Track habits without the pressure How long has it been since you last watered the plants? Changed your car's oil? Called your parents? Or washed the bed sheets? Intervals is a beautifully simple elapsed-time tracker designed to help you keep tabs on the recurring tasks and habits in your daily life. Instead of counting down to a deadline, Intervals counts up—showing you exactly how many days, hours, and minutes have passed since you last completed an activity. Free your mind from trying to remember when you last did something. Just create a tracker, tap it when you finish the task, and let Intervals do the remembering for you. Perfect for Tracking: Home Maintenance: Changing water filters, washing bedding, deep cleaning rooms. Car Care: Oil changes, tire pressure checks, renewing registration. Health & Personal: Haircuts, replacing your toothbrush, taking medication. Pets: Flea and tick medication, grooming, vet visits. Habits: Tracking streaks, monitoring time between coffee breaks, or maintaining "inbox zero."
