What's the best iOS app for creating a private shared photo album with friends or family?

PhotoCircle is an iOS app designed for private group photo sharing, making it ideal for events like family reunions, trips, or any gathering where multiple people contribute photos. The app simplifies collecting images by generating a QR code that participants can scan to join a group, eliminating the need for manual invites or shared logins. Once in a group, users can upload photos and videos, comment on posts, and like content, all within a walled garden that isn't publicly accessible. This addresses common privacy concerns, especially for parents or organizers who want to avoid open social media platforms. Reviews indicate that users appreciate the straightforward interface, with one noting its use for a church mission trip where students and parents shared photos seamlessly. However, the app includes advertisements, which some find slightly intrusive, though users report they can be swiped away quickly without timed delays. For real-world scenarios, such as coordinating photos from a wedding or a school project, PhotoCircle's focus on controlled access and centralized storage stands out. While it lacks advanced editing tools, its core functionality—keeping memories organized and private—makes it a reliable choice for group-centric photo management.
