Description by Serhii Hryn Written by the developer, not by AppBrain. Click to read.
Brainee is a second brain and life organizer that works offline. Each project keeps its tasks, notes, events, files and links together, so a trip, a renovation or a side project lives in one place instead of five apps. Keep a private journal next to them. No account, no sign-up: your planner, notes and journal stay on your phone.

ONE PROJECT, FIVE KINDS OF CONTENT
★ Tasks: to-do list with priorities, due dates, nested subtasks and tags
★ Notes: rich-text notes with headings, lists, checklists and photos
★ Events: deadlines and appointments in a day, 3-day, week and month calendar
★ Files: photos and PDFs with previews, right inside the project
★ Links: save a web page or a map place and find it again
★ Link any item to any other: the task, the note that explains it, the PDF that proves it

ORGANIZE YOUR LIFE IN AREAS AND PROJECTS
★ Areas for the big parts of life: Work, Personal, Health, Travel, Home, Finance
★ Projects for the things you want to finish, each with a status and a progress ring
★ Project types that open with the right views: a Trip starts with itinerary, packing list and documents, a Journal with dated entries
★ Folders as deep as you need, and tags that cut across everything
★ Fits the PARA method: Projects, Areas and an Inbox for everything else

PLAN YOUR DAY AND YOUR WEEK
★ Upcoming: every dated task and event in one list, with filters by project, area and priority
★ Repeating tasks: daily, weekdays, weekly, monthly, yearly, or a few days after you last did it
★ Reminders at the time you choose, delivered even when you are offline
★ A daily planner for today and a project planner for the months ahead
★ 12-hour or 24-hour time, or your phone's setting

KEEP A PRIVATE JOURNAL
★ Write dated entries with the same text styles as notes, and backdate them to any day
★ Log your mood and add photos from the camera or your gallery
★ Keep a day streak and look back with a 6-month heatmap, a month calendar and mood bars
★ Scroll your entries as a timeline, or search them all
★ Entries stay on your device, like the rest of your Brainee data

CAPTURE NOW, SORT LATER
★ Inbox: drop in a thought, a task or a photo and file it when you are ready
★ Share links, photos and PDFs from any app straight into a project or the Inbox
★ Home screen shortcuts for a new task, note, event or photo

PRIVATE AND OFFLINE BY DESIGN
★ Everything is stored on your device: works on a plane, in the mountains, anywhere
★ No account and no cloud. Nothing to log in to
★ Dark and light themes, font scaling, English and Spanish

FREE AND PREMIUM
★ The free plan covers 3 areas and 5 projects with plenty of tasks, notes and events in each
★ Premium removes every count limit and raises the file size limit to 100 MB
★ Choose a subscription or a one-time lifetime unlock

WHO USES BRAINEE
★ People who found all-in-one workspaces too heavy and to-do list apps too thin
★ Second brain and PARA fans who want Areas, Projects and an Inbox on their phone
★ Trip planners, journal keepers, home renovators, job hunters, students and side-project builders

Your brain is for having ideas, not for holding them. Let Brainee be your second brain: one offline organizer for the tasks, notes and plans that matter.
