SingleHabit is a habit app built with the belief that changing every life habit at the same time is difficult, and it lowers your chances of overall, enduring success. Research (and, for many, lived experience!) shows that the most effective way to make sustainable, enduring changes is to focus on one thing, one habit at a time. SingleHabit helps you do just that. Make and track the new habits you want, one at a time, slowly over days, months, and ultimately years. The app only allows one active habit at a time, guaranteeing that you focus on just one thing. Once you've successfully implemented your habit, you can end it and create another one. The app allows you to measure and track streaks, set custom reminders, and view your daily, weekly, monthly, and annual progress as you go. Features of SingleHabit Pro: - Ability to focus on one habit at a time to maximize probability of enduring change - unlock badges for 3, 7, 15, 30, 60, and 100 day streaks - calendar views to track your progress over months and years - past habit library allows you to view all of your habits over the lifetime viewing the app - set custom reminder preferences SingleHabit aims to be the last habit app you ever need. Subscription Information SingleHabit offers Monthly and Annual plans that enable full access to all features and content. The app offers a 7-day free trial period, after which the subscription is auto-renewing unless turned off by the user.
