Sarah Perez, writing for TechCrunch:

Mobile applications from Facebook and Google dominated the new list of the year’s top apps released today by Nielsen. Not surprisingly, Facebook again grabbed the number one spot on the list, with more than 146 million average unique users per month, and 14 percent growth over last year. In fact, Facebook scored several spots on the top 10 chart, thanks to Messenger (#2) and Instagram (#8) – the latter which also showed some of the highest year-over-year growth, up 36 percent from 2015.

Messenger came in second place this year, with over 129 million average unique monthly users, followed by YouTube with over 113 monthly uniques.

However, it was Google, not Facebook, that grabbed the most spots on the year-end chart.

I assume that Nielsen’s study accounts for both the App Store and Google Play Store (iOS and Android apps), but their findings match the general state of the iOS App Store’s top charts. Notably, the only Apple-made app to make it into the Top 10 is Apple Music, which launched in June 2015 and has 20 million paying subscribers, though Nielsen reports over 68 million “average unique users” for it (Free users? Non-subscriber usage? Family accounts? I’d love to know their methodology for this).
