Our guides

The right app depends
on how you work.

A great Mac app can be useless on Windows. A brilliant personal planner can fall apart the moment you share a list. We tell you who each pick suits, what it costs and the reason you may hate it.

Quick answers

The questions we hear most often

Here is the short version. Each answer links to the longer review if you want the reasoning.

01

What is the best to-do app for most people?

Things 3 is our top September pick for personal planning on Apple devices. Todoist remains the safer recommendation when we do not know which devices you use or whether you need to share projects.

See the six-app shortlist
02

What is the best free to-do app?

If you use Apple devices, try Reminders before downloading anything else. Microsoft To Do makes more sense if your day already revolves around Outlook.

Compare free picks
03

Is Things 3 worth buying?

It is worth it if you plan alone, use only Apple devices and like its Today view. It is an immediate no if you need shared projects, Android or a browser app.

04

Which to-do app is best for ADHD?

There is no single ADHD pick. Tiimo is good for routines, Structured makes time easier to see, TickTick includes a focus timer and Todoist is very quick to capture into.

Find the right kind of help

Worth watching

Prefer to see the apps in motion?

Good video walkthroughs show things a screenshot cannot. We pick the ones that explain the app clearly and disclose their sources.

A common toss-up

Todoist
versus
TickTick

Todoist is cleaner and better for shared work. TickTick puts your calendar, habits and focus timer in the same app.

How we test

The real test starts after setup day

We look at capture, daily planning, recurring tasks, reliability, exports and price. More importantly, we see what happens after a missed day leaves the list in a mess.

See exactly how we test
  1. 01Open a new account

    We note the defaults and how much setup it demands.

  2. 02Add awkward tasks

    Recurrence, reminders, sharing, notes and search.

  3. 03Let a day go wrong

    Then we see how painful it is to recover.

  4. 04Check the details again

    Prices, platforms and important limitations.

Why the editor's background matters

Building apps changes what you notice.

Apple's App Store editors featured the developer's work and later published a founder profile. That does not make every verdict right. It gives readers a directly checkable record of the product experience behind these reviews.
