Keep what matters right where you can see it. Pinlet turns a short piece of text into a Live Activity, so it can stay visible on Dynamic Island and your Lock Screen while you move through your day. Add a deadline, a pickup code, a short intention, or anything else you do not want to lose in a list. PULL TEXT FROM ANY SCREENSHOT Circle any part of a screenshot or photo and Pinlet reads the text for you. Fine-tune the result word by word or character by character, then pin exactly what you need — no retyping. WRITE AND PIN Enter up to 120 characters and pin them in one tap. Update the text whenever the important thing changes, or unpin it when you are done. STAY VISIBLE On supported iPhone models, pinned text appears on Dynamic Island. It also appears as a Live Activity on the Lock Screen. iOS controls Live Activity availability and may end an activity according to system policy. START FROM ANYWHERE Long-press the Pinlet icon for Quick Input, or use Shortcuts to pin text, unpin, or open a screenshot in Pinlet from anywhere on your phone. RETURN TO WHAT MATTERED Pinlet keeps a history of successfully pinned text. Mark useful entries as favorites, reuse them as a new draft, delete individual entries, or automatically clean up older nonfavorite history. PRIVATE BY DEFAULT Your content and any text recognition happen on your iPhone by default. Pinlet has no account system, advertising, third-party analytics, or custom server. OPTIONAL ICLOUD SYNC If you choose to enable iCloud sync, your history, favorites, and recent activity times are stored in your private CloudKit database and synced to devices using the same Apple Account. iCloud sync is off by default. Requires iOS 17 or later. Pinlet is designed for iPhone.
