Pixel Done

Late June 2026 · initial version built in one day

My role: Product design, Vibe Coding development, distribution and ongoing maintenance

I built the first version of Pixel Done in a single day in late June 2026, taking a break from revision during final exam week. I was studying software engineering and curious about Android development, so this became a bold experiment in Vibe Coding. With GPT-5.5, I focused on improving how I develop with AI and exploring a new technology stack. I experienced the full mobile app lifecycle, from design and development to deployment and maintenance. I shared the app with classmates who use Android, then kept improving it based on their suggestions. Pixel Done centers on recording todos, with task and checklist editing, customizable Dock shortcuts, cloud backup and sync across devices.

Pixel Done todo overview showing tasks, completion states, priorities and times, with shortcut buttons at the bottom — Todo overview: record what needs doing and check each task’s completion state, priority and time.

Pixel Done task editor with a name field, priority control, reminder date and time, repeat options and a save button — Create or edit a task: set its name, priority, reminder time and repeat rule.

Pixel Done checklist creation view with existing checklists above and a list name field below — Create or edit a checklist: group todos into separate lists for different parts of life.

Pixel Done Dock settings showing a shortcut preview, plus button placement, available functions and ordering controls — Customize the Dock: choose shortcuts for sorting, deadline countdowns, hiding or clearing completed tasks, quick deletion and Markdown export, then arrange their positions and order.

Pixel Done cloud settings showing an account, an Error sync status, and language and theme options — Cloud backup and sync across devices: manage your account and sync from settings to save and continue your todos on different devices.
