I bought the Pro version on 6 January 2015. The program works well BUT the only sound that interested me and I chose to be the most suitable for my needs, was defective; has NOISE; is the DOORBELL. The same day I warned the author, who kindly responded the next day. He appreciated the information and reported that seek to incorporate the correction in the next version. I write this on January 24, 2015, when, unfortunately, the sound has not yet been fixed. In the program I did not found an appropriate tone to use it in the MEDITATION sessions; therefore I chose the sound closest to what is desirable but it has that unpleasant noise. I regret that the noise has not been corrected. Otherwise, the program works fine.
