Microsoft To Do supported devices and where you can use it
Microsoft To Do runs on iPhone and iPad, Android phones and tablets, Windows, and the web in a browser. If you sign in with the same Microsoft account on each one, your tasks sync across them. That makes it a practical choice if you want your lists to follow you from phone to PC and back again. The app is strongest on mobile and Windows, while the web version is useful when you need access from a browser or a shared computer.
What devices can run Microsoft To Do right now?
Microsoft To Do is available on iPhone, iPad, Android phones and tablets, Windows, and the web. That covers the most common personal and work setups, so you can usually use it on the phone in your pocket, the tablet in your bag, the laptop on your desk, or a browser at someone else’s computer.
On mobile, you install it from the Apple App Store or Google Play. On Windows, you use the app available for that platform. In a browser, you can use the web version without installing anything, which is handy if you only need quick access to your lists.
The important part is that Microsoft To Do is not limited to one device family. It is built to follow your Microsoft account across the platforms it supports, so you do not have to keep your tasks in separate places just because you switch between a phone and a PC.
Where Microsoft To Do works best
Microsoft To Do fits best on a phone when you want to capture something quickly. Say you remember a bill, a grocery item, or a follow-up while you are out. On iPhone or Android, you can add it right away, check it off later, and keep moving. That quick-entry use is where mobile feels most natural.
On a Windows laptop or desktop, the app is better for longer planning sessions. It is easier to review several lists at once, sort out work and personal tasks, and type longer task names or notes with a keyboard. If you keep To Do open while you work, it can sit alongside email, chat, or calendar apps without much friction.
The web version is most useful when you cannot install apps. For example, if you are using a shared office machine or a temporary computer, you can sign in through a browser and still get to your lists. That makes it a practical fallback, even if you prefer the installed app on your own devices.
The experience is broadly similar across supported platforms, but the web version can feel more limited than the installed apps. That matters most if you are used to working in a dedicated desktop app and want the same level of polish everywhere.
What people often assume is supported but isn’t
A common mistake is assuming Microsoft To Do works on every device that can run a Microsoft app. That is not the case. If a platform is not listed as supported, it is safer to assume To Do will not install there or will not give you the full experience you expect.
People also often expect support on older operating systems. If your phone, tablet, or PC is running an outdated version of iOS, iPadOS, Android, or Windows, the app store may not offer the current app, or the app may not run properly. The exact cutoff depends on the version you have, so the fastest check is whether the app store or device storefront lets you install it.
Another frequent assumption is smartwatch support. Microsoft To Do is not something you should expect to use directly on a smartwatch as a full app. If you see a watch notification or a reminder through another service, that is different from To Do being natively supported there.
Desktop platforms outside Windows can also trip people up. If you use macOS, Linux, or a Chromebook, the web version is usually the route to check first. That may be enough for basic use, but it is not the same as having a native app on every desktop operating system.
How your tasks sync across devices
Your tasks sync through the Microsoft account you use to sign in. If you add a task on your phone and then open the same account on your Windows PC or in the web app, the task should appear there after syncing finishes.
That only works cleanly if you use the same account everywhere. If one device is signed into a different Microsoft account, you may think sync is broken when the tasks are really sitting in another account. If you keep both a personal and work account, that mix-up is easy to make.
Sync also depends on connectivity. If a device is offline, changes usually stay on that device until it reconnects. Once it comes back online, the app can send and receive updates. That means a task you add while traveling may not show up on your laptop until both devices have had a chance to sync.
If something looks out of date, the first thing to check is the account, then the network connection, then whether the app has had time to refresh. In most cases, your lists are not tied to one device at all. They live with your Microsoft account and move with it across the supported apps and web version.
What to check before you install it
Start with the device itself. Check whether your phone, tablet, or computer is running a supported operating system version, because an older system is one of the most common reasons an app will not install or run well.
Next, look for the app in the right store or access point:
- iPhone and iPad: Apple App Store
- Android phones and tablets: Google Play
- Windows: the Windows app option for Microsoft To Do
- Other computers: the web version in a browser
If you are on a computer that is not Windows, the browser path is usually the quickest test. If the web version opens and you can sign in, you can usually use To Do without installing anything else.
Finally, make sure you are signing in with the Microsoft account you actually want to use for your tasks. That matters as much as device support, because the app can be installed correctly and still look empty if you opened the wrong account.
Conclusion
If your device is iPhone, iPad, Android, Windows, or a modern browser, Microsoft To Do is usually an easy fit. The safest next step is to try the store or the web version on the device you already use and sign in with the Microsoft account that holds your lists. If you use more than one device, confirm they all point to the same account so your tasks stay together.
Frequently Asked Questions

The web version is the practical option on a Mac. If you want the full app-style experience, Windows is the more direct supported desktop platform.

Will my tasks sync between my phone and my laptop?
Yes, as long as both devices are signed into the same Microsoft account and can connect to the internet. Changes on one device should appear on the other after sync.
