Tell Me When app for iPhone and iPad
Tell Me When is a fun and easy to use application which notifies you when a certain threshold has been reached or passed, based on rules you create. It uses the relayr WunderBar to gather information about temperature, humidity, light, proximity, noise, and movement. Just choose the measurement type you wish to be notified about, set an appropriate threshold and get notified whenever the threshold is exceeded. Its as simple as that!
