From CCD Aherne Juhnke Scharf GbR:
Oh, Uh, Yeah, hmmmmmA sigh, something humdrum. We sigh on many occasions. Intentional or unintentional. We are creating laughs, amazement, antipathy and acceptance. We sigh on the stage of life to get over something. This was the basic idea when creating iSigh. We were practicing a lot while programming. Our best sighs are provided with the app. The fun gets better. Record your own sighs, combine it with a photo and have fun. Share the fun with somebody per email or have a nice memory of some moments you will remember. Well, does this make any sense? Maybe not, but its great fun anyhow.
