All three apps handle events, reminders, and everyday scheduling on Android, and each is free to download. They differ in what surrounds the calendar: Google Calendar connects with Google services, Samsung Calendar is closely tied to Samsung devices, and Outlook combines scheduling with email and contacts.
This comparison weighs their calendar tools, ecosystem fit, trade-offs, and Google Play figures so you can choose the app that suits your accounts and planning habits.
We compared the apps’ scheduling features and stated strengths and limitations, alongside their Google Play ratings, install counts, prices, ad status, and in-app purchase details. The figures were read from Google Play on November 8, 2026.
This is a feature and store-information comparison, not a hands-on test. We did not compare performance or independently verify sync reliability.
Best forplanning across Google services
Google Calendar is the most natural fit for people who already rely on Google services. Multiple calendars, shareable schedules, customizable event notifications, and offline viewing and editing make it flexible for personal and shared plans.
Its 4.6 Google Play rating and 5,000,000,000+ installs are the highest figures among these three apps. The trade-off is its reliance on a Google account and relatively limited theme customization; syncing with some third-party apps can also be inconsistent.
Best forstraightforward planning on Samsung devices

Samsung Electronics Co., Ltd.
Samsung Calendar is geared toward Samsung users who want monthly, weekly, and daily views in a practical, device-integrated app. Event details can include locations, notes, reminders, and repeat schedules, while color coding and widgets help surface plans.
Its Samsung focus is also its main limitation: some features work best within that ecosystem, and collaboration tools are less developed than Google Calendar’s sharing options. A busy set of enabled calendars can also make the interface feel crowded.
Best forcombining work email and scheduling

Microsoft Corporation
Outlook does more than the other two as a combined email, calendar, and contacts app. Its Office integration, scheduling tools, and access across platforms make it a strong choice for people managing work communication and appointments together.
The all-in-one approach can feel overwhelming if you mainly want a simple calendar, and email sync issues may occur. Some features require Microsoft 365, and the app has in-app purchases and ads, unlike the other two in this comparison.

Best for Samsung device owners

Best for email and calendar in one app
Google Calendar is the strongest choice here for sharing calendars with family or colleagues. Samsung Calendar has more limited collaboration tools, while Outlook’s main advantage is combining schedules with email and contacts.
Samsung Calendar is the most closely suited to Samsung devices and accounts, with planning views, widgets, and color-coded events. Google Calendar may be a better fit if you organize around Google services.
Google Calendar supports viewing and editing events offline. Syncing those changes with other services may not always be consistent.
Outlook is free to download, but Google Play lists in-app purchases of $1.99 to $12.99 per item, and some features require a Microsoft 365 subscription.
