Notes app maker

Make your own notes app by describing it: folders, tags, checklists, search and a PIN lock. The AI agent builds it, you try it in the emulator preview and get the APK.

A notes app sounds simple until you try one that does not work the way you think. Here you describe the notes app you actually want, the AI agent writes a real Android app, you type your first notes in the emulator preview and download the APK. Keep the idea above or change the layout, the lock and the way notes are organized.

What your notes app will have

With the idea above, the agent builds these screens and wires them together:

  • Home — pinned notes on top, the rest in a two-column grid with each note's color, a preview of its text and the date it was last edited.
  • Editor — a title, a body with bold, bullet lists and tickable checklists, a color picker and tags, saved automatically as you type.
  • Search — one box that finds words in titles, note text and tags, with matches highlighted.
  • Folders — Work, Personal, Ideas or anything you name, plus an Archive for notes you want out of the way.
  • Trash — deleted notes stay for 30 days and can be restored with one tap.
  • Lock screen — a 4-digit PIN before anything is shown.

Features you can ask for

  • Photos in notes, taken with the camera or picked from the gallery on your phone.
  • A reminder on any note ("call the landlord, Friday 10 am") that fires as a notification even when the app is closed.
  • List view or grid view, sort by edited date, created date or title.
  • A Summarize button that turns a long note into five bullet points, using the AI backend that comes with the project.
  • Share a note as text to email or any messaging app.
  • A quick-capture screen that opens straight to a new blank note.
  • Sign-in and sync, so the same notes appear on your phone and a tablet.

Ideas to make it yours

The same maker builds very different notes apps. Try one of these:

Build a meeting notes app: each note has a date, attendees, decisions and action items. Action items from every meeting collect in one My tasks list with due dates, and a button summarizes a long note into five bullet points.
Build a notes app for a novelist: projects with chapters, a word count per chapter and per project, a daily writing goal with a streak, and a distraction-free mode with a large serif font and nothing else on the screen.
Build a class notes app for students: a notebook per subject, photos of the whiteboard attached to notes, three highlight colors, and a Revise button that turns a note into five flashcard questions.

Get it on your phone

  1. Press Build this notes app and sign in with Google.
  2. Write a few notes in the emulator preview, pin one, search for a word and delete one to check the trash.
  3. Ask for changes in plain words: "make the grid three columns on tablets", "add a yellow sticky-note theme", "open to a new note on launch".
  4. Press Download APK and install it on your Android phone after allowing installs from your browser once.
  5. For Google Play, build the signed APK and AAB from the same menu; the APK builder page explains signing.

Test with real notes, not "test 1, test 2". Paste in a shopping list, a long email and a recipe, and you will quickly see whether the preview text, the search and the colors work for you.

Tips for a notes app you will actually use

Speed matters more than features. The best notes apps open fast, put the cursor in a new note in one tap and never lose a word, so ask for autosave and a quick-capture button before anything fancy. Decide early whether notes live only on the phone or sync between devices: phone-only is private, works offline and needs no account, while sync needs a sign-in and the project's hosted backend. If privacy is your main worry, read where your data lives with an AI app builder before you choose. Finally, keep the design quiet. Notes are the content; a calm background, readable text and one accent color make an app you will still enjoy opening a year from now.

Frequently asked

Are my notes stored online?

Not in the default version. Notes are saved on the phone and the app works offline. If you want the same notes on two phones, ask for sign-in and the hosted backend that comes with the project, and notes sync through its online database.

Can I lock the notes app?

Yes. Ask for a PIN lock on the whole app or on single notes. The lock screen appears when the app opens and when you come back to it from another app.

Can I add photos to a note?

Yes. On your phone the app can take a photo with the camera or pick one from the gallery and attach it to a note, which is handy for whiteboards, receipts and handwritten pages.

Can AI summarize or tidy up my notes?

Yes. Ask for a Summarize or Make a checklist button. It uses the AI backend that comes with the project, so there is no AI account or API key to set up.

How do I install the notes app?

Press Download APK in the builder, open the file on your Android phone and allow installs from your browser once. For Google Play, build the signed version from the same menu.
