Frequently asked

Why "Laimen"? What does it mean?

"Laimen" is a phonetic spelling of limen — Latin for "threshold." In psychology, the limen is the smallest change in a stimulus you can perceive: barely noticeable, but enough to register. That's exactly what the app aims for — a soft glow at the edge of your screen that sits right at the threshold of attention, present without demanding it.

Is Laimen free?

Yes. The free tier lets you set up to 2 active reminders at no charge, forever. Pro unlocks unlimited reminders.

What do I get with Pro?

Unlimited reminders, plus priority support. It's a one-time purchase — no subscription, no renewal fees.

How does payment work?

Purchases are processed securely by LemonSqueezy. You'll receive a license key by email; enter it in the app's settings to activate Pro.

Does Laimen send data to the cloud?

No. All reminders, settings, and statistics live in a local SQLite database on your machine. No telemetry, no cloud sync.

Can I use Pro on multiple computers?

A Pro license activates on one device. Contact us if you need to transfer it to a new machine.

What platforms are supported?

Windows 10+ (64-bit), macOS (universal), and Linux (deb, AppImage, rpm) are all supported. Builds are currently unsigned on all platforms, so the OS will warn on first launch — pick your platform below to get past those prompts.

Windows: SmartScreen / Defender blocked the installer

Laimen's Windows MSI isn't code-signed yet (a code-signing certificate is on the roadmap), so SmartScreen treats it as an unrecognized publisher. The download itself is fine — it comes straight from this site, served from the latest GitHub Release.

To run it anyway:

On the blue "Windows protected your PC" prompt, click More info .

Click Run anyway .

If Defender quarantines the file, open Windows Security &rarr; Virus & threat protection &rarr; Protection history and choose Allow .

If your browser refuses to download the MSI at all, click the chevron next to the warning and pick Keep / Keep anyway.

macOS: "Laimen cannot be opened because the developer cannot be verified"

The macOS DMG isn't notarized yet (Apple Developer signing is on the roadmap), so Gatekeeper blocks it on first launch. The easiest workaround:

Open the DMG and drag Laimen.app into Applications .

In Finder, right-click (or Control-click) Laimen.app and choose Open .

Click Open in the dialog. macOS remembers the choice for future launches.

On macOS Sonoma and later the right-click trick may no longer be enough. In that case open System Settings &rarr; Privacy & Security , scroll to the bottom, and click Open Anyway next to the Laimen entry.

If macOS still refuses with a "damaged" message (common when Safari sets the quarantine flag on the DMG), strip the quarantine attribute from a terminal:

xattr -dr com.apple.quarantine /Applications/Laimen.app

Linux: the app won't launch or the AppImage won't run

Linux builds are unsigned and don't ship through a software center, so a couple of small steps are usually needed.

AppImage — mark it executable before running:

chmod +x Laimen-*.AppImage<br>./Laimen-*.AppImage<br>If it exits silently, Laimen needs a WebKitGTK runtime. On Debian/Ubuntu:

sudo apt install libwebkit2gtk-4.1-0 libayatana-appindicator3-1<br>On Fedora: sudo dnf install webkit2gtk4.1 libappindicator-gtk3. On Arch: sudo pacman -S webkit2gtk-4.1 libappindicator-gtk3.

.deb / .rpm — install with your package manager so dependencies are resolved automatically:

sudo apt install ./laimen_*_amd64.deb<br># or<br>sudo dnf install ./laimen-*.x86_64.rpm<br>The tray icon needs an AppIndicator-compatible status area. On GNOME, install the AppIndicator and KStatusNotifierItem Support extension; on KDE/XFCE/Cinnamon it works out of the box.

How do I get Laimen to start automatically at login?

Open Laimen's settings window and enable Start at login . That registers Laimen with the OS so it launches...
