iSurge puts an activity monitor, per-app volume, disk cleanup, and developer tools at your Mac's notch. This beginner's guide covers setup, the notch stats, volume mixing, disk cleanup, dev tools, and pricing.
Learning how to use iSurge starts with knowing which app you are looking at. iSurge is the Mac notch utility built by Ruthran that launched on Product Hunt on October 28, 2026 — it puts a live activity monitor, per-app volume, disk cleanup, and developer tools at the notch of your MacBook. It is not Surge.sh (the static-site hosting service), not Surge 5 (the network proxy tool), not the Surge XT synthesizer, and not the ISURGE iron tablets sold by pharmacies. Those name collisions will keep showing up in search results, so this tutorial covers the Mac app only: what it does, how to set it up, and how each of its five lanes works. iSurge requires an Apple silicon Mac (M1 or later) running macOS 15 Sequoia or newer; the notch features need a MacBook with a notch. If your work lives in containers, iSurge groups them by project — the Docker beginner guide covers the container side of that picture.
What Is iSurge, Exactly?
iSurge is a one-time-purchase Mac menu-bar app that replaces four separate habits: checking Activity Monitor when the Mac slows down, fiddling with system volume sliders, running a disk cleaner, and typing commands to see who is sitting on a port. It shows two live stats beside the notch at all times, and when you rest the pointer there, it opens a panel with your whole Mac. The maker's own summary: an activity monitor at the notch, each app's sound your way with mic control, disk space made room for without guesswork, developer tools for projects, ports, and Homebrew, plus a focus timer and Keep Awake. There is no account, no analytics SDK, and no login — the app sells a license key you paste in.
iSurge is sold by its maker through isurgemac.com (support: [email protected]). It is a native Mac app that keeps everything on your machine — stats, history, and settings never leave your Mac, it goes online only for updates, license checks, and extras like song covers and weather, and sound is never recorded (it only passes through to set each app's volume).
How Do You Set Up iSurge for the First Time?
There is no trial flow or account to create — you buy a license, download the app, and paste the key. Here is the whole first run, in order:
- Buy the license at isurgemac.com. Pick Lifetime or the one-year tier, then pay. Nothing renews by itself.
- Find your key. It is on the page you see right after paying, and in your purchase email. If no email arrives after a few minutes, check spam, then write to [email protected].
- Download the app from isurgemac.com/download and move it to your Applications folder.
- Open iSurge and paste the key. The app activates with no sign-up and no login.
- Grant the permissions it asks for. Keep Awake's lid-closed mode uses a small privileged helper that you must explicitly allow; without it, that one feature cannot work.
After activation, iSurge sits in the menu bar and places its two live stats beside the notch. Hover there to open the full panel. The app checks for new versions once a day and asks before installing; you can also check manually in Settings > About or turn automatic checks off. If you owned iSurge before version 0.4, it stays free for you — no new purchase needed.
What Shows Up at the Notch?
The notch moment is iSurge's signature: two live statistics sit beside the notch, always visible, and resting your pointer there opens a panel with your whole Mac. The maker's origin story is that his Mac slowed down, he opened Activity Monitor and scrolled through about a thousand processes, and the notch — the spot he looked at all day — did nothing. So iSurge put the answer there.
What "the answer" looks like: a thousand processes added up into the apps you know. macOS reports processes, not apps, so iSurge looks at where each process came from on disk, finds the app on that path, and files the process there. Beta and release copies of the same app merge into one row, Xcode tools become "Developer Tools," and macOS components collapse into one "macOS System" row. A Mac that has been on for a day has roughly a thousand processes — the maker's blog shows a screenshot with 1,047. Clicking any app's row shows what it uses now, what it usually uses, and its past warnings; when the Mac is under strain, the warning names the apps behind it. If something is slowing you down, you can quit it right from the row — one click, no window hunting.
