Temperature Alarm Clock uses the device's internal thermometer sensor to measure the surrounding environment's ambient temperature.

*IMPORTANT: Please note that this app requires that the phone has an inbuilt Ambient Temperature Sensor, in order to measure the surrounding temperature. Phones having this Sensor is a rarity nowadays, though. Hopefully this would change in the future.

Features:
• digital clock
• seconds counting
• create multiple alarms
• 12-hour or 24-hour mode
• full date format
• Displays the surrounding environment temperature
(*requires inbuilt Ambient Temperature Sensor)
• Displays the Low and High temperatures since the app started
• option to display temperature in °C Celsius or °F Fahrenheit
• option to dim backlight or set it to automatic brightness (may not be available on some devices)
• option for hourly signal
• option for keeping screen awake
• small icons at top of the display that indicate selected options
• supports both portrait and landscape orientation modes

Note: Temperature readings are only available if your device has an ambient temperature sensor.
