The new app has more predefined dice (A-Z, 0-9, ...) and supports the iPad multitasking (split view,...) of iOS9.

Cook your easter eggs with Boiling

It is widely known, that the boiling temperature of water isn't constant. It depends on the air pressure. Only for the mean pressure at sea level it will be 100°C (212°F). Therefore with rising altitude the boiling temperature will drop quickly. On Mount Everest it is 68°C (154 °F) only. Why bother? The time to cook eggs depends on the temperature, which means above sea level it takes longer to cook them to perfection.
So far you could have used my Boiling app to calculate the boiling temperature for any altitude. But many modern smartphones come with a internal pressure sensor (e.g. the iPhone 6, the Nexus 4). So with the new version of Boiling you can calculate the water boiling temperature for your current air pressure which not only depends on your current altitude but on the current weather as well.

Happy cooking!

Air Pressure - New App for iPhone, iPad and Android

Air Pressure shows the current local air pressure (in hPa/psi, Torr, atm, altitude above sea level and percent of average pressure at a reference altitude), measured by the internal pressure sensor (if available) or a nearby weather station for which it uses your current location. The background color changes with the pressure value.

  • the background color changes with the pressure value
  • the pressure is automatically updated
  • set a reference altitude: current altitude, sea level or custom altitude
  • pressure units: hPa/psi, Torr, atm, altitude above sea level and percent of average pressure at a reference altitude
  • compare with reference pressure at a reference altitude
  • the location is automatically updated when you move
  • metric and imperial units
