Features & Capabilities

Your phone is hot, your game stutters, recording stops, and your battery ages. Thermomator shows you the moment iOS starts throttling, live in the Dynamic Island.

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.

User Reviews

I think this app is nice. Shows the temperature of the device easily. Though there’s one thing that I personally would like and could maybe get more users. I feel that support for at least down to iOS 18 would be nice. Especially for say the iPhone XR or iPhone XS

Update: The change has been undone and previous of the app now have Pro for free. Thanks to the dev for listening to feedback, however note that you have to press the restore button if you deleted the app and reinstalled it. I thought this app was really cool. I really did. The design is beautiful and it had a good UI. Recently after updating, I find that already existing features from older versions of the app have been PAYWALLED after a recent update. I will not be supporting an app developer who is adding greed to a thermal monitoring app. I think the fact that it’s paywalled is absurd. Goodbye thermomator, you were good while you lasted.
