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.

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. **Developer response:** I'm sorry. Putting features behind a paywall that were already free was a shortsighted decision, and reading your review made me realise how it must have looked from your side. You'd been using Live Activities and widgets since 1.1, and then one day I just took them away. I don't really have a good excuse for that. I've released 2.1.1. Anyone who had Thermomator before 2.0 now gets Pro for life, for free. You don't need to buy anything or restore anything, just update and it should all be back. From now on I'll only charge for things I actually add. Thanks for being honest about it. It genuinely changed how I'm thinking about this app, and I'd be really glad if you gave it another try. Haruhiro ### 1/5 — New update makes you pay *2026-07-11* New update makes you pay for old features that used to be free. Renders the app useless. **Developer response:** Sorry about this, and thank you for reporting it. Locking Live Activities and widgets behind Pro after they'd already been free was shortsighted of me, and I've undone it. With version 2.1.1, if you had the app before 2.0, you've been given Pro for life at no cost, so both should be working again after you update. If they're still not working, please email me at haruhiro@bybeit.app and I'll look into it straight away. Haruhiro ### 1/5 — This app contains paywall *2026-07-09* They are changed to updated affect economy Live activity and widget cannot granted **Developer response:** Sorry about this, and thank you for reporting it. Locking Live Activities and widgets behind Pro after they'd already been free was shortsighted of me, and I've undone it. With version 2.1.1, if you had the app before 2.0, you've been given Pro for life at no cost, so both should be working again after you update. If they're still not working, please email me at haruhiro@bybeit.app and I'll look into it straight away. I'd rather fix it than leave you stuck with a broken app. Haruhiro ### 1/5 — Paywalling. *2026-07-05* I thought this app was really cool. I really did. The design is beautiful and it had a good UI.
