Is It Hot? – Thermal Check

iOS won't tell apps the exact temperature — but it does report thermal state. Is It Hot? shows it live, with clear cool‑down steps when your phone is actually running hot

Is your iPhone running hot? Is It Hot? gives you a clear, honest answer at a glance — and tells you exactly what to do about it.

iOS deliberately does not expose an exact temperature reading to third‑party apps. Any app claiming to show "42.7°C" is guessing. Is It Hot? does it the right way: it reads the official system thermal state — the same signal iOS uses to decide when to throttle performance — and shows it on a live gauge.

WHAT YOU GET

Live Thermal Gauge See your device's thermal state in real time: Nominal, Fair, Serious, or Critical. The gauge updates the instant iOS reports a change.

Smart Cool‑Down Tips When your phone is actually hot, you get clear, context‑aware steps — close demanding apps, unplug from charging, take the case off, drop the brightness. When everything's cool, it simply tells you so. It even warns you never to put a hot phone in the freezer (condensation can permanently damage it).

PRIVATE BY DESIGN Is It Hot? collects nothing, sends nothing, and has no accounts, ads, or trackers. Every reading comes straight from your device and never leaves it. There's no network request to any server, ever.

HONEST ABOUT LIMITS We won't fake a precise temperature that iOS doesn't provide. The thermal gauge shows the real, official signal for heat and throttling — which is exactly what you need to know whether to worry.
