Free encrypted messaging with 32-person calls and 24-hour Status posts
The apps at the top of this list share one trait: each has over 10 billion installs on Google Play. That makes raw popularity a poor way to tell them apart, so this page groups them by job instead.
The catalog holds 1,052 Android apps, and 436 of them carry no ads. Among the leaders, WhatsApp covers private messaging, Facebook covers social networking, Google Photos handles cloud storage for pictures, Google Chrome handles browsing, and Gboard handles typing. Most are free, though WhatsApp, Facebook, YouTube and Google Drive include in-app purchases.
Pick the job you need done first, then compare the app that does it. Each entry below lists the Google Play rating, the ad situation and one concrete feature.

The messaging pick. WhatsApp is free, shows no ads, and encrypts personal messages and calls end to end. Google Play rates it 4.6, and the download is about 148.6 MB. It works on mobile and desktop, including over slow connections, and in-app purchases exist.
The social network pick. Facebook combines a personalized Feed, Marketplace for buying and selling, reels and a Meta AI assistant. Google Play rates it 4.6. It is free but shows ads and includes in-app purchases, which matters if you want a quieter feed.
The photo storage pick. Google Photos backs up pictures and videos, and every Google account gets up to 15 GB of storage. Backed-up photos can be cleared from the phone in one tap. It is free, ad-free and has no in-app purchases. Google Play rates it 4.4.
The browser pick. Chrome from Google adds voice search, Google Lens and Translate for more than 130 languages. Enhanced Protection mode raises its security level. Google Play rates it 4.1. It is free, has no in-app purchases and does show ads.
The typing pick. Gboard supports Glide Typing, voice typing, handwriting, emoji search and GIFs. Sliding across the space bar moves the cursor. It does not support Android Go devices. Google Play rates it 4.5, and it is free with no ads.
All ten apps in the top group have over 10 billion installs on Google Play. That includes WhatsApp, Facebook, YouTube, Google Photos and Google Chrome, so install count alone will not separate them.
WhatsApp, Google Photos, Google Calendar, Gboard, Google Meet, Google Drive and Google TV are listed without ads. Facebook, YouTube and Google Chrome do show ads. Across the whole catalog, 436 apps are ad-free.
Yes, every app in this group is free to install. WhatsApp, Facebook, YouTube, Google Drive and Google TV also include in-app purchases, while Google Photos, Chrome, Calendar, Gboard and Meet do not.
Before installing, check the details that differ between apps of similar popularity. Gboard, for example, skips Android Go devices, and Google Meet notes that live captions and speech translation are not offered in every language. Google Calendar can pull flight and hotel bookings from Gmail, which saves manual entry if you already use that account.
The update dates also help. Most of these apps were refreshed between October 29 and November 4, 2026, so each page shows a current build to compare.
