Maelstrom helps you stick to your routines and habits. Create routines by breaking them down into individual tasks with a duration. When you start a routine, the app will guide you through it one task at a time with a timer. When the time is up, it will alert you to move on to the next task to make sure you complete the routine. Additional features include: - Individual task schedules (e.g. "Journal every Sunday") - Minimum time for positive habits (e.g. "Read for at least 5 minutes") If this sounds helpful, give it a try. The app is free without subscriptions, ads or tracking. It is a personal project with no commercial intention.
