Think it. Say it. Keep it.

A lightweight note app for the thoughts that show up when your hands are full and your attention is somewhere else.

Brand film

The moment you think it, keep it.

From morning to night—at work, at school, on the court, and at home. See how Mark'n Memo catches the ideas that shape a day in this 38-second animation.

Includes English narration and on-screen captions. Press play to hear the audio.

How it works

From passing thought to useful note.

Mark'n Memo uses the speech recognition available on your Android device. It saves the transcribed text—not an audio recording—so your thought is ready to read, organize, and act on.

Capture

Speak a quick note or enter it with the keyboard.

Organize

Put the note in a category that makes sense to you.

Remember

Set a reminder when a note needs to come back at a specific time.

Everyday uses

Small notes. Real momentum.

On the go

Errands before they disappear

Capture the one thing you remembered halfway through your commute.

At work

Ideas between meetings

Save a sentence now, then shape it into a plan when you have time.

At home

Things worth coming back to

Keep recommendations, plans, and household reminders in their own categories.

Your way

A setup that feels familiar

Adjust language, theme, display mode, background, and memo date/time display. Turn on Dress-up mode to let Markun change with the seasons.

Designed with restraint

No account. No cloud full of your notes.

Your memo text, category names, and reminder content stay on your device and are not sent to a Masatiki-managed server. Firebase Analytics helps us understand app usage, but note content is not included in those events.

Planned advertising

Mark'n Memo currently does not display ads. To help keep the app available at no charge, we plan to introduce a banner ad at the bottom of the screen no earlier than April 2027. We will announce the timing and details again in the app and on this website before ads begin. We do not plan to use full-screen ads that interrupt note entry.

UPDATE 1.1.19

Add by voice. Swipe when done.

Add to saved memos by voice, or use the microphone when creating a memo inside a category. Swipe left or right to mark a finished memo complete, then restore one memo or all completed memos in the current list whenever needed.

Completing a memo cancels its alarm; restoring the memo does not restart the alarm. Clearer AM/PM time labels, past-time guidance, and immediate lock activation make everyday use easier.

Markun now keeps the outfit during voice input. Halloween starts October 10, Christmas starts December 4, and New Year runs January 1–14.

These instructions describe 1.1.19. Until it becomes available on Google Play, older versions may look or work differently.
