Do we still need a professional photographer?

Yes, if you wanted one before: Eventphoto.io does not replace a professional photographer, it collects what your guests shoot on their phones, and the two do different jobs.

A professional gets the portraits, the ceremony and the shots that need someone who knows what they are doing; the guests get the table you were not sitting at, the dance floor at midnight and the ten minutes the professional spent changing a lens. The gallery is where that second half turns up, and it is full before the band has packed up.

The two do not get in each other's way. Guests upload from their camera roll, so nobody stops shooting for the professional, and the gallery asks nothing of them. The service is not built for photographers and does not host or deliver their work; it is for the couple, the hosts and the planners.

If you are weighing the two because of budget, they are not the same purchase: the paid plan is $19.99 (£15.99 in the UK) once for the whole event, and the free plan takes 20 photos per guest for nothing, so the question is not either-or. What the guest gallery replaces is the shared album nobody fills in afterwards and the disposable cameras on the tables, not the person you hired for the day.
