What we built
The Mac app, the brand and the website
A MacBook on a block of graphite stone in a dark studio, a sky-blue neon line rising into one peak behind it. On screen, over a deep-blue ribbon wallpaper, iSurge has opened from the notch: memory, battery and CPU, Music playing in the sound card, and the apps using the most.iSurge, opened from the notch

A thousand processes, a few apps

Activity Monitor lists every process, about a thousand on a normal day, and leaves you to work out which belongs to which app. iSurge adds the helpers up into their apps: here 1,047 processes become 8 apps, and Google Chrome’s 39 are one row.

Activity Monitor and iSurge side by side. Activity Monitor scrolls through 96 of 1,047 processes: ChatGPT Networking, Google Chrome Helper (Renderer) three times, Safari Web Content, clang. iSurge shows 8 apps, one row each: Google Chrome with 39 processes, Xcode with 9, Discord, Safari, Spotify, ChatGPT, Mail and Messages.

Your Mac’s pulse, at the notch

Two live numbers sit either side of the notch, and whatever’s playing shows on the right. Rest the pointer on it and it opens; swipe for GPU, disk, network and temperature.

Quiet, until it matters

Most of the day iSurge is two small numbers. It speaks up when an app keeps eating memory, and it hands you a volume for every app the moment something starts playing.

Sound

Control the sound of every app

Turn the music down without touching the call. Each app gets its own volume, and its own speakers or headphones.

A line that surges once

One mark, a line that runs flat and rises once, the way a busy moment looks on a graph. And a colour for every stat, the same in the notch, the menu bar, the window and the site.
