Free is not the problem. Signing in is.
A Google Photos or iCloud shared album costs nothing, but a guest has to be on the right platform and signed in before they can add a single photo. Picsui is a QR code — no account, no app, same on every phone in the room.

Where shared albums lose photos
Every one of these is a step between a guest and the photo they were happy to give you.
An account stands between the guest and the photo
A shared album asks a guest to be signed in to the right service before they can add anything. At a reception, holding a drink, that is where some people stop — not because they do not want to share, but because signing in is a task and they are at a party.
Guests are on different phones
An iCloud shared album is built around Apple accounts and a Google Photos album around Google accounts. Whichever you pick, some of your guests are on the other side of it.
The photos end up in someone else's library
Contributions live in the contributor's account. Guests can remove them later, and gathering everything into one place is a job you do afterwards.
Nobody is watching what goes in
Picsui events can hold uploads for your approval before anyone sees them. In a shared album, what a guest adds is there for everyone in the album.
Common questions
Is a Google Photos or iCloud shared album good enough for a wedding?
It is free, which is a real advantage, and if your guests are technical and all on one platform it can work. The usual problem is not the album — it is that a guest has to be signed in to the right service to add to it, and at a reception not everyone will.
What does a QR code change?
The guest scans and the camera roll opens in their browser. No account, no app, no platform. That removed step means any guest with a phone can add their photos, whatever phone or account they have.
Do guests need to download anything?
No. It opens in whatever browser is already on their phone, iPhone or Android, and works the same either way.
Can I still keep everything afterwards?
Yes. You download the full-resolution originals as one file, and the gallery stays up for twelve months. Nothing lives in a guest's personal library where it can quietly disappear.
