Best Productivity Apps for iPhone, Ranked by Our Scores
Things 3 is the highest-scored productivity app on this site at 8.5, and it is the only one on the list that costs money — $9.99 once, with no subscri
Outlook holds Outlook.com, Microsoft 365, Gmail, Yahoo and IMAP accounts in one inbox, splits arrivals into Focused and Other, and now carries Copilot: thread summaries with citations, drafts written from a one-line instruction, and tone coaching before sending. Those AI parts need a paid subscription. The free inbox carries advertising, and Google Play lists emails among the data collected.
Specs come from the official store listings and were last checked on 2026-09-07. Developers change pricing and requirements — check the store page before installing.
A long thread collapses into a Summary by Copilot panel where each point is footnoted to the message it came from: who asked about the meeting, who agreed to carpool, who committed to 6:00pm and a 5:45pm pickup. The citations are what make it usable, because a wrong summary can be traced rather than believed. A second mode drafts from an instruction typed in plain language — write a save-the-date notice for a wedding in the fall — and a third, Coaching, rates a finished draft on tone and reader sentiment, then offers Apply all suggestions, Retry or Discard as the only three responses.
The account rail down the left edge stacks Microsoft 365, Outlook.com, Google, Yahoo and generic mailboxes, each keeping its own folders: Inbox, Family, Taxes, Drafts, Archive, Sent, Snoozed, Deleted, Junk, Projects. The Focused and Other tabs sort arrivals so that newsletters and receipts stop competing with real mail, and a filter control sits beside them. Calendar invitations are answered without leaving the list — an event on Monday 9 August at 5:00pm carries its own RSVP button in the message row — and the bottom bar keeps Email, Calendar and Apps one tap apart.
The Play listing carries both a Contains ads badge and in-app purchases, against a billion installs and 4.3 stars from 10.6 million reviews; the App Store shows 4.8 from 9.2 million ratings for the same product. Copilot comes with Microsoft 365 Personal at $9.99 a month or $99.99 a year, or Family at $12.99 and $129.99 — where the AI features belong to the subscription owner alone and cannot be shared with the other five people on the plan. Emails, calendar events, contacts, photos and files are all listed as collected, with device IDs shared onward.

The best reason to choose it is Copilot's summary with citations — a rare case of AI in a mail client that can be checked rather than trusted. The rest is a solid multi-account inbox with a calendar attached. The costs are visible: advertising in the free version, $9.99 a month for the AI, and a data card that includes the emails themselves. Reasonable if you already pay for Microsoft 365.

The app is free and works with any supported mail account. Two things are not free: the inbox shows advertising unless a subscription removes it, and the Copilot features are unavailable without Microsoft 365. Everything conventional — mail, folders, calendar, search, multiple accounts — costs nothing.
Three jobs: it summarises a long thread into numbered points with a citation on each, drafts a message from an instruction typed in ordinary language, and coaches a finished draft on tone and reader sentiment. The summary's citations let you check any claim against the original message.
Microsoft 365 Personal is $9.99 a month or $99.99 a year with 1 TB of storage; Family is $12.99 or $129.99 and covers six people with 1 TB each. Copilot is included in both, though on Family only the owner gets the AI features. Prices are US figures.
Yes — a Gmail account added here keeps its own folder tree and appears alongside the others, with Focused inbox, snoozing and swipe actions applied to it. The trade is that mail passes through Microsoft's service for those features, which some workplaces and privacy-minded users specifically avoid.
Gmail's own app handles multiple providers too and shows no ads on non-Gmail accounts. Apple Mail is lighter and free of AI upselling on iPhone. Neither offers thread summaries with citations, which is currently the strongest argument for staying with this one.
