a still, handwritten almanac — for iphone
every person becomes a star in a night sky that is yours alone. tap one, and the moment comes back — where you met, what you spoke of, the small details that fade.
private, and quietly yours 
three quiet steps to remember the names and faces of the people you meet — and keep them from fading after the moment passes.
add someone while the moment is fresh — a name, where you met, what you spoke about. a small companion mascot and a handwritten label appear in your sky.
each star holds dated notes, photos, and quick sketches. tap it, and the moment comes back — not just the fact of it.
hand your phone over. a guided sketching view lets them draw a mark on their own star — a guestbook page in your sky, and they see nothing else.
short, honest guides on keeping a people journal — from remembering names to writing down a conversation before it fades. read them all →
that is exactly what memento.sky is. every person you meet becomes a star in a private night sky — tap it and the moment comes back: where you met, what you talked about, the small details that fade. learn more →
mostly attention: during an introduction you are composing what to say next, so the name never gets encoded. and whatever does get encoded fades within days unless you return to it — which is why writing a person down while the moment is fresh works better than any trick. learn more →
capture two or three lines soon after — where you were, what you talked about, one detail worth keeping. rereading them later returns the whole moment, not just the fact of it. learn more →
a centuries-old practice of copying the passages and encounters worth keeping into one personal volume. memento.sky is a commonplace book whose subject is people — a still, handwritten almanac. learn more →
there is no account to create. your sky lives on your iphone and syncs through your own private icloud — we run no servers and cannot read your journal. usage analytics are pseudonymous, with no name, email, or precise location, and nothing is ever sold. learn more →
your sky is stored on your device, so it works without a connection. with icloud signed in, deleting the app leaves your sky safe in your own icloud; without icloud, deleting the app clears the sky. learn more →
no — memento.sky is built for iphone (ios 26 and later), and there is currently no android or web version.
yes. export your whole sky as a zip whenever you like, or delete it all in one step. it is your journal, not ours. learn more →
your sky starts clear tonight.
the first star is someone you have already met — you just have not spotted them yet.
not a network, not a contact list
