Most people spend four months deliberating over a business idea. Evan spent four months building one — and by the end of it, his gamified habit-tracking app was generating $14,000 every month. No paid ads. No outside funding. No team.

The Product: Making Habits Actually Stick

Locked isn’t just another habit tracker with a streak counter and a pastel colour scheme. It’s a gamified experience designed to tap into the same psychological mechanics that make video games compulsive — applied to building personal discipline.

Users earn XP for completing habits. Badges mark milestones. Leaderboards inject competition. Character selection adds personalisation. The result is a habit app users actually want to open — not out of guilt, but because it’s genuinely engaging.

The build took approximately six weeks. Evan used Figma for design and Claude Code for development — essentially a solo operation. The tech stack was rounded out with Superwall for paywall A/B testing and Supabase as the database backbone.

The Growth Engine: Organic Content and the Influencer Playbook

Evan is emphatic: Locked did not grow through paid advertising. Every dollar of revenue came through organic short-form content and strategically structured influencer partnerships.

Paid ads buy attention. Influencer content borrows trust. For a habit app targeting productivity-oriented, self-improvement audiences — the kind who follow creators talking about “staying locked in” — trusted voices are exponentially more valuable than ad units.

The Five-Step Influencer System

Evan runs a repeatable process, not a scatter-shot outreach campaign:

1. Identify niche creators. Target productivity, self-improvement, and “locked in” lifestyle content creators with genuinely engaged audiences.

2. Reach out via DM. His opener is deliberately minimal — “paid promo?” — low friction, easy to answer.

3. Get on a call. Move fast off DMs. A call builds rapport and ensures authentic promotion rather than a stiff ad read.

4. Structure a profitable deal. The key mechanism: a minimum view clause. Tying compensation to a view threshold keeps CPM low and transfers performance risk away from flat upfront fees.

5. Launch with a 15-second rule. The app must appear within the first 15 seconds of the content. Audiences drop off fast — integration happens before attention does.

The Tech Stack

  • Figma — UI/UX design and product visual language
  • Claude Code — Primary development tool (claude.ai)
  • Superwall — Paywall logic and A/B testing
  • Supabase — Scalable open-source database

Together, these tools represent a fundamental shift: a motivated solo founder can now build what once required a small engineering team.

The Bigger Advice: Start Sooner Than You Think

Evan’s sharpest commentary isn’t about tech stacks or growth tactics — it’s about the conventional path. His view is direct: for entrepreneurially minded young people, following the standard school-degree-job script uncritically means surrendering years of compounding experience.

Starting early is an asymmetric bet. The downside is bounded. The upside — in learning, in building, in the possibility of something like Locked — is not.

It’s advice that’s hard to dismiss when the person giving it is four months into a $14,000/month revenue stream.

What Locked Actually Proves

Evan’s story isn’t really about habit tracking. It’s about what becomes possible when a genuinely engaging product meets a disciplined, system-driven growth approach.

Four months. Fourteen thousand dollars a month. And by all indications — just getting started.
