A card a day.In 10 years,
a memoir.

Each day's card adds up — into a book you'll open again someday.

The screen is simple.What's behind it isn't.

The place you named yourself, your people, the temperature at that moment — a whole day lives behind one card.

Today's Color
Day Card

One photo, one color, one line.
That's how a day stays.

Open the app and today is already there — a photo, the day's mood on it, one line beside it.

The day's mood seeps into the photo

At the end of the day, pick today's color. It doesn't sit in a dot. It seeps into the photo and becomes the air of that day.

One line for the day

It can be anything. A thought out of nowhere, a line you never let go of, words that only mean something to you that day.

Time at your fingertips

Swipe sideways and yesterday arrives. Then the day before. One swipe, one day.

How mo.Days flows

  1. Capture the moment

    Keep it, no pressure

  2. Complete the day

    Sort it out when you're free

  3. A life, recorded

    Open it again, anytime

Moments

Everything stays, down to the temperature.

An entry holds more than words and photos. What time it was, where you were, who was with you, what the air felt like — it all stays together.

  • WeatherFrozen as it wasOpen an entry three years from now and that spot is still 25°F.
  • PlaceKept by the name you call itNot “Coffee Co. #3” — “that window seat.”
  • PeopleWho you met, who you thought ofYou can add someone who wasn't there but came to mind.
  • Late nightPast midnightLeave the time at 1 a.m. and let the entry belong to yesterday.
Reading a day in full — each entry carries its time, place, and weather
Clips and Quick Clips

Throw it down now.
Finish it later.

The moments worth keeping arrive when your hands are full. So you drop a fragment and come back later.

A fragment stays a fragment

One line is enough. So is one photo. So is nothing but where you're standing.

No need to open the app

One button on the Lock Screen saves it without unlocking your phone. Put it on the Action button, or just ask out loud.

Scattered pieces become a journey

Drop one at every stop and tie them together later. The hours and distance between them surface on their own.

Wrapping Up the Day

Answer a few questions, and the day is done.

Every evening it asks once: how was today? On nights you've already wrapped up, it doesn't call.

  1. The wrap-up card at the top of the timeline

    Just answer what it asks

    It goes in order and skips what doesn't apply.

  2. The step where you pick today's color

    One color is enough

    On a day you wrote nothing, one color is a complete day.

  3. The last step — a preview of the day's card

    Today's face, at the end

    The day's card appears at the end. See how today will stay, then close.

Closing isn't final. Change your mind later and tap that day's closed-book button to open it again. A few days ago or years ago, it works the same.

Photo Pick

No digging through thousands. Your best photo finds itself.

Two photos, side by side. Pick the one you lean toward. That's it — it runs like a tournament bracket.

  1. Day
  2. Week
  3. Month
  4. Year
  5. Lifetime

All you did was choose between two.

The choosing becomes part of the story

Pick differently later, and your past picks still stay.

Can't decide? You don't have to.

Some pairs can't be called. Leave them open and come back anytime.

Finding and Gathering

Find it without knowing when.

What you remember is rarely the date. It's who was there, where you were, what you talked about.

PeoplePlacesTagsPhotosDates

By anything but the date

Stack conditions to narrow it down. It searches your words, tags, names, places, and every day's line.

Gather by person

Press and hold a name while reading, and every day that person appears in gathers in one place.

Name a stretch of time, later

Pull up five years of “commute,” then name all of it “The A Corp Years” at once.

Entries gathered by one person
Keeping Things Secret

Nothing shows that anything is hidden.

A locked folder is already a confession.

There's nothing more to show you.
Your entries would say the same.

Not locked. Just not there.

Private entries don't get a padlock. They're simply not there.

When someone asks to look

Give them a different passcode. The app opens perfectly with it. Only what you keep private is missing.

When there's no time to type

One gesture you set switches over on the spot.

Off means it doesn't exist

If you don't use it, the word “hidden” appears nowhere in the app.

Archive

Not deleted. Just set aside.

Not wanting to see something and wanting it gone are different things.

It just steps aside

Put an entry in the archive and it leaves the timeline, search, and Photo Pick. One more answer for the things you almost deleted.

Bring it back anytime

Take it out and it returns exactly where it was.

Not the same as hiding

It isn't for keeping things from others. It's a place for what you don't want in view right now.

Week, Month, and Life Views

Ten years from now, your memoir is already written.

A day is a page. A month is a chapter. A year is a volume.

  1. Day — today's screen
    Day
  2. Week — Week View
    Week
  3. Month — Month View
    Month
  4. Decade — Life View
    Decade

From a day to a decade

The further down, the closer to a day. The further up, the closer to a life.

Words from that season

Newlywed. Exam year. Words that belonged to one stretch of time turn out to be its name.

Not a highlight reel

No algorithm picked these. The colors, photos, and lines are the ones you chose. You're the editor, start to finish.

And more

When the phone changes

It carries over through iCloud, original photos included. Open a new phone and it's all there.

Your own backups, too

Restoring brings back only what went missing. Nothing you wrote in between is overwritten.

If you use mo.Today

The to-dos you finished and the routines you kept are already waiting in the evening wrap-up. Just pick what to keep.
