About X Calendar.

X Calendar is a simple visual tracker for iPhone—just like marking a big X on a physical wall calendar. Create a calendar for something you want to remember, then tap the day to leave an X. A habit, an event or the last time you did something: tracking, kept simple.

Gym days, reading, running, studying, office days, alcohol-free days, no-spend days, medication days, weigh-ins, watering plants, cleaning and changing bedding are all possible uses. Each mark records a date; you decide what it means.
