What keeps people on Things 3:Years of polish

Native Mac app

Plan ahead: Use Things 3 as inspiration, but give your app its own name, icons, and visual design.
Written by the checker for a first version. Paste it into Vibecode as is, or change it to make the app yours.
Build a native iPhone and iPad app for me to manage personal tasks with a calm, uncluttered design. The main screen should show Inbox, Today, and my named projects, with task titles and completion circles. Tapping a task opens its title, notes, due date, and project for editing. A clearly visible add button creates a task, and tapping its circle marks it complete. Let me create and rename projects. Today should show unfinished tasks due today or earlier. Save everything locally on the device. Use warm white backgrounds, dark text, soft blue accents, and generous spacing, with a sidebar on iPad. Include realistic sample tasks and projects so I can try every view.

Vibecode builds iPhone and iPad apps, but not a native Mac app.
Vibecode builds a first version from one prompt, and the checker would start with these parts: add, edit, and complete tasks saved on your device; switch between Inbox and Today using task due dates; organize tasks into named projects. Plan on an afternoon for a working first version with its real features.
Vibecode's first build is free for new accounts that sign up with Google or Apple on the web or the iPhone app, as the account's first project: one build of about 10 minutes with up to 3 features, on sample data. After that you need credits, from a paid plan or auto-reload. For your own version of Things 3, the checker lists these costs: Vibecode Plus ($20 a month); Apple Developer Program ($99 a year).
Things gives people a native Mac app alongside its mobile apps, Mac automation, and ongoing maintenance from Cultured Code. A version you build yourself won't have these: native Mac app; Mac Quick Entry with Autofill; cultured Code's maintenance team.
