Frequently Asked Questions
Quick answers for safety, device status, purchases, audio, and privacy.
Does Phone Warmer turn my iPhone into a heater?
Phone Warmer intentionally runs foreground CPU and graphics activity, which consumes battery and can warm the device. It reduces its workload according to the selected thermal target, throttles at Hot, and stops its added workload at Critical. This does not make an iPhone a safe or reliable heater. Do not rely on it for survival, medical care, or protection from extreme cold; use proper clothing and purpose-built warming equipment.
What devices does Phone Warmer support?
Phone Warmer is built for iPhone on iOS 18 or later.
Why does the app show thermal status instead of exact temperature?
iOS does not expose an exact internal phone temperature to apps. Phone Warmer uses Apple's thermal status categories and avoids presenting fake degree readings.
What should I do if my phone gets hot?
Stop using the app, let the device cool, remove it from direct heat or enclosed spaces, and follow any iOS temperature warning. Do not place a hot device against skin.
Does Phone Warmer need an account or internet connection?
No QnSub account is required for core use. The App Store may require a network connection for purchases, restore purchases, and normal Apple services.
What does Pro unlock?
Phone Warmer Pro is a one-time purchase that skips the 15-digit number check for changed intensity requests from 40% to 100%, including Warm and Hot. It does not remove thermal safeguards. The App Store displays your local price before purchase. Buy Pro or use Restore Purchases in Settings. Completing 100 correct number checks also earns a local bypass, which factory reset or deleting app data clears; App Store purchases remain linked to your Apple ID.
Can I turn off animation or audio?
Yes. Phone Warmer includes reduced-animation support and calming music settings, including an Off option for silence.
Where can I read the privacy policy?
The full policy is at /phonewarmer/privacy. Short version: Phone Warmer is local-first, has no account requirement, and does not include advertising or analytics SDKs.
