Overview

21Done came to Applore with a product idea rooted in behavioural science — a platform that guides users through structured 21-day journeys to build healthy, lasting habits. The premise was simple, but the execution needed to be anything but. Habit-building apps live or die by engagement, and keeping users motivated for 21 consecutive days requires more than a good concept. It requires thoughtful product design, smart notification systems, and an experience that feels personal every single day.

The problem

The structural limitations

Wellness and habit apps are one of the most crowded categories in consumer tech. Users download with the best intentions and abandon within a week.

  • 01

    Delivering structured, science-backed habit journeys that felt guided rather than generic

  • 02

    Serving content across multiple formats — wisdom, coaching tutorials, articles, coach challenges, podcasts — within one coherent flow

  • 03

    Building personalised nudges and reminders that were timed intelligently, not just scheduled

  • 04

    Ensuring a seamless experience across both mobile and web without any drop in quality

  • 05

    Supporting an international audience with multilingual readiness from day one

Approach

How we solved it.

A 21-day journey engine with progressive daily content (wisdom, tutorials, articles, challenges, podcasts), behaviour-triggered notifications, a marketplace, and cross-platform delivery.

Habit apps suffer high week-one drop-off. The product needed a behavioural-science-backed 21-day journey, cross-platform, and multilingual.

What we built

The layers that make the change stick.

Intelligence and engineering applied where they drive measurable change.

  1. 01

    Structured 21-Day Journey Engine

    A day-by-day journey module built on behavioural-science principles. Each journey is a progressive sequence of wisdom, coaching tutorials, articles, coach challenges, and podcasts — with the interface keeping users oriented to where they are on the 21-day arc.

  2. 02

    Behavioural Notification Engine

    Rather than generic reminders, an intelligent notification layer responds to individual user behaviour. Nudges are timed to reach users when engagement is most likely — reducing the friction that causes mid-journey drop-off.

  3. 03

    My Journeys Dashboard

    Users track active and completed journeys side-by-side. Visible progress creates accountability, and accountability is what keeps users going past day seven.

  4. 04

    Content Marketplace

    Beyond the primary journey, a marketplace module lets users discover and start new habits — extending the platform’s lifecycle well beyond a single 21-day cycle.

  • MultilingualArchitecture from day one
21Done now has a platform that does what most wellness apps fail to do — keep users coming back. We shaped how the product feels at every step of a user’s 21-day journey, made architecture decisions that keep the platform scalable, and delivered something the team could confidently take to market.
