A warm visual focus, with device status in view.

Phone Warmer combines animated glass visuals, optional calming audio, and iOS thermal monitoring. Its adjustable foreground CPU and graphics activity consumes battery and can warm the device. Use briefly, stop if uncomfortable, and never rely on an iPhone for protection from extreme cold.

Phone Warmer does not turn your iPhone into a heater. It keeps the experience visible, foreground-only, and safety-aware.

A calmer interface for cold moments

The product is designed around large, simple controls that remain understandable when you are outside, wearing gloves, or just trying to keep moving.

Home

Start the ritual

Open one focused screen with a warm ember visual, large controls, and current device status close at hand.

Protection

Watch the device

See iOS thermal status, battery level, and Low Power Mode context so the session stays practical.

Settings

Tune comfort

Choose calming audio, reduce animation, review the safety disclaimer, restore purchases, and adjust supported preferences.

Understand the activity and its limits

Phone Warmer combines ambiance, movement-friendly design, device protection, and plain-language safety guidance in one iPhone utility.

Warm Visual Focus

A glowing ember and glass scene respond to your selected intensity. Foreground processing can warm the device; it does not make an iPhone safe or reliable heating equipment.

Thermal Awareness

The app shows Apple's thermal status language and avoids pretending it can measure an exact internal phone temperature.

Battery Protection

Battery level and Low Power Mode context stay visible, with safeguards that put device protection ahead of visual intensity.

Calming Music

Choose a soft built-in track or keep the session silent, with audio controlled locally on the device.

Glove-Friendly Flow

Large, direct controls and reduced-motion support keep the app usable when hands are cold or movement needs to stay simple.

Safety Disclaimer

The app is explicit: use proper clothing and purpose-built warming gear, and stop using a device that feels unusually hot or unsafe.

Simple enough for a cold sidewalk

Phone Warmer keeps the main loop short so it can be used during a commute, outdoor event, travel delay, or winter photo session.

01

Open the session

Use the Home screen as a calm visual anchor while you wait outside or take a short cold-weather break.

02

Check device status

Keep battery and thermal state visible so the app remains honest about what iOS exposes and what it does not.

03

Stop when needed

Follow the safety guidance, leave the session anytime, and use real cold-weather gear when conditions require it.

Local-first, clear about limits.

Phone Warmer does not require a QnSub account, ad SDK, analytics SDK, camera access, microphone access, or server account for core use.

Phone Warmer intentionally increases foreground processing, which uses battery and can warm the device. It is not purpose-built heating equipment, a medical device, emergency tool, thermometer, or replacement for warm clothing. Thermal safeguards reduce the added workload but cannot guarantee a safe surface temperature.

Stay aware. Keep moving. Protect your phone.

Phone Warmer is launching soon for iPhone. Built by QnSub Tech for people who spend real time waiting, traveling, walking, or working outside in cold weather.
