Photo sharing
What is the photo app everyone is using?
It depends what for. For posting, the app everyone is using is Instagram. For storing, it is whichever came with the phone: Google Photos on Android and iCloud Photos on iPhone, which is why most people never chose one. For sending photos to friends, it is WhatsApp in most of the world and iMessage between iPhones in the US. The gap is pooling: when 30 people at one party each have photos the host wants, none of those apps does the job cleanly, because each one either compresses, scatters the photos across chats, or needs every person on the same platform. That is the job QR-code event albums exist for, and it is why they appear at weddings, birthdays, and reunions rather than in the app charts.
The defaults, and why they are the defaults
Google Photos and iCloud Photos are used by almost everyone because they are pre-installed and back up the camera roll automatically. Nobody picks them; they are simply where the photos already are. That makes them excellent libraries and mediocre collection tools, since contributing to someone else’s album means holding an account on their platform.
Instagram is the app everyone posts to, and it shapes the photos to fit: square or 4:5 crops, recompression, and an account you cannot cleanly export from. It is where photos go to be seen, not where they go to be kept.
WhatsApp is the app everyone sends with. It reaches every phone, and by default it compresses every image it forwards. A group chat after a party is 200 photos from 15 people, in order of arrival, mixed with the conversation.
The app nobody has installed, on purpose
The tool that collects a room’s photos into one place is usually not an app at all. A QR code on the table opens a web page; the guest picks photos from their camera roll and uploads in about 3 taps. There is nothing to install, so "everyone using it" is never a requirement — it works for the guest who has never heard of it.
The host gets one album with every upload held for approval, a live wall on the paid plans that can be shown on a screen at the venue, and a ZIP download of the originals afterwards. Gathmo’s free plan covers 60 items and 30 days; paid plans are one payment per event.
So the honest answer to "what is everyone using" is a list of four apps that each do one thing well, and a fifth kind of tool that does the one thing none of them do.
Common follow-ups
Is there a trend toward disposable-camera apps at parties?
Yes, and they work by making every guest install the same app. A QR album gets the same photos without the install, which is why it collects from more of the room.
Can I still post the photos to Instagram afterwards?
Of course. Download the originals from the album and post what you like. The album is where they are collected, not where they have to stay.
Does a QR album work on both iPhone and Android?
Yes. It runs in the phone browser, so any phone with a camera and a browser can scan and upload.
