Comparison
Things 3ByDesign vs Things 3
Things keeps a beautiful list. ByDesign plans your year.
Things 3 is the to-do app Mac and iPhone people love: fast, calm and beautifully made. It also stops at the list, and at Apple devices. ByDesign puts your tasks on a calendar that syncs both ways, adds habits, goals, notes and a year canvas, builds the plan with AI, and runs on everything.
What you get with ByDesign that Things 3 doesnât offer
Your tasks on a real calendar
Tasks and events sync both ways with Google and Apple, Outlook connects too, and AI scheduling drafts your week on a preview you approve. Things shows Apple Calendar events read-only and has no built-in way to put a to-do on the calendar, by its own support guide.
AI that builds the plan
Say a goal and get tasks, subtasks, courses and deadlines, scheduled around your calendar, with an assistant you can talk to. Things has no assistant; its AI touchpoints are Siri AI in beta, Apple Writing Tools and Shortcuts.
Habits, goals, courses and time
A habit tracker with streaks and friends, goal pages with progress, Hub courses, Pomodoro and time tracking. Things has repeating to-dos and project progress pies.
Everywhere, with your team
Web, Mac, Windows, iOS, iPad and Android, with shared pages, assignments, chat and team plans. Things runs on Apple devices only and, per its support guide, does not support real-time sharing of to-dos or lists.

Why people switch from Things 3 to ByDesign
Tasks and calendar in one place
Connect Google, Apple and Outlook. Drag a task onto the calendar, or let AI schedule it, and the change shows up in your calendar app too. Edit it there and ByDesign updates.
Things 3: Things displays your Apple Calendar events beside your to-dos, read-only. Google and Outlook only appear if they sync into Apple Calendar first, and there is no built-in way to put a to-do on the calendar; a Shortcut can block time.

Say the goal. Get a scheduled plan.
Tell ByDesign what you want to achieve. It asks a few questions, then builds the tasks, subtasks, courses and deadlines and schedules them around the life you already have. Replan in one message.
Things 3: Things has no AI assistant or auto-scheduling. You set When dates and deadlines yourself; Siri AI (beta), Writing Tools and Shortcuts are its AI touchpoints.

Habits, goals and focus, built in
Track habits with streaks and stats, keep goal pages with progress, run a Pomodoro and track time on any task. Open ByDesign in the morning and it already works.
Things 3: Things has repeating to-dos, project progress pies and Markdown notes. There is no habit tracker, timer, time tracking or time estimate.

Every device, and the people you work with
ByDesign runs on the web, Mac, Windows, iOS, iPad and Android, so your plan is there on a work PC too. Share pages, assign tasks, @mention in comments and chat in the app.
Things 3: Things runs on Mac, iPhone, iPad, Apple Watch and Vision, with no Windows, Android or web version, and no sharing of lists with other people.

Donât take our word for it.
From Petey M.
I used to keep a calendar, a to-do list, and a project app. ByDesign replaced all of them. Itâs clean, it works, and I havenât needed anything else.
From Callio
Can I just say I love you. Finally, a good-looking app that isnât complex as hell. There are tears in my eyes. Iâll happily pay for this!đŻ
App Store Review
I have tried pretty much every calendar app and this one is the best Iâve tried.
