TaskTowers: Habit Builder is a productivity app available on the iPhone platform. Developed by Fiacre Kabayiza, this app is designed to help users create and maintain good habits using the famous "Don't Break the Chain" productivity method and gameification techniques.

The app allows users to create habits, which are represented by towers that grow as the user maintains their daily habit streak. If a user misses a day, they have to rebuild their streak and tower. Users can also track their habit history, keeping a record of all their current and past streaks.

One of the unique features of TaskTowers is the leaderboard, where users can compete with friends and other users to see who can build the tallest tower. As users progress and build their towers, they also have the opportunity to unlock characters.

TaskTowers: Habit Builder offers a fun and engaging way to develop and maintain good habits, making it an ideal choice for individuals looking to achieve their long-term goals.
