Tools

Lirum Device Info includes a suite of tools for live monitoring, diagnostics, and reference lookups.

Availability varies by device and platform (iOS/iPadOS/visionOS/macOS Catalyst), and some tools require permissions (for example Camera, Microphone, Bluetooth, NFC, and Location).

Open Tools to access diagnostics and live monitors.
Scroll to find more tools.
