Timers & sound tools
Water boil timer, emergency whistle, frequency generator, CPR metronome, and stopwatch.
Water Boil Timer
Calculates the boiling point and recommended boil time based on your altitude. At higher altitudes, water boils at a lower temperature and needs to boil longer to be safe.
Emergency Whistle
Plays three short blasts — the international distress signal. Much louder than yelling and carries farther.
CPR Metronome
Helps maintain the correct compression rate (100-120/min) during CPR. Follows the 30:2 ratio (30 compressions, 2 breaths).
Frequency Generator
Generates audio frequencies. Can be used for testing hearing, animal deterrence, or signaling.
Stopwatch
Simple stopwatch with lap functionality.
