It demonstrates how solo creators can use AI to build meaningful tools that impact how people think about their lives.</p> <h2> What It Does </h2> <p>Life in Weeks visualizes a user’s life as a 105×52 grid where each square represents one week.</p> <p>Past weeks are shaded<br> The current week is highlighted<br> Future weeks are shown in a lighter color<br> Users can add life events (e.g. "Retirement at 65", "Child born in 2020")<br> A stats panel shows current age, weeks lived, weeks remaining, and upcoming milestones<br> The background subtly shifts through seasonal visuals based on regional climate<br> All data is saved in local storage; no login or accounts required<br> This creates a unique visual and emotional perspective on time that encourages users to live more intentionally.</p> <h2> How I Built It </h2> <p>This app was built entirely from a single master prompt, which defined the structure, components, styling, and UX requirements in detail.</p> <h2> Technologies </h2> <ul> <li>React 18 + TypeScript</li> <li>Tailwind CSS (no external UI libraries)</li> <li>Vite</li> <li>Lucide React (icons)</li> <li>localStorage (for data persistence)</li> </ul> <h2> Challenges </h2> <p>1 prompt</p> <h2> Accomplishments </h2> <p>Created an impactful, deeply reflective tool using one prompt<br> Engineered a performant, mobile-responsive experience<br> Designed for clarity, emotion, and future extensibility<br> Built a fully local app - no backend, no login, fully private</p> <h2> Try it out </h2> <p><a href="https://lifeinweeks-demo.netlify.app" rel="noopener noreferrer">https://lifeinweeks-demo.netlify.app</a></p> devchallenge wlhchallenge bolt ai Łukasz Modzelewski Wed, 23 Jul 2025 18:46:32 +0000 https://dev.to/lumo1987/todo-today-after-the-hack-1ggb https://dev.to/lumo1987/todo-today-after-the-hack-1ggb <p><em>This is a submission for the <a href="https://dev.to/challenges/wlh">World's Largest Hackathon Writing Challenge</a>: After the Hack.</em></p> <blockquote> <p>Part 1, about the project: <a href="https://dev.to/lumo1987/todo-today-one-prompt-challenge-406e">https://dev.to/lumo1987/todo-today-one-prompt-challenge-406e</a> </p> </blockquote> <h2> What I learned </h2> <p>Real productivity needs just enough structure to guide action, but not so much it becomes a chore.

Inspired by sprint planning, ToDo Today turns each day into a mission: prioritize, execute, and win. It’s built for clarity, not clutter.</p> <h2> What it does </h2> <p>ToDo Today is a web-based productivity app that guides users through daily sprint planning, helps them focus with a timer, build habits, track long-term goals, and review progress over time. Clean and intuitive, it’s built for people who want to do more — without doing too much.</p> <h2> How I built it </h2> <p>The app is a full web experience built with React 18, TypeScript, and Tailwind CSS. I defined clear models for Tasks, Goals, Sprints, Habits, and Settings. Features include a planning wizard, task execution view, recurring task logic, offline support via localStorage, and custom user preferences — all managed with React Context and useReducer.</p> <h2> Challenges I ran into </h2> <p>Designing the 3-step planning wizard while keeping it flexible and intuitive was tough. Managing recurring task logic, state syncing across sprints, and keeping the UI delightful without bloat also took iteration. Micro-interactions took time but made a big difference.</p> <h2> Accomplishments that I'm proud of </h2> <p>I built a full productivity system in one shot — from brain dump to focus mode, with sprints, habits, goals, stats, and a smooth UI. No filler. Just focused execution.</p> <h2> What I learned </h2> <p>Real productivity needs just enough structure to guide action, but not so much it becomes a chore. A system with goals, habits, and daily flow can be simple and powerful — especially with thoughtful UX.</p> <h2> Built With </h2> <p>bolt<br> netlify<br> react<br> tailwind<br> typescript</p> <h2> Try it out </h2> <p><a href="https://todotoday-1prompt-demo.netlify.app" rel="noopener noreferrer">https://todotoday-1prompt-demo.netlify.app</a></p> devchallenge wlhchallenge bolt ai
