You've had more good days than you remember.
Capture a good moment in seconds. It comes back to you weeks, months and years later, when you've forgotten it.
Capture your first momentFree. No ads. No data selling.
An independent project by a komoot co-founder. Free, no ads, built on positive psychology research.
Two steps are yours.
LifeSparks does the third.
1 · Notice something good
A trip, a dinner, an ordinary evening that turned out well. Anything you'd want to come back to.
2 · Hold on to it
However the moment is best held — a photo, a video, a few spoken words, a line of text. No prompts to answer, no form to fill in. One saved moment is one Spark.
3 · It finds you again, years later
Every few days, a Spark comes back — by email. Something you haven't thought about in a long time, at a moment you weren't expecting it.
Every three days by default, or as often as you like. Nothing repeats within a month.
Miss a week, miss a month — nothing breaks. There's no streak to lose.
Free. No ads.
Why this works
1 · The bias is real, and it's not a character flaw
Across a large body of research, negative information is processed more thoroughly and remembered more easily than positive information. This holds across cultures and ages. There's a reason for it: for most of human history, remembering what went wrong was the thing that kept you alive, and remembering a good afternoon was not. That instinct is still running, in a world that no longer rewards it and rarely lets it rest.
2 · Good memories don't come up on their own.
The bad ones don't need your help — something you got wrong years ago, still keeping you up. The good ones wait to be asked, and nothing in an ordinary day asks. LifeSparks does.
3 · Recall is the part that does the work
A song, a smell, a photo you weren't looking for — something sets it off and for a moment you're back there, feeling better than you did a minute ago. Research on positive memory finds that returning to a good moment reproduces a meaningful part of what you felt the first time.
What you end up with
The first Spark comes back within days. A small surprise — a photo you'd never have gone looking for, in the middle of an ordinary Tuesday.
After a few months, something else happens. You stop seeing single Sparks and start seeing the run of them — how many there are, and how many of them fall in years you'd have described as hard.
It's not a rosier picture of your life. It's a more accurate one, and an accurate one has more good in it than you'd have guessed.
Your life doesn't change. Your account of it does.
Most people have more to be proud of than they can call to mind. Seeing the whole of it — what you pulled off, the days you'd live again, and the people who were in them — makes it harder to sell yourself short.
I believe someone who can see their own life clearly stands steadier in front of what comes next. That's why I'm building it.

The elder branch started to sprout.
Recorded this on the walk home. Good day.
28th birthday. I don't remember this part.
Deichkind. Still not fully recovered.
Your phone already shows you memories. This is not that.
Your camera roll isn't a selection.
It holds everything — screenshots, receipts, the bad days, the good ones, all mixed together. Nothing in it knows which moments mattered to you. Only you know that, and it takes a minute to say so.
An album only works if you open it.
Journals, photo books, folders of favourites — all of them need you to remember, and to be in the mood. That's the part that doesn't happen.
LifeSparks needs both halves.
You choose the moment. It comes back on its own. Everything else has one or the other.
Why it's free, and what that means for your data
I'm not building a business here. There's no funding to return, no growth target, no exit — LifeSparks is a personal project that I pay for myself. Which means nothing about your moments has to be useful to anyone but you.
No ads. Not now, not ever. That's the wrong way to pay for something like this, and it's the one thing I won't do.
If you sign up now, LifeSparks stays free for you, with 10 GB of storage. Photos and videos cost real money to store, and if this ever grows beyond what I can pay for myself, new accounts may cost something. Yours won't.
Your Sparks are never sold, never analysed for advertising, and never used to train AI models.
You can export everything, any time, in a format you can actually read.
Delete your account and your data is gone. Not archived, not anonymised — deleted.
Your data is stored in the EU and covered by GDPR. The full details are in the privacy policy, which is written to be read.
Who's behind this
I'm Christoph. I grew up in Mittelberg, a village in Austria, studied physics in Munich, and co-founded komoot, which we sold in 2025. After a break, I found I still love building things — and this is a project I'm glad to be working on.
Some people keep a shoebox. Through the year they write down the good things as they happen, drop the notes in, and read the whole pile at the end of December. I came across that in 2008 and never quite let go of it — for years I turned over what a modern, more complete version would look like. Selling our company gave me the time to build it, and the means to run it for free.
If something here resonates, I'd be glad to hear about it.
Yours, Christoph
Questions
Is this just positive thinking?
No. LifeSparks doesn't ask you to reframe anything, look on the bright side, or pretend the hard parts didn't happen. It holds on to the good moments you chose yourself and gives them back later. The bad ones come back on their own anyway.
Can anyone else see my Sparks?
No. There's no sharing, no feed, no friends, no public profiles. Nobody sees your Sparks but you.
Where can I use it?
Right now LifeSparks runs in the browser, on any device. Apps for iOS and Android are coming at the end of the year.
What if you stop working on it?
I don't plan to. This is the long project for me, not a side experiment. And your Sparks are yours regardless: you can download all of them at any time, and if it ever did end, you'd have 90 days to take everything with you.
One good moment is enough to start.
