Start with Bullet. "I've tried close to 20 productivity apps. This is the one I've been looking for." - rcghaseler HOW IT WORKS Open Bullet, tap +, and capture whatever's on your mind. A task for later, a note to remember, an event coming up, a habit to build. Everything lives on one timeline - organized by day, week, month, or year. Schedule entries, set reminders, add sub-tasks, group things into collections, and tag across projects. It's as simple or structured as you need it to be. DAILY LOG, FUTURE LOG, MIGRATION Rapid logging. A Daily Log for today, Weekly and Monthly Logs for planning ahead, and a Future Log for someday. Migration. Collections. If you keep this system in a paper notebook, you'll feel at home in minutes. If you don't, you'll pick it up just as fast - it's simply a quick way to capture and organize your thoughts. Everything the paper system does, without the limitations. Search your entries. Sync across devices. Set reminders. Work offline.
