I've struggled with consistency for years.
You know the cycle: Get motivated. Download a habit tracker. Use it for three days. Miss a day. Feel like a failure. Delete the app. Repeat.
Last month, I decided to stop downloading and start building.
The Problem
Most habit apps are passive. They count your streaks but offer zero support when you're about to break. When an urge hits at 11 PM and willpower is gone, no amount of streak tracking helps.
I needed something that actively intervenes.
What I Built
Zenith Fortify — an AI-powered accountability companion that does three things differently:
One mission per day. Not fifty tasks. Not a scrolling list. Just one Prime Directive. Everything else fades into the background.
An Urge Crusher. When you're seconds away from breaking, you tap a button. A full-screen timer locks you in. Breathing exercises guide you back. By the time it ends, the urge has passed.
An AI coach that doesn't judge. Unlimited conversations. It remembers your triggers, understands your patterns, and gives practical advice — not generic motivation quotes.
The Tech Stack
I built this solo in about two weeks using:
React + Vite — Frontend framework
Supabase — Backend, auth, database (free tier handles 50,000 users)
Groq API — Powers the AI Coach (Llama 3.1 model, extremely fast and cheap)
Framer Motion — Animations
Tailwind CSS — Styling
Gumroad — Premium subscriptions with email verification
Vercel — Hosting (free)
vite-plugin-pwa — Makes it installable on phones as a PWA
Total monthly cost right now: $0. Groq gives generous free tokens, Supabase free tier is generous, and Vercel is free for static sites.
What I Learned
AI-assisted coding is insane. I used Cursor with Claude to generate boilerplate and debug. What would've taken months solo took weeks.
Supabase is a gift. Auth, database, real-time subscriptions, and row-level security — all in one place, all free to start.
Launch before you're ready. The app isn't perfect. Some edges are rough. But it works. And I'm getting real feedback from real users instead of polishing in isolation.
What's Next
Push notifications for daily check-in reminders
Native iOS/Android via Capacitor
Accountability partner matching
Content library (guided meditations, cold shower guides)
Try It Free
The app is completely free to use. I'm also giving away 20 free Premium slots to the Dev.to community:
FREE10MONTHLY — 1 month of Premium (10 available)
FREE10YEARLY — 1 year of Premium (10 available)
Use these at checkout on Gumroad, then enter your email in the app to activate.

Feedback Welcome
This is my first real project. I'd love honest feedback — bugs, feature ideas, design criticism, anything. What would make this truly useful for you?

The one-Prime-Directive constraint is doing more product work than the AI label here: reducing the daily choice set may be what makes the app usable at 11 PM, when a passive streak counter has no leverage. The Urge Crusher is a smart intervention loop-full-screen timer, breathing guidance, then a return to the task-and Supabase's auth and row-level security give a solo builder a credible foundation without spending weeks on plumbing. I'd instrument urge attempts, completions, and next-day return after a miss; the important tradeoff is helping users recover without turning another imperfect day into a new source of guilt.
This is the most insightful feedback I've received. You're right — the Prime Directive constraint does more heavy lifting than the AI. I'm now tracking urge attempts + next-day recovery as the next feature. The goal is to make imperfection feel like progress, not guilt. Thank you.
