About

Lykka

Lykka is a place for the good moments — and an app that hands them back to you later, when you need one. Save a line, a photo, or a voice note. Later Lykka returns one of those moments, with a short reflection drawn from your own life. It doesn't matter when it happened, only that it was good. A morning this week, a spring years ago. You keep the moments you'd otherwise lose, and Lykka does the remembering. When a saved moment is only a line, Lykka may ask one small question about it — "What did you talk about?" — never how it made you feel. Answer in your own words if you like, and the answer becomes part of the memory. One question, never a conversation. Your iPhone can lend a hand, too. With Apple's Journaling Suggestions, Lykka can show moments your phone noticed — suggested on your device, from your own library. Pick one, add a few words, and it's saved; photos you already keep are pointed out. Save a moment with Siri or a Shortcut, too — no need to open the app. What you save comes back to you. A memory returns each day, at a time you choose, on your home screen and in a quiet notification. On This Day brings back a moment from this same date in earlier years, when there is one. One waits on demand, whenever you tap "Give me a memory". And once a year, Year in Memories is a quiet look back across the moments you saved, closing with one reflection that reads across the whole year. When enough moments add up, Lykka may name a real pattern it sees across them — one honest observation about you, never flattery, never generic praise. The days that matter get their own place — a birthday, an anniversary, a day you remember someone by. Once a year, on the day, Lykka gathers the memories that belong to it. And now and then Lykka notices a quiet thread through your moments — a few times by the water — and gathers them into a small look back. Search understands what you mean, not only what you typed — “the trip when it rained” finds the right memory even if the word rain appears nowhere. Entirely on your iPhone. Letter to the Future lets you write forward, not only save the past. Seal a letter to your future self, or to someone you love, and attach a photo, a voice note, or a short video. It stays sealed until a date you choose, then arrives. It is sealed end-to-end — even Lykka can't read it. If you have started journals you never kept, Lykka asks nothing of you. There are no streaks, no scores, no daily guilt. You save a good moment when you have one, and it comes back on its own. Lykka doesn't write your entries for you, doesn't invent feelings you didn't have, and doesn't turn noticing into a game — what you keep is your own life, and that is enough. Your photos, recordings and words live on your iPhone. There is no account, no email, no password — nothing of yours becomes a profile, and nothing trains a model. To write a reflection or read a photo, Lykka briefly sends just that one memory to its servers to do the work, then keeps nothing. A memory you share with one person is sealed end-to-end and rewritten to read from their side — only someone with your link can open it, never us. A 12-word recovery code means your identity, your connections and your sealed letters survive a lost or replaced phone — still with no account and no email. Saving your moments and browsing your library are free, always. Lykka Plus is the part that brings them back: the daily return, the home screen widget, the on-demand memory, the per-memory reflections, and the observations that read across your moments. Built in Sweden. — — — Lykka Plus is a monthly or annual auto-renewing subscription; the annual plan includes a 7-day free trial. The exact price is shown in the app before you subscribe, and you can manage or cancel anytime in your iPhone Settings.
