Trips, clubs, family, fandom. The photos from that day are scattered across everyone's camera roll. Memory Log keeps a memory as one thing: the photos, the place, and the map. Share memories with a group of up to 20 people. WHAT EVERYONE SAVES LANDS ON ONE MAP - Save photos and a place together as a single memory - What your group posts appears on the same map and timeline as yours - People who join later can see past memories that remain in the group - Shared photos are stored in the cloud for 1 year after upload INVITING IS A QR CODE OR A LINK - You choose how long the link works and how many people can use it - Made a new link? The old one stops working - No account, no email address KEEP YOUR CIRCLES APART - Travel friends, a club, family — you can be in several groups at once - Switch from the top of the screen. The colour around the edge tells you where you are - Your own private space has no colour, so you always know when nobody else is looking YOU DECIDE WHAT LEAVES YOUR PHONE - Choose where each memory goes - "Remove from the group" and "delete everywhere" are separate choices - Notifications are per group PLACES YOU WANT TO GO, TOGETHER - Share "want to go" pins with your group - Been there? Turn the pin into a memory — the name, note, photo and link all carry over - Your own pin clears itself; pins other people added stay, for members who haven't been yet - Open any pin in Maps or Google Maps ALSO IN THE APP - Four ways to look back: Home, Timeline, Map, and Library - Year in review, a world map, and a travel passport - Tag filters, widgets, and reminders on the anniversary of a memory - No ads WHAT'S FREE - Keeping memories is unlimited — both how many, and how many photos in each - Joining groups you're invited to, and receiving everyone's memories, is unlimited too - You can share up to 15 memories of your own (3 photos each). Unshare one and the slot comes back - You can create up to 5 groups (family, trips, clubs — keep them separate) MEMORY LOG PRO (one-time purchase) - Share unlimited memories with your groups - Share up to 99 photos per memory (up from 3) - Create as many groups as you like - Backup and restore, travel footprints, PDF photo books, and recap cards - Face ID lock, original-photo cleanup, and notification and widget options Keep the places you went, together.
