Bioacoustics application that gives current temperature readouts by listening to crickets! This app uses the iPhone's built-in microphone to detect the chirping of Tree Crickets, and computes a temperature value based on the rate of chirping. The readout is usually accurate to within a degree or two.

Note: CricketSong listens for snowy tree crickets, which have a very rhythmic chirping, and filters out other crickets, like field crickets, which are more sporadic when they chirp.

Works best within 20 feet of a tree cricket.

Happy Chirping!

What's New in Version 1.2

- Information page about snowy tree crickets
- Audio samples to help you recognize tree crickets.
- Display temp in Fahrenheit or Celsius
- User interface improvements.

Good, when it works

"CricketSong" is a promising app, unfortunately, it does not deliver on its promise. I tested it with both live tree crickets and recordings of tree crickets taken at different temperatures and, when it worked, the app calculated the correct temperature. Unfortunately, the app fails to hear the sound of a singing cricket even when the iPhone is a couple of inches from the insect, or when the call is blaring through the speakers. The "Signal strength" indicator of the app appears to show random numbers that do not relate in any way to the actual volume of the sound, and in 8 out of 10 times the app failed to hear the cricket's call and calculate the temperature.

Needs major update please

This app does not work on iOS 9. Please update it ASAP.

Needs ability to share temperature readings to a user generated cloud database and map.

Needs ability to also show average temp from collected readings.

Needs ability to keep a log of temperatures gathered and their GPS location/altitude/date/time and show all on a map.

Great app

Very neat! Very accurate!
