Can AI replace Things 3?

The core loop is small enough for a capable coding agent to produce a useful local version in one sitting. For Things 3, build a polished personal task manager with areas, projects, tags, deadlines, and a today view. The hard boundary is exceptional native design, apple-device sync, shortcuts, and long-term maintenance, plus cross-device reliability and workflow polish.

Replacing a paid app means you set it up and keep it running: hosting, updates and backups can be on you. What you give up.

01What it costs

Price variesMac license, one-time

Checked Aug 14, 2026 · source: culturedcode.com.

PlanMonthlyBilled yearlyWhat you get
Things for Mac——1 Mac App Store license; 15-day direct-download trial.
Things for iPhone & Apple Watch——1 iPhone/Apple Watch App Store purchase.
Things for iPad——1 iPad App Store purchase.
Things for Apple Vision——1 Apple Vision App Store purchase.

Hidden costs: Mac, iPhone/Watch, iPad, and Vision are separate purchases; there is no cross-platform bundle, though Things Cloud sync is free.

02Could AI build it for you?

The core job: Capture tasks into areas and projects with tags and deadlines, schedule or repeat them, work from a focused today view, and keep history locally.

What a working version needs:

  • macOS, Windows, or Linux
  • notification permission
  • local SQLite database

Editorial comparison targets the Mac license plan and a personal desktop task manager DIY substitute. Recheck price before merge.

03What you'd give up

  • exceptional native design, Apple-device sync, shortcuts, and long-term maintenance
  • perfect mobile sync
  • calendar and email integrations
  • shared workspaces
  • behavioral coaching polish

People still pay for Things 3 because task software is sticky because trust, speed, and ubiquitous capture matter more than the database schema. The recurring cost buys recurrence edge cases, notifications, sync conflicts, calendar APIs, mobile capture, and backups, not just the visible interface.

Super Productivityopen-source

A local task manager with timeboxing, Pomodoro, and no account begging to be created

Vikunjaopen-source

A capable Todoist replacement once you accept becoming its hosting department

Versus paying: Vikunja feels like a hosted web task system and cannot match Things’ native offline polish, frictionless capture, or elegant Today and Upcoming experience.
