Read full description

Write down ideas as memos, then arrange them like blocks to build your notes. PieceNote is a note app where you create pages by arranging memos. [ Arrange memos to create pages ] In PieceNote, you create pages inside a note, then arrange memos on each page like blocks. Use it for favorite places, study notes, ideas, work notes, reading records, and more. Instead of writing everything as one long document, you can split your content into separate memos and organize it by meaning or purpose. [ Collapse memos and keep pages tidy ] Memos can be collapsed whenever you need. Collapse basic information or extra notes that you don’t check often, and keep the memos you use most expanded. This helps you keep each page clean, easy to read, and organized. [ Write first, organize later ] When something comes to mind, just save it as a memo. You can reorder memos later, move them to another page, or combine multiple memos into one. Because each memo works as a small block of content, it is easy to organize the whole page afterward. [ Rich text for expressive writing ] When creating or editing memos, you can use formatting such as: - Bold - Italic - Underline - Strikethrough - Text color - Indentation - Bullet lists - Checkboxes - Heading sizes - Dividers [ Fully local and private ] Your data is stored on your device. PieceNote does not use an external server to store your notes. Backup, restore, and memo export are also supported, so you can move your data to a new device or keep important notes outside the app. [ PieceNote Premium (In-App Purchase) ] With PieceNote Premium, you get: - Completely ad-free experience - Dark mode - Color marker feature With color markers, you can add a visual marker to memos to make important memos or memos to check later easier to find. PieceNote Premium is a one-time purchase. No subscription required.
