If life has started to feel like a blur, and you can barely remember the little details of your memories, Worlds gives you somewhere to keep them. Worlds takes a different approach to journaling and documenting your memories. Create private journals for yourself, or shared journals with the people you made those memories with — so you can write, add photos, and build a record of your memories together. Create a couples journal with your partner, a shared journal with your best friends or family, or keep one completely private to you. Each World becomes its own space for a different person, relationship or chapter of your life. Keep the little details that disappear with time — what happened, what made you laugh, and the ordinary days you'll wish you could remember years from now. SHARED WORLDS Create a private, invite-only World with your partner, friends or family. Everyone in the World can add their own memories, photos and perspective, so over time you're building something together — a record of the life you've shared. SOLO WORLDS Some memories are just yours. Create a private Solo World for the everyday moments, photos and memories you want to keep for yourself. KEEP MORE THAN THE PHOTO • Add photos and write the story behind them • Save memories to the date they happened • Browse your memories through the calendar • Search to find old memories again • Create separate Worlds for different people and parts of your life Worlds is free to use, with Premium available as an optional subscription. WORLDS PREMIUM Go Premium for: • Unlimited Worlds • Up to 20 photos per memory • Unlimited members in Worlds you own • Search to find memories faster • Custom World covers • Priority support Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
Memkeep
Read full descriptionHide full description
Memkeep is a shared diary for the people you love most. Some moments are too good to keep to yourself — and too personal to post on social media. Memkeep is a private, end-to-end encrypted memory book you build together with your partner, your closest friends, or your family. No followers. No ads. No algorithm. Just the two (or three, or four) of you. WHY MEMKEEP IS DIFFERENT • Truly private — every photo and word is end-to-end encrypted by default. Not a paid upsell. Not "encryption in transit." Real E2E. We can't read your memories. Nobody can but you and the people you invite. • Works offline, syncs later — built on a local-first architecture, so the app is fully usable on a plane, on a hike, or anywhere with no signal. Your entries sync automatically the moment you reconnect. • Built for two (or a few) — Memkeep is designed for couples and small friend groups. Create a shared space, invite your partner or your closest friends, and start writing. Family use is supported too. • No social media patterns — no likes, no follower counts, no public profiles, no algorithm deciding what you see. Just your shared timeline, in chronological order, the way memories actually happen. WHAT YOU CAN DO • Create a shared diary space and invite the people who matter • Write entries with text, photos, and dates • Comment and react on each other's memories • Browse a clean month-by-month timeline of your story • Keep a separate personal diary alongside your shared spaces • Use it on a flight, in the mountains, or anywhere offline PERFECT FOR • Couples — capture date nights, trips, anniversaries, and the small daily moments that make a relationship • Long-distance partners — stay close even when you're apart, with a private feed only you two can see • Close friend groups — document trips, inside jokes, and the years you spend together • Families — build a shared memory book across generations, without putting your kids on Instagram PRIVACY YOU CAN VERIFY Most "private" diary apps store your data in plain text on someone else's server. Memkeep doesn't. Your words and photos are encrypted on your device before they ever leave it. Even we, the developers, can't read them. Your shared diary belongs to you and the people you invited — nobody else. LOCAL-FIRST, BY DESIGN Memkeep is built on a modern local-first architecture (powered by Jazz CRDT). That means: instant writes, no spinners, no "trying to reconnect" errors, and a real app that keeps working when your signal doesn't. START TODAY Open Memkeep, create your first shared space in under a minute, and invite your favorite person. Build your story, one memory at a time. The little moments are the ones you'll want to remember in five years — Memkeep is where they go. Made with care for couples, friends, and families who believe their memories are theirs to keep. — — — Questions, feedback, or feature requests? We'd love to hear from you: hello@memkeep.app
