  • The Post-it® App is an application for your iOS® and Android™ devices that digitizes your handwritten square Post-it® Notes, seamlessly and easily. Simply capture handwritten Post-it® Notes with the camera or create new notes right on your device for those important reminders. Arrange, refine and organize notes and ideas on your boards anyway you see fit. Then share your organized boards with friends and co-workers, or export to your favorite applications and cloud services—including PowerPoint®, Excel®, PDF, Dropbox, iCloud (iOS® only) and plenty more.
  • A “Capture” is what we call the process of photographing multiple Post-it® Notes and then identifying each individual note so it can be recreated digitally.
  • A “Board” is the display area for captured Post-it® Notes. Multiple Captures can be included in the same Board. Additionally, the Post-it® Notes within a Board can individually be moved around, grouped and edited.
  • The Post-it® App works with all devices running iOS® 12 or above on Apple® Devices and Android™ version 7 or above on Android™ devices. It is optimized for iPhone® X and newer as well as for iPad Pro®.
  • Yes, the Post-it® App is available on Apple’s Mac® Platform for devices running macOS 10.15 Catalina or above. With iCloud Sync enabled your Post-it® Notes are automatically synced between your iPhone, iPad and Mac devices.

    If you are interested in a desktop app being added to other desktop operating systems, please drop us a line at postitapp@3m.com and let us know which operating system you prefer (e.g., Windows, web-based, other). If you are seeking to use the app with other screens larger than your smartphone, the app runs great on iPad®, Android™ Tablets, Chromebooks and can be projected to Apple TV® using AirPlay®.
  • Absolutely! Visit post-it.com/app to get all the latest information.

  • High contrast content captures best so we recommend using dark colored markers or felt tipped pens. The app also works great with Apple Pencil® and Samsung’s S Pen® for editing digital notes. The lighting in the room as well as the contrast between Post-it® Notes and the background also matters. Always capture in well-lit environments. If you have a light background such as a whiteboard, notes with stronger colors work best. If you have a dark background, lighter colored notes work better.
  • Currently the Post-it® App is optimized for square Post-it® Notes. If you use other shapes, the app may still capture them, but they will be displayed as a square. This may result in the content of that note looking squished. If you are interested in support for capturing non-square notes, please drop us a line at postitapp@3m.com.


  • 3M is not able to view any of the content you capture with the app.
  • The Post-it® App does not use or track any personal or user-identifiable data. To view the complete 3M privacy policy, visit 3m.com/privacy.
  • When you capture Post-it® Notes, you have the ability to tag the Capture with your location so that you can reference it later. If you give the app permission to access your location, the Capture view will show you where each capture was made. The location can also be seen when you export your Post-it® Notes as a PDF document, an Excel® spreadsheet or a PowerPoint® presentation. You can always change location permissions for the app through the Location Services on iOS® or App permission options on Android™, available in your device’s privacy settings.


  • For your boards to sync to other devices, make sure the following things are true:

    • You are logged in to iCloud using the same Apple ID on all of your devices
    • iCloud Drive is enabled in device Settings
    • iCloud is enabled for the Post-it® App in device Settings
    • iCloud Sync is enabled in the Post-it® App
    • You have internet access
    • You have available storage space on iCloud
  • If iCloud Sync is enabled on your Apple® devices, certain icons might appear to give you more information about your boards.

    • cloud icon The board has not yet been downloaded to your device. Tap the board to download it.
    • spinner icon The board is being downloaded to your device. Once downloaded you can view the notes in the Post-it® App.
    • cloud icon with exclamation point The board cannot be uploaded to iCloud. Make sure you have enough storage space available on iCloud.
    • exclamation point icon The board was updated on two different devices simultaneously and the changes are not in sync. Tap the board to pick which edits to keep.
  • The first time you run version 2.2 of the Post-it® App on iPhone or iPad, your boards will be converted to a new file format that supports iCloud Sync. Do not quit the app and leave your phone on while files are being converted. If you see a warning message in the app that your boards have not yet been converted, you can always tap to retry. One of the reasons why the Post-it® App may not be able to convert all your boards is that you do not have enough available storage on your device. Manage your storage in device Settings to make space available and then retry the conversion.
  • The first time you run version 2.2 of the Post-it® App on iPhone or iPad, your boards will be converted to a new file format that supports iCloud Sync. Do not quit the app and leave your phone on while files are being converted. If you get an error message that says your device does not have enough storage, you need to free up storage space on your device before you can continue with the conversion of your boards.
  • Tap will let you take a photo instantly with just a tap of the finger. Touch-and-Hold requires you to press and hold the camera button for 2 seconds to process your Capture. The touch-and-hold option improves capture stability and image quality.
  • Currently, the Post-it® App is optimized for square Post-it® Notes. If you use other types, the app may still capture them, but they will be displayed as a square. This may result in the content of that note looking squished, but don’t worry, all of the originally captured detail is still there.
  • Tap the + button and then the camera icon in the Post-it® App. The Capture Screen will open, activating the camera. Tap the landscape icon on the bottom right of the screen to access and select an existing photo on your device.
  • You may have the screen orientation locked on your device. Check your device’s settings to make sure it is turned off.
  • On iOS®, in the Board View swipe right to left. On Android™, in the Board View tap the menu icon on the top left. You will see your original Capture of the notes.
  • While the Post-it® App is optimized to capture square Post-it® Notes, it is possible to use the manual assist feature to capture additional content. With the original Capture View open, tap the content you wish to add. The Post-it® App will add a bounding box to the capture. You can drag the corners of the box to outline the content, then tap the Done icon to add it to the capture.
  • With your original Capture View open, simply tap any notes contained within the capture that are not outlined with a check mark in the image. When you return to your Board View, you will see your missing note added in a new group.
  • The Post-it® App’s ability to capture Post-it® Notes is dependent on the quality of your device’s camera — newer devices can capture more notes at the same time. All devices can capture at least 50 notes at once and oftentimes many more. Keep in mind that the more notes you capture at once the lower the resolution will be of each note.
  • We recommend keeping a minimum of 1/8 of an inch between notes. Overlapping notes may require manual assist to capture.
  • To help ensure quality and readability of note content, the Post-it® App will not take a photo if you are too far away from the notes you are trying to capture. The hints in the Camera View will guide you to move closer.
  • Try getting closer to the notes and making sure the camera is focused before capturing.
  • With the Post-it® App open, press the settings gear icon on the top of the screen. In the section Capture Hints, you will find the option to slide on or off the capture hints as well as the option to show or hide gridlines in the viewfinder. On iOS®, you will also see the option to enable or disable the app’s ability to prevent capture if the minimum conditions for a good capture are not being met.
  • Tap the + icon in the Post-it® App and pick the camera option to activate the capture view. You can either try to capture the whole wall in one image or capture portions of the wall in sections if you want higher resolution notes. After you have created a Board with the first capture, you can tap + again directly from the Board to add additional captures. You will notice that every capture is automatically put into its own group, making organizing easier.
  • Tap on an individual note to zoom. On iOS®, tap on the export icon then select "Save image". On Android™, pick one of the other export destinations to export a photo.
  • No. Importing pictures taken in panoramic mode is not supported at this time.

