Thermometer: Digital Room Temp is a digital thermometer, hygrometer, and local weather station application designed to display indoor room temperature, relative humidity, and outdoor atmospheric conditions on a classic seven-segment Liquid Crystal Display (LCD) interface. Whether you are monitoring bedroom comfort with an external Bluetooth sensor, checking indoor humidity levels, or reviewing local outdoor weather before heading outside, Thermometer: Digital Room Temp presents essential climate metrics in a distraction-free layout. HOW MEASUREMENT WORKS (TRANSPARENCY NOTE) - Outdoor Weather Mode: Uses Global Positioning System (GPS) location or manually saved cities to retrieve real-time outdoor temperature, feels-like temperature, relative humidity, barometric pressure, wind speed, visibility, Air Quality Index (AQI), and pollen data from local weather stations. - Indoor Room Sensor Mode: Because smartphones do not contain built-in ambient room temperature sensors, live indoor room thermometer and hygrometer readings are measured by pairing a compatible external Bluetooth Low Energy (BLE) temperature and humidity sensor. A built-in Demo Sensor mode is also available to preview indoor display features without hardware. CORE FEATURES - Indoor and Outdoor Temperature: Switch seamlessly between outdoor weather station data and connected Bluetooth indoor room sensor readings. - Hygrometer and Relative Humidity: Track indoor and outdoor humidity percentages alongside daily minimum (Min) and maximum (Max) temperature memory. - Detailed Atmospheric Metrics: View feels-like temperature, barometric pressure in hectopascals (hPa), wind speed and direction, visibility distance, cloud cover, Air Quality Index (AQI), and pollen levels. - Classic Seven-Segment LCD Interface: Read measurements from across the room with a high-contrast digital thermometer display that supports both portrait and landscape desk clock orientations. - Customizable Display Themes: Choose from 11 retro and modern Liquid Crystal Display (LCD) color themes, including Classic Green, Retro Gray, Amber, Ice Blue, OLED Dark, and Terminal. - Home Screen and Lock Screen Widgets: Check live temperature and humidity updates directly from your iPhone or iPad screen without opening the application. - Multi-Location Weather Tracker: Monitor your current Global Positioning System (GPS) location and save multiple cities worldwide. - Unit Conversion and Live Clock: Toggle instantly between Celsius (°C) and Fahrenheit (°F) and track time with an integrated digital clock showing hours, minutes, and seconds. COMMON USE CASES - Connecting a Bluetooth Low Energy (BLE) room thermometer sensor to monitor bedroom, nursery, office, or living room climate. - Using your device in landscape mode as a desktop digital thermometer and weather clock. - Checking outdoor temperature, humidity, wind, and air quality before commuting or traveling. - Tracking room humidity and temperature to help manage Heating, Ventilation, and Air Conditioning (HVAC) comfort. OPTIONAL PRO FEATURES Thermometer: Digital Room Temp includes core outdoor weather and temperature display features for free. An optional PRO upgrade unlocks Bluetooth room sensor integration, Home Screen and Lock Screen widgets, all premium Liquid Crystal Display (LCD) themes, unlimited saved locations, and extended atmospheric metrics (wind, pressure, air quality, and pollen). Download Thermometer: Digital Room Temp to use a clear, reliable digital thermometer and weather monitor every day. And remember, Thermometer: Digital Room Temp keeps your indoor sensor readings and outdoor weather data accessible in one clean interface.
