Best Simple Todo Apps in 2026

The productivity app market is overwhelming. There are hundreds of options, many of them packed with features you'll never use. If you just want a simple way to manage tasks without a PhD in project management, this guide is for you.

Here are the best simple todo apps in 2026 — ranked by how quickly you can go from "I need to do this" to actually doing it.

What Makes a Todo App "Simple"?

We looked for apps that:

• Take less than 5 minutes to set up
• Don't require watching tutorials
• Focus on task management, not project management
• Have clean, uncluttered interfaces
• Get out of your way so you can work

The Best Simple Todo Apps

1. Skedio

Best for: People who want tasks in Google Calendar automatically

• Price: Free / $2.99 per month
• Key feature: Automatic Google Calendar sync with time blocking
• Setup time: Under 2 minutes
• Why it's simple: Add a task, it appears in your calendar. That's the whole workflow.

Skedio focuses on one thing: bridging your todo list and your calendar. There are no project hierarchies, no automation rules, no AI trying to plan your day. You add tasks, set durations, and Skedio schedules them in your Google Calendar.

2. Google Tasks

Best for: People who want something free and built into Gmail

• Price: Free
• Key feature: Native Google integration
• Setup time: Zero — it's already in your Google account
• Why it's simple: It's a checklist inside Gmail and Google Calendar.

The catch: tasks don't block time in your calendar. It's purely a list with optional due dates.

3. Apple Reminders

Best for: Apple ecosystem users who want a free, native app

• Price: Free
• Key feature: Siri integration and location-based reminders
• Setup time: Zero — pre-installed on Apple devices
• Why it's simple: Clean interface, just lists and reminders.

The catch: Apple-only. No web version, no Windows, no Android. No Google Calendar sync.

4. Microsoft To Do

Best for: People in the Microsoft ecosystem

• Price: Free
• Key feature: Outlook and Teams integration
• Setup time: 2 minutes
• Why it's simple: My Day view gives you a focused daily list.

The catch: No Google Calendar sync. Best experience requires Microsoft 365.

5. Todoist

Best for: People who want a simple app that can grow with them

• Price: Free / $4-5 per month
• Key feature: Natural language input and project organization
• Setup time: 3-5 minutes
• Why it's simple: Clean interface with powerful features when you need them.

The catch: Can become complex as you add projects, labels, and filters. Calendar sync is manual.

How to Choose

Ask yourself these questions:

• Do you use Google Calendar? If yes, look at Skedio or Google Tasks.
• Are you Apple-only? Apple Reminders is free and built in.
• Do you use Outlook? Microsoft To Do integrates seamlessly.
• Do you need project organization? Todoist scales well.
• Do you want time blocking? Skedio is the only one that does this automatically.

The Bottom Line

The best todo app is the one you actually use. Start with the simplest option that fits your workflow. You can always switch later — but you can't get back the time spent configuring a tool you'll abandon in a month.
