Can You Install Apps Directly on a Smartwatch?

Yes, but it depends on the platform

The ability to install apps directly on a smartwatch, without a phone nearby, depends entirely on the operating system. Two major platforms support watch-side app stores: watchOS on the Apple Watch and Wear OS by Google. Both let you open a store app on the watch, browse, and download apps over Wi-Fi or cellular. Other platforms, including Garmin, Amazfit, and most budget fitness watches, do not have a watch-side store; you install apps and watch faces from the companion phone app instead.

Even on Apple Watch and Wear OS, the phone is not optional at the start. The first-time setup and pairing process requires the companion phone app. After that, the watch can manage app installs on its own, as long as it has a network connection. For a deeper look at the pairing process, see how to pair an Apple Watch and how to pair a Wear OS watch.

Apple Watch: the App Store is on the wrist

Apple Watch runs watchOS, and the platform includes an App Store app directly on the watch. The Apple Watch User Guide lists the App Store among the built-in apps, and the watch can browse featured apps, search, and install them over Wi-Fi or cellular. The app store on the watch is designed for the small screen: it shows a curated selection and lets you search for specific apps.

Cellular models can install apps without the iPhone nearby, because the watch has its own network connection. But even on Wi-Fi-only models, the watch can install apps as long as it is on a known Wi-Fi network. The phone is still needed for initial setup, for managing some settings, and for installing apps that are not available in the watch-side store.

Wear OS: Google Play on the wrist

Wear OS by Google also includes a Google Play store on the watch. The Wear OS website describes the platform's apps as available on Google Play, and many Wear OS watches include a Play Store app that lets you browse and install apps directly. This works over Wi-Fi or LTE, depending on the watch model.

As with Apple Watch, the first-time setup requires an Android phone (or iPhone, with some limitations). After setup, the watch can install apps on its own. Some Wear OS watches also support sideloading APKs, but that is not a supported workflow and carries security risks.

If you are deciding between Wear OS models, the best Wear OS smartwatches in 2026 and best Wear OS smartwatches with LTE are good starting points.

Most other platforms install from the phone app

Garmin, Amazfit, and most budget-oriented smartwatches do not have a watch-side app store. You install apps, watch faces, and data fields from the companion phone app, which pushes them to the watch over Bluetooth or Wi-Fi. The watch itself has no storefront, and there is no way to browse or install apps from the wrist.

This does not mean the watch is limited. These platforms include built-in apps for fitness, heart rate, sleep, and notifications, and many support adding apps from the phone app. But if you want the freedom to install a new app while away from your phone, these platforms will not give it to you.

What the phone is still for

Even on platforms with watch-side stores, the phone remains important. You need it for initial pairing, for account setup, for updating the watch OS, and for managing settings like notifications and privacy. Some apps, especially those that sync health data to a cloud service, require the phone app to be installed and configured.

If you rarely carry your phone, look for a smartwatch with cellular connectivity. See cellular vs Bluetooth smartwatch to understand the tradeoffs.

Kids' watches and family setup

For kids' smartwatches, the app install question often comes with extra controls. Apple's Family Setup lets a parent manage a child's Apple Watch from the parent's iPhone, and the child can still use the App Store on the watch, subject to parental controls. On the Android side, Kids' smartwatches aimed at children under 13 are subject to the Children's Online Privacy Protection Act (COPPA), which the FTC enforces. The FTC explains that covered sites and services must get parental consent before collecting personal information from children under 13.

If you are choosing a watch for a child, consider how app installs and data collection are handled, and look for options with strong parental controls. The best kids' smartwatches in 2026 is a good place to compare. See also kids smartwatch parental controls and kids smartwatch privacy checklist.

Can I install apps on an Apple Watch without the iPhone?

Yes, once the watch is set up. The App Store is available on the watch, and it can install apps over Wi-Fi or cellular. Cellular models can do this without the iPhone nearby, but Wi-Fi-only models need a known Wi-Fi network.

Do Garmin or Amazfit watches have a watch-side app store?

No. Garmin and Amazfit do not have app stores on the watch. You install apps, watch faces, and data fields from the companion phone app, which sends them to the watch over Bluetooth or Wi-Fi.
