X Calendar One X. Endless uses. X Calendar is a simple way to build consistency, keep track of everyday life, and create a visual history of the things you do. The idea is simple: create a calendar, tap a day, leave an X. Over time, those Xs tell a story. BUILD CONSISTENCY Use X Calendar to keep showing up for the things that matter to you. Create calendars for: • Gym • Reading • Running • Studying • No-spend days • 10,000 steps • Learning a new skill • Quit a habit • Anything you want to do more consistently Every time you do it, mark the day. Build the chain. Keep it going. OR SIMPLY TRACK LIFE Not everything needs to become a habit, goal or streak. Sometimes you just want to remember when something happened. Create calendars for things like: • Worked from the office • Watered the plants • Filled the car • Changed the bedding • Took medication • Called family • Played a sport • Anything else worth remembering One tap gives that day a place in your history. An X doesn’t have to mean good or bad. It simply means it happened. YOUR CALENDARS, YOUR WAY Create separate calendars for different parts of your life and keep the ones that matter most close at hand. Mark or unmark days in seconds, rename and organise your calendars, pin your favourites, and personalise how your marks appear. Prefer a different look? Switch your X to a tick or block.
