Habitat - Group Accountability is a free iPhone app developed by Palmsonntag Inc. It falls under the category of Business & Productivity. This app aims to help users build new habits and achieve their goals by providing a platform for group accountability.

With Habitat, users can create habit and goal groups, which are called habitats. These habitats allow users to track their goals and habits alongside their friends. Users can create their own habitats or join the habitats created by their friends.

Inside a habitat, users can view the progress of their friends towards their individual goals and their current streak. Additionally, there is a group streak that increases only when everyone in the group completes their goals.

Habitat also offers a premium subscription for $2.99/month, which is optional. The subscription is auto-renewing and can be managed through the user's iTunes Store account settings.

Please note that the developer's terms of use and privacy policy can be found on the Habitat website.

Habitat - Group Accountability provides a supportive environment for users to track their habits and goals with friends, making it easier to stay motivated and accountable.
