Pretty much just use a phone for the basics but currently looking into GPS apps for recording sailing speed, watching the thread on personal locator beacons / Eperbs for obvious safety reasons. If I decide to go down this path I am thinking I would get a waterproof phone cover with earphones for listening to music as well. My question is, can I use a app (GPS) and listen to music at same time ? Currently have iPhone 5 but would consider buying android.

Go to the gps and speed forum, there's a couple of threads devoted to the logit app for speed sailing. and yes you can listen to music and listen to your speed at the same time

Next question. Downloaded a free phone tracker app, deleted after one day because it sucks to much battery and can't be switched of. Anyone know of a gps phone tracker app that can be switched of and only used when required ? Guess they work out in the ocean or do they require google maps to work?
