WhatsApp may be the statistically best app we've ever made.
It's a product manager's dream with its unparalleled addictiveness (DAU / MAU) of 87% and stickiness (M1 retention) of 86%, both #1 in the world while having the #1 most monthly active users for any non preinstalled app of 2.7B users.
Here are the top 25 most used apps in the world by MAU on both these metrics. Some surprising observations: — There are now 15 1B+ user apps in the world, 8 by Google, 4 by Meta. — The 3 that aren't are TikTok, Telegram (!) and ChatGPT — Telegram has more users than Spotify, Pinterest, Netflix, Amazon, Snap! — ChatGPT's one month retention is #5 after WA, Instagram, Chrome and Youtube. 2yrs ago, it was been #20 by M1 retention — Shopee, a shopping app in southeast Asia, is huge and retains users better than Amazon!
Useful way to break down consumer businesses especially within certain categories (X vs Reddit vs Threads is a good one). It's shocking how few new apps have been able to break through in the past 10yrs.
