Settings
Settings lets you manage updates, purchases, and a small set of preferences used across the app and widgets.
Table Of Contents
Updates
In Updates, you can:
- Check for Updates: checks whether an update is available.
- Install Update: appears when an update is available and opens the update progress flow.
Purchases
In Purchases, Lirum shows your current premium entitlements:
- Premium Status: one of four states -- Lifetime Active (has lifetime purchase), Subscription Active (has active subscription), Unlocked (full/Pro app version), or Free (Lite version with no purchases). A "last verified" timestamp shows when the subscription was last checked.
- Lifetime access: whether a lifetime purchase is active.
- Subscription: subscription status (shown on the Lite version).
- Subscribe to Premium: opens the paywall to purchase a subscription or lifetime access (shown on the Lite version when not subscribed).
- Restore Purchases: re-checks your App Store purchases (shown on the Lite version).
General Preferences
In General, you can configure:
- Measurement Units: metric vs imperial formatting for values shown across the app.
- Data Units: how byte sizes are formatted (base 2 vs base 10).
- Force Language: override the app language independently from the system language. Tap to open a searchable grid of language cards. Supported languages: English, Chinese (Simplified), Chinese (Traditional), Cantonese, Danish, German, Spanish, Finnish, French, Irish, Italian, Portuguese (Brazil), Portuguese (Portugal), Swedish, Ukrainian, Japanese, and Korean. Language changes take effect immediately.
Widgets
In Widgets, you can:
- Toggle Show Timestamp (controls whether widgets show a timestamp).
- Open Alerts to configure widget alert settings (see below).
- See Widgets for the full widget list and screenshots.
Alert Settings
The Alerts sub-screen lets you configure which alerts the Usage Alerts widget monitors. It includes:
- Quick Actions: Enable All and Disable All buttons.
- Six alert categories with individual toggles:
| Category | Alerts | Default Thresholds |
|---|---|---|
| CPU | Critical, Warning | Critical: 85%, Warning: 70% |
| Memory | Critical, Warning | Critical: 80%, Warning: 65% |
| Storage | Critical, Warning | Critical: <10% free, Warning: <20% free |
| Network | Warning | Warning: >50 MB/s sustained |
| Thermal | Critical, Serious, Fair | Based on system thermal state |
| Battery | Critical | Critical: <10% |
Alerts require sustained conditions (multiple consecutive samples meeting the threshold) rather than momentary spikes, reducing false positives.
Developer Options
Developer options are only available in debug builds. They include actions like copying logs and opening debug/log views.
