A habit tracker is a simple tool that records whether you followed through on a specific routine each day. The most basic version is a paper calendar with an X for every day you show up. Digital trackers like Expirel take that concept much further.
They send reminders when you forget, count your consecutive days as a streak, show weekly progress patterns, and reward you when you hit milestones. The result is a feedback loop that makes consistency feel tangible and achievable.
Research consistently shows that the act of tracking a behaviour significantly increases the chance of maintaining it. This is called the self-monitoring effect, and it works whether you are building a fitness routine, a journaling practice, or a household habit like checking food expiry dates.
Expirel is built entirely around this principle. Every feature streaks, reminders, weekly reports, badges exists to strengthen that feedback loop and carry you past the hardest stretch: the first 66 days.
