A science-backed habit builder designed to help habits actually stick.

It’s the start of a new year—and with it, countless new resolutions. Many people aim to improve their lives by building healthy and productive habits, yet most fail due to lack of support, motivation, or sustainable design.

We built Loop to change that.

Instead of simply tracking habits, Loop uses scientifically backed behavior-change principles to maximize the chances that users successfully build and maintain their desired habits.

Loop is a habit-building app that goes beyond traditional trackers by actively supporting users through behavioral science.

In addition to core habit features such as goal setting and progress tracking, Loop introduces three key science-driven mechanisms:

Each habit can be linked to an accountability person.

• Automatic SMS updates are sent based on habit performance
• People are significantly more likely to follow through when they don’t want to disappoint others
• Grounded in Social Contract Theory

Users log their mood each day, and Gemini-powered AI dynamically adjusts habit goals.

• Lower effort goals on low-energy days
• Higher targets when users feel capable
• Reduces friction to getting started

Based on Activation Energy Theory, which shows people are more likely to act when effort is minimized.

Users can build a maximum of 3 habits at a time.

• Willpower is a limited resource
• Fewer simultaneous habits increase success rates

This decision is informed by Cognitive Load Theory.

Loop also supports group habit building.

• A habit is only completed if everyone completes it for the day
• Encourages real-world accountability
