I love my Logitech mouse.

But honestly, I just wanted to see its battery percentage in my menu bar.

I didn't want heavy background processes constantly running just to give me a single number.

So, I built lsom.

It's a tiny, native SwiftUI app designed exclusively for your Mac.

There is no background daemon draining your CPU. It just talks directly to your USB receiver using HID++ 2.0 protocol.

Out of the box, lsom is completely free.

It automatically detects your device, places a neat battery indicator in your menu bar, and politely notifies you when power is running low.

Simple, quiet, and exactly what it needs to be.

If you need to tweak how your mouse behaves, I made a Pro version.

It lets you control your DPI, change the polling rate, and remap your buttons to fit your workflow.

No subscriptions. Just a simple, one-time $14.99 to unlock it forever.

lsom is currently in beta. If a fast, lightweight mouse utility sounds nice to you, I'd love for you to give it a try.

Pro upgrade available directly inside the app.
