iPhone Habit Tracker

lockdln

A habit tracker with enough structure to make showing up feel concrete.

Habit apps can become busy systems that compete with the behavior they are meant to support. lockdln keeps the loop deliberate: choose from 30-, 90-, and 365-day challenges, 75 Hard, or a custom challenge; add the habits that matter; then return for daily check-ins. Streaks and a consistency view make the commitment visible without adding a social feed or badges to collect.

Challenge
Turn intention into a visible daily commitment
Experience
Flexible challenges, daily check-ins, and streaks
Principle
Purposefully simple, with consistency kept in view
