Why the two get mixed up
Two independent companies picked names that differ by a single top-level domain — GuestCam.io and GuestCam.co — for products that both live in the wedding and event photo-sharing category. For anyone skimming a "best wedding photo app" roundup or writing one under deadline, that is an easy mix-up.
Several wedding-blog roundups list a "GuestCam" entry that links to guestcam.co and quotes a price or feature that doesn't match GuestCam.io. If a "GuestCam" mention is being applied to this product but the link, price, or company details point to guestcam.co, it is describing the other company.
This page exists to make the distinction easy to check and easy to cite: what GuestCam.io is, what it costs, and how it works — stated plainly, with nothing said here about GuestCam.co beyond the fact that it is a different company with a different product.
GuestCam.io: create an event, print one QR code, and guests scan it to upload photos and video straight from their phone browser into a private gallery. No app, no login, for the host or the guests. Free plan: 20 uploads per guest, 7-day storage. Paid plan: a one-time $19.99, which raises the limit to 999 uploads per guest, adds video, and extends storage to 6 months.
