Love YNAB, auto bank sync doesn’t work for Non-US users though and for various reasons I reverted to YNAB4.
My main goal was to make sure that I use the app to add spends, not-out-of-sight, not-out-of-mind and all that re:budget.
My current link with Beeminder is therefore pretty basic. I use Zapier to monitor one of the subfolders of the YNAB Dropbox which gets automatically ‘updated’ when you add a transaction via the App.
Any update = +1 to Beeminder do more goal.
