Can I vibe code TickTick?

To-dos, calendar, habits, and a Pomodoro timer in one app.

🟢Yes — build itest. a weekend

TickTick is a competent to-do app with a habit tracker, a Pomodoro timer, and a calendar view bolted on. Each of those is individually a small, well-understood feature — a streak counter, a countdown, a month grid over your tasks. What TickTick sells is having them all in one synced app on every platform, not any single hard-to-build piece. For your own use you can assemble the same bundle in a weekend.

The one-shot prompt
Build me an all-in-one personal planner like TickTick. It needs four connected views over a single task database: a to-do list with projects, due dates, and priorities; a calendar view showing dated tasks on a month/week grid; a habit tracker with daily streaks and a completion heatmap; and a Pomodoro timer that can be started from any task and logs focused minutes back onto it. Add natural-language quick-add for dates and a Today dashboard that pulls from all four. Use Next.js App Router with a hosted Postgres, optimistic updates for snappy interactions, and keep each view a self-contained module. Deploy to Vercel.
Paste into Claude Code, Codex, or your agent of choice — then steer. Learn the moves in Prompt Engineering.
What you build

A unified planner with tasks, a calendar view, habit streaks, and a Pomodoro timer, all backed by one database.

What you give up
  • Polished native apps and widgets across iOS, Android, Mac, and Windows
  • Real-time sync you never have to think about
  • Smart date parsing and voice input
  • Collaboration and shared lists
Why people still pay

The whole pitch is one tidy, synced bundle on every device — rebuilding the features is easy, but matching that cross-platform reliability for $3 a month isn't worth most people's weekend.

Actually build it

A prompt is the first move, not the whole game. Course 01 teaches you to take a prompt like this one to a shipped, working app — reviewing, correcting, and steering the agent the whole way.
