April is behind us, which means it's time to look at the most downloaded apps - I did, and can tell you April was a weird month...

And by weird I mean stagnant.
Instagram was the most downloaded app in the world in April. Our estimates show it made its way into 55M more devices globally. Instagram rose a single rank and dethroned sibling Facebook, which dropped to second place.
Facebook's issue-less month meant a drop in downloads, but it's still growing! Our App Intelligence shows Facebook was downloaded 48M times from the App Store and Google Play in April.
TikTok, WhatsApp, and Telegram round out the top 5 most downloaded apps in April. Even though their ranks are the same as they were in March, downloads rose a bit across all three.
A few highlights:
Together, the top 10 most downloaded apps in the world saw 325M downloads in April, according to our App Intelligence. A bit short when compared to March, but March was a pretty big month all around so this isn't a surprise.
ChatGPT's mobile app is no longer alone in AI, but Appfigures estimates show it is still the revenue leader by a wide margin.
HBO Max filled its biggest remaining European gaps in 2026. The UK brought the biggest mobile audience, while Germany and Switzerland showed stronger revenue depth.
