Case study · Behavioral health mobile app

Support that shows up before the relapse.

NextStep is a recovery companion for people overcoming addiction. It watches for the high-risk moments — a mood dip, a skipped check-in, a 2 a.m. craving — and answers in real time with personalized coping tools, an AI companion that never sleeps, and one-tap access to people who can help.

01 · Problem

Relapse doesn't make an appointment.

Recovery support is real and it works — therapy, sponsors, group meetings. But it's scheduled, and cravings aren't. A craving typically peaks and passes within 15–20 minutes, and the most dangerous ones arrive when every scheduled form of help is closed. Here's the night the whole product is designed around:

21:40

A hard day ends badly

Work stress, an argument, exhaustion. Mood is low — but on paper, tonight looks like every other night. Nobody's watching the pattern forming.

23:05

Risk builds quietly

Sleep won't come. An old contact texts. The check-in reminder gets swiped away. Every signal exists — scattered across apps, visible to no one.

01:50

The craving peaks

The therapist is asleep. The Tuesday group is five days away. The sponsor's phone might ring through. The options collapse to willpower — and shame makes even dialing feel heavier than the craving itself.

02:10

Won or lost, silently

Twenty minutes later it's over, one way or the other — and no one else ever knew it happened. This is the moment NextStep is built for.

02 · Research

Four findings became four rules.

I read relapse-prevention literature (cravings as short, survivable waves; triggers as patterns), studied how recovery communities actually support each other, and mapped the craving-to-calm journey minute by minute. Everything the prototype does traces back to one of these rules.

/01
Meet the moment

Help is one tap, from anywhere

A persistent SOS button and Call Help action live on every screen. In a spiraling moment nobody navigates menus — the path from panic to a human voice or a grounding exercise is a single thumb-tap.

/02
Risk-aware, not just tracking

The app notices before the user asks

Mood check-ins feed a live risk score. When it climbs, the home screen quietly reorders itself — a 5-minute breathing exercise surfaces first, not a settings menu. Support arrives proactively, matched to the moment.

/03
Progress you can feel

342 days, made visible

The sobriety ring, streaks, milestones and a timeline turn abstinence into identity. On a bad day, the strongest counter-argument to "one won't hurt" is watching what you'd be resetting.

/04
Never alone, never exposed

Community and AI, privacy first

An AI companion with a personality you choose, plus an anonymous peer community. Stigma is the adoption barrier — so anonymous mode, biometric lock and end-to-end encryption are defaults, not options buried in settings.

03 · Prototype

One app for the good days and the hard ones.

These are live renders of the actual working prototype — four different screens of the same app. The risk-aware home dashboard, the AI companion chat, the journey view that makes progress tangible, and the anonymous community.

Launch it in a new tab and walk the full flow yourself — splash, sign-in, mood check-ins, profile and the SOS path.

04 · Result

Built to win a 15-minute battle.

Every design decision is aimed at the same short window — the minutes when a craving peaks. Against the baseline of scheduled-only support, the concept closes the gap between the moment of risk and the moment of help.
