Verdict

The call

Microsoft Outlook and Google One both sit at 4.8 stars, but that hides the real split: 65% of Microsoft Outlook's written reviews are positive against 28% of Google One's. Microsoft Outlook also leads on ratings volume (9.4M vs 23K) and chart position (#11 vs #40). Google One's advantage is ads (none vs shown) and iOS requirement (17.0 vs 26.0). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Microsoft Outlook sells 3 in-app purchases, starting at $1.99 per month and Google One sells 9 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

On the App Store both sit at effectively the same score — 4.8 for Microsoft Outlook against 4.7 for Google One. That said, the two scores are not equally well evidenced: Microsoft Outlook has 9.4M ratings behind it against 23K, so its average is the more settled of the two. Written reviews are what separate them: 65% of Microsoft Outlook's written reviews are positive against 28% of Google One's.

UpkeepUpdate frequency

Microsoft Outlook ships an update weekly, Google One fortnightly. Both last shipped on November 5, 2026.
