Lirum Device Info Documentation
Lirum Device Info is an iOS device diagnostics and device information app for iPhone and iPad. Use it for live monitoring (CPU, memory, storage, thermals, battery), hands-on hardware tests (screen, speaker, microphone, vibration, NFC, sensors), and detailed Apple device specifications.
Quick questions it can help answer:
- "Is my CPU or memory the bottleneck right now?"
- "What exactly is this iPhone or iPad model, and what are its specs?"
- "Is this sensor, screen, speaker, microphone, NFC tag, or connection behaving correctly?"
Built for developers, IT, and power users (and still friendly if you're just curious), Lirum focuses on clear visuals, useful context, and real data from Apple's public APIs.

Why Lirum
- 20+ built-in tools: monitors and hardware tests in one place (CPU/Memory/Storage/Thermals, sensors, NFC, display patterns, BLE metrics, local AI models, and more).
- Deep device specs: browse a large Apple device database with hundreds of fields per model, including CPU, Display, Camera, and Network details.
- Compare and explore: side-by-side device comparisons and an interactive timeline across iOS/visionOS generations.
- Practical troubleshooting: validate the stuff you actually use (touchscreen, microphone, speaker, vibration, location, Bluetooth, and more).
- Privacy-friendly by design: diagnostics are primarily on-device, and permissions are only requested when a tool needs them.

FAQ
Where do I find battery health, capacity, and charge cycle data?
Start with Battery Reports for analytics, and the Battery category for device-level details.
Which tools can I use for basic hardware tests?
Common quick checks:
Do I need to grant permissions?
Some tools require iOS permissions (for example Bluetooth, Location, Microphone, or Camera) to function. Lirum only prompts when a tool needs it. For policy details, see the Privacy Policy at https://lirumlabs.com/privacy-policy/.
