Thermomator: Heat Monitor

Your iPhone gets hot. Then your game stutters, your video stops recording,
and your battery quietly loses capacity you never get back.

Thermomator shows you the moment it happens — live, on your Lock Screen and
in the Dynamic Island.

WHAT'S ACTUALLY GOING ON

iOS is constantly deciding how hard your device is allowed to work. When it
gets too warm, it throttles: frames drop, 4K recording halts, charging
slows to a crawl. You feel all of this. You almost never get to see it.

Thermomator makes that invisible decision visible.

- Live Activities — watch your thermal state change in real time in the
  Dynamic Island, on the Lock Screen, or in StandBy.
- Widgets in three sizes — a glance is enough.
- Chart View — see exactly when your device crossed the line, and for how
  long it stayed there.
- Notifications — know the second iOS starts holding your device back.
- History and export — CSV or JSON, for when you want the receipts.
- Full iPad support, sidebar and all.

ABOUT TEMPERATURE READINGS — PLEASE READ

Apple does not let any third-party app read your device's internal
thermometer. If an app is showing you a CPU temperature in degrees, it is
guessing.

Thermomator doesn't guess. It reports the official thermal state that iOS
itself uses — Nominal, Fair, Serious, Critical — which is the value that
actually determines whether your device throttles. It isn't a number in
degrees. It's the thing that number would have been trying to tell you.

We would rather be honest than impressive.

PRIVACY

No accounts. No tracking. No analytics. Nothing leaves your device, ever.
Your thermal history is yours.

FREE AND PRO

Free: live dashboard, Live Activities, notifications, and a widget. The
core of the app — knowing when your device is throttling — stays free.

Pro: full history, Chart View, CSV and JSON export, and all widget sizes.

Anyone who downloaded Thermomator before version 2.0 has Pro for life, at
no cost. Features that were once free will never be taken away.

Built by one person, in Tokyo, during a very hot summer.
