#6 in Productivity Apps
of 14 ranked entries
Slack
Salesforce · team messaging · 2013
Turned workplace messaging into searchable, channelised history instead of a scattered email chain — the notification design is the one place it still actively works against focus. Recorded specifics: price 96, released 2013, active users 65 M. Panel highlighted searchable history makes institutional knowledge actually findable and integration ecosystem covers most existing workplace tools. The reservation on record is default notification settings actively fragment attention.

Ranked alongside it
Rank 01Editor’s pickMeta · messaging · 2009
End-to-end encryption is on by default for two billion people who never had to opt into it, and the app still works reliably on a two-bar connection in places carriers barely cover.
98.3/100 Top 49 score—No change
Rank 02Editor’s pickGoogle Maps
Google · navigation · 2005
Still the app that reroutes around a crash before the crash is officially reported, built on a live traffic dataset no competitor matches at this scale.
96.6/100 Top 49 score2Up 2
Rank 03Editor’s pickSpotify
Spotify · music streaming · 2008
The recommendation engine is the actual product now, not the catalogue — Discover Weekly still surfaces tracks competitors’ algorithms miss, even as per-stream artist payouts stay a real sore point.
95.3/100 Top 49 score—No change
Rank 04Editor’s pickYouTube
Google · video · 2005
The free tier is genuinely usable, which is rarer than it sounds — the paid tier mostly just removes the friction the free tier was designed to create.

Rank 05Gmail
Google · email · 2004
Spam filtering quietly catches the overwhelming majority of junk before it is ever seen, and the search bar alone has replaced a folder system for most users.

Rank 06Meta · photo and video · 2010
Reels chasing TikTok’s format changed the app’s whole rhythm, and the tradeoff is a feed that increasingly shows content from accounts you do not follow.
89.7/100 Top 49 score4Up 4
Rank 07Signal
Signal Foundation · private messaging · 2014
No ads, no data harvesting, and a funding model — donations and a nonprofit foundation — built specifically so that incentive never creeps in. The tradeoff is a smaller network than WhatsApp’s.
88.3/100 Top 49 score—No change
Rank 08Uber
Uber Technologies · ride-hailing · 2010
Surge pricing is the most visibly unpopular feature and also the mechanism that keeps a car available at 2am — the app’s reliability during exactly the moments you need it most is the real product.
