Once you set up grade systems you want to compare, all you need to do is trivial swiping!

Easy and consistent

I’m in Australia and generally am converting YDS and French grades into Ewbanks... this app seems accurate and is super easy and efficient.

A cool addition would be to let users log their favourite climbs at each grade (include sport, trad, Boulder) - that way I could start comparing Flake Crack in Australia (17 trad) to other 17s (5.9 or 5c) around the world - with photos!

I like seeing multiple conversions at once
