Used to work brilliantly and the coach voice in your ear is a great motivator, but began requiring me to login when I wanted to use it. When you're exhausted and just want to log a time, that's just hassle you don't need. But now I find there are occasions it just won't load and I have to uninstall/reinstall. If it wasn't for a) the fact that this app genuinely got me back into running & helped me get fit and b) all my run data is logged on it, I would have ditched it. Please fix it.
