I am somewhat of a guitar noob myself (played since winter 2002), but i felt i had to say something, tuning aids are ok when you have them but when you don`t, and need to play the guitar you woud wish you would just learn to tune it "by ear"
Tuning a guitar by ear is no problem, even for tone deaf people, just try listening to the pitch of the vibration, instead of the tone itself. sounds kinda like this.
vehov-veeohov-veeehov-veeeeehov-veeeeeeeeeeeehov-veeeeeeeeeeeeeeeeeeeee.... (no vibration)
Starts of as a high frequency vibration, and then it drops in Hz the closer you get to the right tone. once the string has the right tension compared to the string youre tuning after the "vehov" vibrations copletley disapear, and if you go to far it starts off slow and increases the frequence (an opposite "vehov" scale)
Offcause this is no use unless you have a referance point to get a clean "E" on the first string or what ever string you tune after.
Here in Norway, the standby dail tone in house phones is always an "A" so i sometimes tune the guitar after my house phone. (not mobile)
It`s a great app, but if you have to tune without tuning aids for a while, you can do this blindfolded
