What it does

🩺

Causes at a glance

Live thermal state, a quick symptom check and AI intake fused into ranked causes — every one with its evidence.

💯

Health score

Five weighted dimensions (heat, battery, storage, memory, load), 0–100, with fully transparent rules.

⚡️

Actionable fixes

Every fix includes the exact Settings path — and deep links straight to Battery, Storage and Background Refresh where possible.

📚

Phone basics

Why phones get hot and slow — the actual mechanics, in plain words.

Privacy promise

Your diagnostic data stays on your phone by default: history is stored only on device (and in your own iCloud backup). No account, no ads, no tracking. AI analysis runs on-device whenever possible; in cloud mode only the minimal summary of a single analysis is sent, and our servers never retain conversation content.
