I don't think you'll find one without fitness functions, but on all of them you can largely ignore the fitness functions.

For mapping, what functions do you need, and what's your budget? You can get cheaper units that just show a map (and perhaps overlay a preplanned route) o'r more expensive units that do true satnav-style navigation and can re-route on the move (eg Hammerhead). Knowing your budget would make this easier.

(And with all that said, probably your best option is an old Android phone off eBay and a handlebar mount to run one of the many mapping programs)

I suspect it doesn't post twice, but rather posts once and (temporarily) displays it twice to the poster

That's a useful feature, but I think what the other person meant was posts on the front page. A lot of Reddit apps let you permanently/temporarily hide posts that you'd already seen, which was really useful as a way of 'resetting' your feed when you've already scrolled through it recently

I'm trying them all. As of today, Connect for Lemmy seems to be working the best
