Gadsmoots, I love this app

I’m an American, so obviously I’m not about to embrace the metric system. But smoots? Hell yes. This is a delightful app.

Love that it's offline!

Insanely accurate and completely offline. I love the sense of humor built in as well!

Fantastic app!

So great to have an app that just works without being connected to a network. No passwords and usernames.
Just raw functionality! Also knowing your elevation in “giraffes” is just fun.