How Is iSurge Different from Activity Monitor?
iSurge reads the same macOS data as Activity Monitor, but it presents it like a normal person would want to read it. The clearest difference is CPU percentages: macOS counts each core, so an app maxing out one core of a 10-core Mac reads 218.7% in Activity Monitor. iSurge divides by the number of cores instead, so the same app shows 21.9% — a bit over a fifth of the whole machine. Fifty percent is half your Mac; 100% is all of it. (The old per-core figure is still one hover away on each app's CPU row, and the CPU page shows both.)
| Behavior | Activity Monitor | iSurge |
|---|---|---|
| CPU percentages | Per-core (can exceed 100% many times over) | Normalized to the whole machine |
| Process list | Thousands of raw processes and helpers | Grouped into the apps they belong to |
| Ordering | By the column you click | By CPU-plus-memory total, so idle memory hogs stay visible |
| System parts | Listed like everything else | macOS interface parts excluded (you cannot quit them); most system usage counts only what macOS reveals |
| Always visible | Only when you open the window | Two live stats beside the notch; full panel on hover |
| Strain warnings | None | Names the apps behind the strain, with each app's usual and past warnings |
| Quitting an app | Find the row, then quit | Quit button right on the row |
One honest limit, stated by the maker: macOS does not reveal per-process usage for most system processes, so the "macOS System" row counts what macOS is willing to share. Since version 0.4, Keep Awake runs a small helper of its own — only to keep the Mac awake with the lid closed, and only once you allow it; it does not read your processes.
How Does Per-App Volume Work on a Mac?
macOS gives you one system volume; iSurge gives every app its own volume and its own output speakers. The music goes down and the video call does not, because each app has its own slider. You can also see which app is currently using your microphone, and one shortcut mutes them all: Option-Command-M (⌥⌘M).
This is the lane that makes "mac per app volume" searches land here. Per-app routing is genuinely hard to find natively on macOS — the Sound section is iSurge's answer to "hear what's playing, right at the notch." The maker adds that sound is never recorded: audio only passes through the app so each app's volume can be set. If you care about privacy, that is the line to remember — a volume mixer that records audio would be a spy tool; iSurge says it does not do that.
What Does iSurge's Disk Cleanup Actually Delete?
iSurge shows what fills your disk, clears what is safe, and asks before it moves anything. The maker's safe list is caches, old installers, and downloads — the three categories where a wrong guess costs you nothing and a right guess wins gigabytes. Removing an app also takes the files it leaves behind, which is the part most uninstallers skip: dragging an app to the trash leaves preferences, caches, and support files scattered on the disk, and iSurge removes those leftovers too.
The "asks before it moves anything" rule matters. Aggressive cleaners that delete first and explain later are how people lose important files; iSurge's model is the opposite — show what fills the disk, propose what is safe, and get your approval before moving. For beginners, the safe first run is: look at the disk breakdown, clear caches and old installers, and use the downloads pass only after checking what is in there.
What Do iSurge's Developer Tools Do?
The Developers section is "your projects, ports and Homebrew, in one place." Four things live there: each project with what it runs and what it costs your Mac, a port view that shows who is on a port (and frees it in one click), containers grouped by project, and Homebrew.
The port view is the daily time-saver — the classic "address already in use" moment, resolved without a terminal command. The per-project cost view is the interesting one for performance work: you can see what a project's stack actually costs your Mac while it runs, which turns vague "the dev environment is slow" complaints into numbers. If you manage packages with Homebrew, iSurge surfaces it here; the Homebrew beginner guide covers the package manager itself. And since iSurge groups containers by project, the Docker container guide is worth reading if you want to understand the workloads you are watching.
What Are the Focus Timer and Keep Awake?
The focus timer sits beside the notch and runs work in rounds, pausing when you step away — so a break does not silently eat your round. Keep Awake keeps the Mac from falling asleep in the middle of a download, and since version 0.4 it can keep the Mac awake with the lid closed, using the small privileged helper you allowed at setup. That lid-closed mode is the one feature that needs the extra permission; everything else works with standard permissions.
