User reviews

Great app

Good when digital nomading to see how long you’ve been in certain countries.
Would love to see Visa rules on top of Tax rules. Currently it tracks how long before I need to pay taxes, but knowing when I need to do a border run at 90 days would be great too

Perfect

I split time between Florida and Illinois for work and I’m sick of worrying if I’m remembering to track every trip right. This totally takes care of it!
