Hi, I currently use my (old v1) iPad as a guestlist by using pages and manually searching. it's not particularly elegant, however and it can be super slow. And the guestlist specific apps I've seen are way too expensive and have features I really don't need. What I'd like is to be able to search a list of email addresses super quickly and easily and preferably be able to check people off super quickly and easily (though this is a bonus, not a must have). Any thoughts?
