Do I need to install an app to do this?
No. Jitabi lives in WhatsApp, and the pages it builds open in any browser โ for you and for your guests. There is nothing to download for either side.
Can I edit the page from my phone after guests have the link?
Reply with the change and the page updates; that is the same conversation you started with. The link does not move, so everyone who opens it afterwards reads the current version.
Will the page look right on guests' phones?
Guests open the link in the browser on whatever phone they hold, press the reply button there, and land on the same page you previewed on yours. The experience is one screen wide at both ends.
What about adding lots of photos from my phone?
Supported occasions carry a photo gallery. A picture or two is a browser job anywhere; if you want the whole camera roll in, a computer pass is the comfortable way. The page never waits on it to go live.
Can I keep this private while working from my phone in public?
Until you publish, nobody sees the page โ drafts are hidden from guests by default. And a published page can carry a password, so a link glanced over a bus seat is not an open door.
