Forfeit: Habit Contracts is a hardcore commitment contract app available on the iPhone platform. Developed by Forfeit Inc, this app helps users stay accountable to their commitments by imposing financial penalties if they fail to complete their tasks. Inspired by the Habit Contract methodology explained in Atomic Habits, Forfeit is designed to motivate users to complete challenging habits that are difficult to self-motivate.

The premise of Forfeit is simple: users declare what they need to do, when they need to do it, and how much money they are willing to lose if they fail. Users are required to provide photo or time-lapse evidence within the specified time limit to prove their completion. If they fail to do so, the app will take their money. For example, a user may commit to hitting 30km on their Peloton before 8AM or forfeit $10.

In addition to its core features, Forfeit offers several other functionalities to enhance the user experience. Users can set the frequency of completing forfeits, track their averages to stay above a certain percentage, and even self-verify tasks if they choose not to submit evidence. The app also allows users to schedule recurring forfeits for up to 90 days on specific days of their choosing. Furthermore, Forfeit provides manual verification by its team, eliminating the need for an accountability buddy.

Since its launch in Summer 2022, Forfeit: Habit Contracts has gained popularity with users setting over 1000+ forfeits and staking more than $10k+. With its stringent commitment enforcement and additional features, this app aims to help users stay on track with their habits and achieve their goals.
