It doesn't appear to save any settings after closing and re-opening the app. There is also a 2-3 second lag from when I reach the said speed and the actual adjustment. Not big deals, other than that it appears this will work pretty good on the water....for free! But I'd certainly pay a few bucks for a better app that would resolve these issues....
I tried a few android volume control apps and they all had problems. They were either missing features or would not run reliably. I decided to write my own. It's still a work in progress, but it seems to work. I've only tested it on my galaxy s3, but I think I set it up so it will work on devices running older versions of android. It's pretty basic. You enter a speed for volume control to start at, a speed for it to end at, a min volume and a max volume then hit start. The app pulls the speed from the gps and linearly adjusts the volume from the min to the max. You can save your settings, and it will automatically load them when you restart. I've been meaning to put it in the google play store, but haven't had the time to create the icons for it. For now it's up in my dropbox folder.
