Guitar FX Deluxe (sample version included with EasyTune) costs $3.
If you are looking for an easy to use guitar tuner then EasyTune is exactly what you need. You don't have to hassle with different settings, just take your acoustic guitar and touch a string. The algorithm recognizes automatically which of the six strings you have chosen. You can fine tune the frequency of your guitar using the analog display with an accuracy of less than 1 Hz. With EasyTune your guitar will always be in perfect tune. In addition to the tuner, we integrated a digital guitar effect unit (Guitar FX Echo) for your acoustic guitar for free (only for iPhone / iPod touch). You can choose between 10 different echo effects and also control their gain level. The effects can be applied in realtime to any input signal e.g. an acoustic guitar ;-)
