CoolGuard keeps an eye on your phone's heat — and at night, it's the clock on your nightstand. A hot iPhone runs slower, its battery ages faster, and in summer it heats up within moments in the sun or while gaming, navigating, or charging. CoolGuard shows you where your phone stands on a four-level scale (Normal, Slightly Warm, Hot, Critical), warns you in time, and tells you what to do. HEAT MONITORING • Live heat level on the main screen, with a color-coded ring and a quick tip • Heat Trend: 1-hour and 24-hour curves in a banded or clean style — drag your finger to read the details • Heat Log with calendar and map: when and where your phone got hot • Alerts from the level you choose: push notifications, sound alerts, quiet hours • Monitor Mode: background monitoring, with a Live Activity on the Lock Screen and in the Dynamic Island • Cooling tips and a carefully curated selection of active coolers NIGHT CLOCK AND ALARM • Sleep Mode: dark screen with just the clock and the outdoor temperature — three sizes, your choice of color • Alarms: up to 10, repeating daily; on iOS 26 and later they ring through the system alarm, even when your phone is silenced • Landscape view: big clock, swipeable alarm bar, brightness slider • Burn-in protection: slow pixel drift and dimming to keep your display safe • 12- or 24-hour clock, with seconds if you like WEATHER • Outdoor temperature, with today's and tomorrow's highs and lows • Weather face in the ring: the sun and moon travel around it from sunrise to sunset • A warning on dangerously hot days WIDGET • Small: thermometer, weather, battery level, clock • Medium: adds the heat trend curve and the date • Works on the Lock Screen, too BATTERY • Battery Health and cycle count, compared month by month with your phone's heat MORE • 50 languages, Celsius or Fahrenheit • Private by design: no ads, no analytics, no accounts — your Heat Log never leaves your phone • Free — you can support development with a tip Note: iOS doesn't expose exact temperatures to apps — CoolGuard shows Apple's four official thermal levels.

Scam Check helps you assess suspicious messages, links, screenshots, QR codes, and phone numbers before you respond. Paste an email, text message, or chat, or use a screenshot, the camera, or the built-in QR code scanner. The app checks for common scam indicators, including urgency, requests for passwords or personal information, unusual payment demands, remote-access requests, and suspicious web addresses. Detected phone numbers can also be checked online with privacy in mind. The number itself never leaves your device; only a cryptographic hash is sent. Results may include public enforcement information from Germany's Federal Network Agency and pseudonymous community reports. You get: • an easy-to-understand risk level • a transparent risk score • the warning signs that were detected • clear next steps • an overview of detected links • optional phone-number checks using cryptographic hashes • pseudonymous community reports about suspicious numbers • an optional local history of your checks • practical safety guidance Your content stays private: Analysis and text recognition run locally on your device. Messages, photos, QR content, and phone numbers are not sent to the developer. You can disable online phone checks at any time, and local history can be cleared or turned off completely. Scam Check is an informational tool and cannot guarantee that every result is correct. No report does not automatically mean a number or message is safe. If money, account credentials, or immediate harm are involved, contact your bank, the organization through an official channel you found independently, or local law enforcement.
