Project Title: SubTrack – Your Subscription Command Center

What I Built

SubTrack is a mobile app concept designed to bring clarity and control to the chaos of modern subscription management. With the explosion of AI tools, SaaS products, and streaming services, most people have no idea what they're actually paying for every month — or when those charges hit. SubTrack solves that.

The app lets you log every subscription with full details: service name, plan tier, billing cycle (monthly, annual, weekly), start date, renewal date, cost, category, and personal notes. The home dashboard surfaces what's renewing soon and your total monthly spend at a glance. Tap into any subscription to see its full history, your notes on why you started it and how you're using it, and a direct link to cancel if needed. A categories view breaks down spending across buckets like Productivity, Health, Entertainment, and Personal. The next feature in the roadmap: free trial tracking with smart reminders before a trial converts to a paid charge.

How I Used Stitch

I started with a plain-language prompt describing the app concept and let Stitch stream the initial UI directly to the canvas. From there I used in-place AI edits to iterate on individual screens — refining the subscription detail view, adjusting the dashboard layout, and dialing in the category breakdown. What would normally take multiple back-and-forth handoffs between design and prototyping happened in a single session. Stitch's HTML-native canvas meant I could see realistic rendering of the interface — including the subscription card states — without leaving the tool.

Stitch Features Used

Streaming generations to canvas — the initial app UI materialized in real time from a prompt

In-place AI edits — iterated on individual screens with targeted prompts and point-and-click adjustments

Native HTML canvas rendering — saw accurate component states and card layouts as I built

Feedback on the Platform

Stitch made the ideation-to-prototype gap almost disappear. The streaming generation in particular changes how you think about exploring ideas — instead of waiting, you're reacting and steering in real time. The in-place edit workflow is intuitive enough that I didn't need to re-prompt from scratch every time I wanted a change. The biggest unlock for a workflow like this is that it lets you think visually and iteratively without switching tools. If Stitch deepens its component reuse and state management capabilities, it could genuinely replace a significant portion of early-stage product design work.
