About the Project

iLoma partnered with the 21 Days Challenge team to take a simple, powerful idea — build a habit in 21 days — from early concept through to a fully shipped, store-ready mobile app. The result is a lightweight, focused app that gets out of the user's way: onboarding takes under a minute, and the daily habit loop is a single tap.
