Quick verdict
If you're stuck choosing between Google Drive and Microsoft 365 (Office), you're not alone — both are leading Productivity apps on Android and target overlapping audiences.
Google Drive, built by Google LLC, focuses on 15 gb free cloud storage with docs, sheets and slides built in. Microsoft 365 (Office) from Microsoft Corporation instead leans into word, excel, powerpoint and pdf tools in one mobile app. The two products are similar enough that comparing them feature-by-feature, rather than spec-by-spec, gives you a clearer answer.
This guide breaks down what each app does best, the use-cases each was designed for, a clean pros & cons matrix, and three high-intent FAQs people search before downloading. 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.
