Taby is a simple notes app for capturing ideas, tasks, reminders, thoughts and media in one calm place. Each note feels like a message to yourself: open a tab, write what is on your mind and continue with your day. Keep notes, lists, journal entries, links, photos and videos without building a complicated productivity system. The free version lets you create and organize up to 5 tabs and 10 tasks. Super Taby is an optional paid subscription required to unlock unlimited tabs and tasks, reminders, and color themes. Capture a thought before it disappears Some things need a full entry; others only need one line. Use Taby as an everyday notepad for a new idea, something you want to remember, a passing thought or a small detail from your day. Open the app, choose a tab and write naturally. There is no elaborate setup standing between you and the note you want to keep. Organize everything with tabs Create as many tabs as you need and give different parts of your life their own place. Keep projects separate from personal thoughts, save recommendations in a reading or watching tab, collect links for later, or make a space for recipes, travel ideas and memories. Tabs provide enough structure to find your way back without turning note-taking into another task. Add more than text A note can hold the context that makes it useful. Add photos and videos when words are not enough, keep links you do not want to lose, and combine text with the media connected to an idea or memory. Use Taby for visual journals, reference collections, inspiration, personal records or anything else that belongs beside your words. Make lists and remember what matters Turn everyday plans into practical checklists. Keep a to-do list, a shopping list, a set of steps for a project, books you want to read or movies you want to watch. Add reminders when a note needs your attention later. Check off completed items and keep the rest close to the notes and context that inspired them. See your notes from the Home Screen Widgets let you glance at important notes without first looking through the app. Keep a current list, a reminder or a thought where it is easy to notice during the day. Your notes remain part of your routine without asking you to maintain a complicated dashboard.

Simple notes, gentle structure and one calm place for everyday life. Requires iOS 26.0 or later.
