helps with tinnitus?
throckmeyer

I’ve been testing a new idea to reduce tinnitus, ie to listen to the pitch that matches the pitch i hear due to tinnitus. this app has easy to use features and good sound quality. i just wish it would run in the background so i can multitask while doing this therapy. i’ll let you know how well it works to reduce tinnitus. (the idea is the brain creates ringing in the ears to compensate for frequencies compromised due to damage to certain parts of the cochlea. if the auditory nerve can be stimulated at these frequencies, so the theory goes, maybe the brain will stop simulating them)


The update has created issues
LovelyLauraB

This has been a great app. The most current update stops/pauses when the screen locks or goes to sleep creating many issues especially for those who need to pop their phones in their pockets or have power saving/security modes on their devices. Please adjust ASAP!!


Best tool for an unusual problem.
Siengtom

Something was rattling in my car when playing music through my stereo. Problem was it would only rattle on certain bass notes and no song would create the rattle long enough for me to find it. It had driven me nuts for months! I picked up a cassette adapter to pipe my iPhone audio into my car stereo. Then I purchased this awesome App and immediately pulled up the Musical Note menu. Starting at the bottom, I began stepping up the note scale until BAM! There it was! I was able to reproduce the rattle. You won’t believe what I found. My spare garage door opener was vibrating inside my plastic glove box every time a bass guitar hit that note. From that moment, this Audio Function Generator from Thomas Gruber became worth 100 times what i paid for it. Thank You Tom! You rescued my driving sanity.

Free version works great for testing speaker foam repair! Advanced in app purchase price is also very reasonable for some amazing features.


Master Volume
Unlessyouarefree...

Great App But Needs A Master Volume That Controls Frequency Volume Within The App It’s Self, Independent From Other Apps Playing Through Same Speaker Systems Using iPhone Device. I Want My YouTube Playlist And Chimes Apps Layered Over Frequency.


Does just about everything I need
Recovering Gasaholic

I love this app. I've been studying and using frequencies for over 10 years now. I finally found an app that not only let's me go beyond whole number to decimals, but also let's me type in the exact frequency I want to run. No inaccurate sliders to fiddle with here. I use it regularly. I love the new sets feature. One thing I would like to see added is the ability to name the frequencies. I use different frequencies for different purposes. It would be nice to name Schumann Earth freq instead of having to memorize Earth is 7.83hz.


Awesome!!!!!