Keep Awake is for local jobs that must finish — downloads, renders, long builds. For terminal work on remote machines, the same idea lives in the tmux beginner guide: tmux keeps the session alive server-side even if your connection drops, which is the remote counterpart to keeping your own Mac awake.
How Much Does iSurge Cost?
iSurge is a paid app with no subscription and no free tier: a lifetime license or a one-year license, both as launch prices in November 2026. Here is the current pricing, verified on isurgemac.com today:
| Tier | Launch price | Regular price | What you get |
|---|---|---|---|
| iSurge Lifetime | $14.99 once | $29.99 | All of iSurge: live stats, Sound, Mic, Disk, Dev, Focus, Keep Awake; every update included for life; transferable — deactivate on the old Mac, activate on the new one; 14-day money-back |
| iSurge, for a year | $9.99 | $19.99 | All features for twelve months on one Mac; Lifetime is the route to more Macs |
Launch discounts: the code PHPROMO20 takes $4 off Lifetime, bringing it to $10.99. The Product Hunt launch post described the code as good for the first 100 buyers; the current banner on isurgemac.com says the launch offer covers the first 1,000 customers. Nothing renews by itself on either tier. And if you had iSurge before version 0.4, it stays free for you permanently.
What Mistakes Should Beginners Avoid?
Common wrong turns people make with iSurge in the first week:
| Mistake | Why it backfires | Do this instead |
|---|---|---|
| Buying for an Intel Mac | iSurge does not run on Intel Macs at all — Apple silicon (M1 and later) only | Check Apple menu > About This Mac; buy only for M1+ |
| Expecting notch features on a notchless Mac | The notch stats need a MacBook with a notch | Everything else works on any supported Mac; only the notch-specific stats need the notch |
| Assuming macOS 26 Tahoe is required | It is not — macOS 15 Sequoia or later is enough | Update to Sequoia or newer; no need to chase the latest OS |
| Denying the Keep Awake helper, then wondering why lid-closed mode fails | That mode's privileged helper needs your explicit permission | Allow it at setup, or re-enable it in Settings when you first need lid-closed Keep Awake |
| Reading the "macOS System" row as an exact figure | macOS hides per-process usage for most system processes | Treat it as what macOS is willing to share, not an audit |
| Searching "iSurge" and installing something else | The name collides with Surge.sh, Surge 5, Surge XT, and ISURGE tablets | Download only from isurgemac.com — the Mac app by Ruthran |
| Expecting a free tier or trial | There is none — paid license only, no account to sign up for | Read the 14-day money-back terms before buying; past-0.4 owners are free anyway |

Frequently Asked Questions
Is iSurge free?
No. iSurge is a paid app with no free tier and no account system — $14.99 once for Lifetime (regularly $29.99) or $9.99 for a year (regularly $19.99), launch prices as of November 2026. If you had iSurge before version 0.4, it stays free for you.
Does iSurge work on Intel Macs?
No. iSurge requires Apple silicon (M1 and later) running macOS 15 Sequoia or newer. The notch features additionally need a MacBook with a notch; all other features work on any supported Mac.
How is iSurge different from Activity Monitor?
iSurge reads the same macOS data but groups a thousand processes into the apps you recognize, normalizes CPU percentages to the whole machine instead of per-core math, keeps two live stats beside the notch at all times, and names the apps behind strain warnings — with a quit button on each app's row.
Is the PHPROMO20 code still valid?
The $4-off code brings Lifetime down to $10.99. The Product Hunt launch post limited it to the first 100 buyers; the current banner on isurgemac.com says the launch offer covers the first 1,000 customers. Check the site's banner before buying — launch offers expire.
Does iSurge send my data anywhere?
According to the maker: no account, no analytics SDK, sound is never recorded, and stats, history, and settings stay on your Mac. The app goes online only for updates, license checks, and extras like song covers and weather.
