Menu bar
Always on screen.
The numbers you actually watch, right there in the bar — no window to open, no clicking around. Every chip is optional and reorderable, so you can build a single CPU number or a full row.
Click for the detail.
One compact popover with every metric, its own chart, and the top five processes by CPU or memory — without leaving what you were doing.
- Choose which metrics appear and drag them into the order you want
- Two-line labels, so you never have to guess which number is which
- Compact spacing to fit more into a crowded bar
- The menu bar gets its own theme, independent of the app window
Reorder, relabel, compact.
Settings shows you the bar as you build it. Pick a display style — numbers only, graph only, graph with value, or minimal — set the order, and watch the preview update.
Dashboard
Not just a number
that goes up and down.
The breakdown behind it. Dedicated detail pages for CPU, GPU, Memory, Storage, Network, Battery and Sensors, each with a large live chart and the numbers that matter.
CPU
Live load with a stacked user / system chart, per-core bars split into Performance and Efficiency cores, and 1 / 5 / 15-minute load averages.
GPU
Utilisation and die temperature, with the same one-second history as everything else.
Memory
Used against total, plus the App / Wired / Compressed / Free breakdown behind the number.
Storage
Capacity per volume, live read and write throughput, and how much has been read and written since boot.
Network
Download and upload on opposite sides of the axis, so a busy upload never hides a busy download.
Battery
Charge, health, cycle count and live power draw in watts.
Plus Top Processes, sortable by CPU or memory, on the dashboard and on its own page.
Appearance
A look that fits your desktop.
Multi-colour (a semantic colour per metric), Dual, Mono Amber, Mono Gray, Mono Blue and a clean Light theme. The Mono Gray menu bar adapts to your wallpaper exactly like macOS's own menu bar items.
Sensors
Temperatures and fan speed.
macOS doesn't expose thermal sensors or fan speed to sandboxed App Store apps. Sharp Lynx reads them through the free Sharp Lynx Helper, a small companion you download from this page.
The app will prompt you, and can start, stop and update the Helper for you. Everything else works without it.
Privacy
Private by design.
No account. No tracking. No analytics. No network requests. Every number is measured on your Mac and stays on your Mac.

Sharp Lynx Helper
macOS does not let sandboxed App Store apps read thermal sensors or fan RPM. Sharp Lynx Helper is a small, separate app — Developer ID signed and notarised by Apple — that reads those two things and hands them to Sharp Lynx.
You only need the Helper if you want temperatures and fan speed. CPU, GPU, memory, disk, network and battery all work without it.
How to install
- Click Download Sharp Lynx Helper above to get
SharpLynxHelper.dmg. - Open the downloaded
.dmgfile. - Drag Sharp Lynx Helper into your Applications folder.
- Launch Sharp Lynx — it will detect the Helper and start it for you. Temperatures and fan speed appear on the Sensors page.
Sharp Lynx can also start, stop and update the Helper from its settings, so you normally won't need to touch it again.
Previous versions
Use the latest Helper unless you are running an older Sharp Lynx that needs a specific one.
- Version 1.0 — 2026-07-22 First release. For Sharp Lynx 6.0 and later.
