snakes and dragons
- Idle, walk, run, swipe and reaction states
- Pick a default or rotate through favourites
Pick the peeks that matter
Choose the default left and right peek. Pick from RAM, CPU, Battery, Media, Calendar, Reminders, Claude usage, Sessions and more.
- Drag-and-drop slot configuration
- Independent left and right defaults
- Mix system info with productivity data
Attention-aware
Peeks can request your attention when something changes. Dynano promotes them to the front and can switch the expanded page automatically so the right info is always one glance away.
- Active Claude session in progress
- Upcoming calendar event or overdue reminder
- High CPU or RAM usage
- Per-peek priority list with optional auto-switch to the expanded page
Expandable plugin pages
Hover the notch and Dynano expands into full pages: Compute, Claude, Calendar, Reminders, Git and Media. Reorder them with drag and drop and scroll-cycle between them.
- Compute, Claude, Calendar, Reminders, Git, Media
- Drag-drop ordering of the page rotation
- Scroll-wheel page cycling with haptic feedback

Frequently asked questions
Is Dynano free?
Yes. Dynano is free to download. The DMG is signed with an Apple Developer ID and notarized by Apple.
Which Macs are supported?
Dynano targets macOS 26.2 and later and runs natively on both Apple Silicon and Intel Macs.
Does it work on Macs without a notch?
Yes. On Macs without a notch, Dynano renders as a floating pill near the top of the screen and behaves the same way.
Does Dynano send my data anywhere?
No. All system metrics, Claude usage stats, calendar events and reminders are read locally and never leave your Mac.
Why does Dynano need Calendar and Reminders permissions?
Those permissions are only used to render today's events and overdue reminders inside the corresponding peeks and pages. Permissions are optional — peeks you don't enable never request access.
How do I uninstall Dynano?
Quit the app from its menu, then drag Dynano from /Applications to the Trash. Settings are stored in your user defaults and can be removed with `defaults delete com.matthiasschedel.Dynano`.