Digital Notes


  • No, you cannot un-combine boards. Once they are combined, you are unable to divide them.
  • With the Post-it® App open, create a new Board by capturing notes or open an existing Board containing notes. Simply drag and drop any of the notes in and out of groups to reorganize the notes as you see fit.
  • In the Board View, when you tap on a group of notes, you will see three layout options depicted as icons. The first shows the notes as you captured them. The second will organize your notes into rows and columns. The third on the far right aligns the notes to fit the aspect of the group shape you have selected.
  • Yes! Simply export your Board as one of the file types and open the exported file type to continue working with your notes in your favorite programs.
  • You have two options. In the Grid View, simply tap the Select button on the top right-hand side of the screen. Select all Boards you wish to combine and press the Combine button. Your selected Boards will be merged into one. On iOS®, you can also drag any of the Boards in the Grid View onto the Board you wish to combine. On Android™, you can press and hold on a board to select it, then select all other boards you wish to combine it with, and then tap on the Combine icon on the top right of the screen.
  • In the Grid View, simply tap on the Select button in the top right-hand side of the screen and then select the board you wish to delete. An icon of a trash can will appear. Tap that and select Delete Board.
  • Yes! On Android™ devices, you have the ability to “star” your most important notes. This will then place images of the starred notes in the Android™ home screen widget. This way, all you need to do is view your home screen to see your daily to-do’s, reminders or important thoughts. To star your notes, all you need to do is go into a Board, tap on an individual note, and tap the star icon in the lower right-hand corner. (Starred or favorited notes have temporarily been disabled on iOS® along with the “Today” screen widget. The feature will return in an upcoming release.)



  • To export a board, either select it in the Grid view and tap the Share button or enter the board and tap the Share button there. This will bring up the Export Board options where you will first select an export format and then an export destination such as email, iMessage®, AirDrop® to another device, Dropbox, Google Drive™, etc.
  • The Post-it® Board export format creates a “.postit” file which can be opened in the Post-it® App on another device. It can be used to send boards to other people, e.g. over email, iMessage®, text message, or using AirDrop® on iOS®. Post-it® Boards can also be synced across all your Apple® devices with iCloud. See “What is iCloud Sync” to learn more.
  • You can save copies of boards to cloud services such as Dropbox and Google Drive™, and import them into the app on another device. Boards can also be synced across all your Apple® devices with iCloud. See “What is iCloud Sync” to learn more.
  • With iCloud Sync you can keep notes and boards in sync across all your Apple® devices: iPhone, iPad and Mac (coming in October). This way a board you have captured on your iPhone will immediately be available on your iPad, and any change made on the iPad will sync right back to your other devices. In order to use iCloud Sync, you have to be logged in to iCloud using the same Apple ID on all of your devices. Make sure you have also enabled iCloud Sync in the Post-it® App.


  • You can enable and disable iCloud Sync in the Settings screen of the Post-it® App. With iCloud Sync enabled your notes and boards will be kept in sync across all your Apple® devices. If you disable iCloud Sync, changes to your notes and boards from that point onwards will only be stored locally on your device. You can change the iCloud Sync setting at any time in the Post-it® App.
  • In the settings view, tap on the “Default Note Color” section. A color menu will open, allowing you to select the default color for digital notes.
  • In the settings view, tap on “Siri® Shortcuts”. Within the Siri® Shortcuts menu, you can add Shortcuts to do the following: 1) Capture notes into a new board, 2) Create a note in a new board, 3) Capture notes into the latest board, 4) Create note in latest board, and 5) View last board. Simply hit the “+” sign then hit the red record button to record your new Siri® Shortcut.
