Microsoft To Do vs. Structured
Microsoft To Do is published by Microsoft Corporation and has been on the App Store since 2017-04-19. Structured is published by unorderly GmbH and has been available since 2020-04-09. Both are free to download, and that is where the resemblance ends. Microsoft publishes no paid tier for To Do at all — it states the app is free with a personal Microsoft Account, and what it asks for instead is an account of a supported type, from a list with real exclusions on it. Structured names no account requirement anywhere in its published material, and asks for money instead: a subscription or a one-time purchase that unlocks a defined set of features. This comparison is built from what each developer publishes — App Store listings, Microsoft’s supported-accounts and sync documentation, and Structured’s own help centre — with every claim sourced and anything unverifiable listed as such.
Everything below comes from published sources, checked on 2026-08-24 and linked in each section. Where the sources don’t answer a question, it’s listed under What we couldn’t verify rather than guessed at.
Microsoft To Do
A free task manager tied to a Microsoft account, storing tasks on Exchange Online and syncing to Outlook Tasks.
Structured
A day planner built on a drag-and-drop timeline, free to use, with a Pro tier sold monthly, yearly or once.
The two put their cost in different places. Microsoft To Do never asks for money, and asks instead that your account be one of the types Microsoft supports — a list with genuine exclusions on it. Structured asks for nothing but money, and only for part of the app. Which of those is the cheaper deal depends entirely on which account you already hold.

Where each one fits
Microsoft To Do costs nothing and has no paid tier anywhere in Microsoft’s published material, so there is no upgrade to reach and no feature held back for one. It stores tasks on Exchange Online and syncs them to Outlook Tasks, which makes it the obvious choice for anyone whose mail already lives there, and its listing covers Apple Watch as well as iPhone and iPad. The cost is eligibility rather than money. Microsoft publishes a list of account types it does not yet support — on-premises Exchange Server, most governmental accounts, Microsoft 365 Apps for enterprise, and the T-Mobile and 21Vianet-operated variants — and if the account you would use is on that list, the price is beside the point. It also requires iOS 17.6, a higher floor than any other app in this category on this site.
Structured asks nothing about your account and something about your wallet. Its free tier holds the part of the app that defines it — the timeline itself, with tasks, subtasks, notes, notifications, widgets and schedule sync — so it is genuinely usable without paying, and Pro can be bought once at US$99.99 rather than rented indefinitely, which few apps in this category offer. Against that, the features most people reach for in the second week are the paid ones. Calendar Import, Reminders Import, Recurring Tasks and Structured AI all sit behind Pro, which means anyone intending to feed Structured from their existing calendar or from Apple Reminders is buying Pro in order to do it. A free timeline you must retype into every morning is a different product from the one the listing describes.
That shape — a free plan that holds the core and charges for the parts you reach for second — is the same one Todoist vs. TickTick turns on, and what Todoist costs sets out where Todoist draws its own version of the line, with recurring and custom reminders on the paid side of it.
What we couldn’t verify
These are questions the published sources do not answer. They are listed here unresolved rather than guessed at.
- What Structured Pro costs on the App Store. Its listing shows Structured Pro (Monthly) at both $2.99 and $6.99 and Structured Pro (Yearly) at both $9.99 and $29.99, while Structured’s help centre names US$6.99, US$29.99 and US$99.99 only. Nothing published explains the extra figures, and none of them is treated as superseding the help centre here
- What Structured’s Android-only Weekly tier costs, which its help centre names as a tier without giving a figure
- Whether Microsoft To Do can be opened and used at all without signing in. Microsoft documents which accounts are supported but does not address the no-account case
- Whether any To Do feature is reserved for paid Microsoft 365 subscribers. Microsoft states the app is free with a personal Microsoft Account and its listing carries no in-app purchases, but no published page addresses the question in those terms
- Whether Structured requires an account for its Structured Cloud sync, and where that synced data is held, neither of which its listing or help centre states
- How either app performs in practice, which no published source establishes
