Quick verdict
If you're stuck choosing between TikTok and Facebook, you're not alone — both are leading Social apps on Android and target overlapping audiences.
TikTok, built by TikTok Pte. Ltd., focuses on short-form video feed powered by an algorithm that learns what you love. Facebook from Meta Platforms, Inc. instead leans into stay connected with friends, groups, marketplace and short-form reels. The two products are similar enough that comparing them feature-by-feature, rather than spec-by-spec, gives you a clearer answer.

Both are free to install from the Play Store, so the real cost is your attention and habit — pick the one whose workflow matches yours.
