About 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.

Bug fixes and improvements. Restored Live Activities and widgets for everyone who had Thermomator before 2.0 — Pro, free, permanently. Included in this version: Changes in Thermomator 2.1.1 - If you downloaded Thermomator before version 2.0, you now have Pro for life at no cost.

Anything I charge for from now on will be something I've added, never something I've taken away. - Thank you to everyone who told me plainly. It changed how I'm building this app. Changes in Thermomator 1.2 - All new widgets: Monitor your device's thermal status at a glance. Always up to date with the latest status. - Export your thermal history to CSV or JSON. - Fixed an issue where real time thermal state update notifications stops working under certain conditions.
