Look no further. This is it. Finally a logger that doesn't suck. If you need bullet proof GPS logging this is it. Can't belive how long it took me to find this app. It has exactly the options I need and no bloat. I was even considering writing such an app myself  because anything else was such a pain. So much bullshit and bloat on the market. And it can even auto log on device start.
