Microsoft just rolled a few of the better PowerToys utilities into stock Windows, and the XDA crowd has been arguing about whether that closes the cross-device gap with macOS. It does not. Sending a file from a phone to a PC, mirroring SMS at a desk, copying a link from a laptop to a phone, dragging a screenshot in the other direction: every one of those still asks for an app on the Android side. We tested seven across a Pixel 8a, a Galaxy A55, a Windows 11 laptop, and a Linux desktop to find the picks that earn the install and the picks that should stay uninstalled.
What to look for in a cross-device sync app
A good sync app removes a manual step. A bad one adds three.
- Bidirectional clipboard. Copy on the phone, paste on the desktop. Copy on the desktop, paste on the phone. The benchmark is “instant”, not “after a 10-second sync”.
- File transfer without a cable. AirDrop-style file sends over the local network are the floor; relay-server fallbacks across networks are the ceiling.
- Notification mirroring. Phone notifications surfacing on the desktop is the single biggest quality-of-life upgrade.
- SMS and call handling. Reading and replying to SMS from a desktop is one of the few features iPhone-and-Mac users actually miss.
- Account requirements. KDE Connect and LocalSend run on local discovery with no account. Phone Link asks for a Microsoft account. Pick based on what you already use.

The 7 best cross-device sync apps for Android in 2026
1. Link to Windows, the default for Windows 11 users
Link to Windows is the Android half of Microsoft’s Phone Link feature in Windows 11, and on Samsung and HONOR phones the integration includes app streaming, file drag-and-drop from the Phone Link sidebar, and notification mirroring across the desktop. The base feature set covers SMS replies, call handling, and the gallery sync that surfaces recent screenshots on the laptop. The setup runs through a QR code in Phone Link and survives a phone reboot without the usual reconnect dance.
The Galaxy and HONOR exclusive features are the strongest part. On a Galaxy phone, you can drag a file from File Explorer onto a folder visible in the phone’s storage and back.
Where it falls short: App streaming and the deepest file integration are gated to Samsung and HONOR. Microsoft account sign-in is mandatory, even if you only want SMS sync on a Pixel.
Pricing:
- Free with a Microsoft account.
Platforms: Android, with a Windows 11 desktop Phone Link counterpart.
Bottom line: The default if you live in Windows 11 and you accept the Microsoft account requirement.
2. KDE Connect, the open-source pairing that works on every desktop
KDE Connect is the open-source companion that handles phone-to-desktop pairing on Linux, Windows, and macOS. The Android client pairs over the local network, exchanges encrypted pairing keys once, and then offers clipboard sync, file send, notification mirroring, SMS reply from the desktop, remote keyboard, presentation control, and “find my phone” through any of the desktop clients.
The standout is the platform breadth. The same Android app works against a KDE Plasma laptop, a Windows 11 desktop, a macOS box, and a Raspberry Pi. No account, no telemetry, no cloud relay.
Where it falls short: The discovery requires both devices on the same local network, with no relay-server fallback over the internet. The Windows and macOS clients are less polished than the KDE Plasma original.
Pricing:
- Free, open-source, no ads.
Platforms: Android, Linux (Plasma and other desktops), Windows, macOS.
Bottom line: The pick for anyone on Linux or anyone who refuses to sign into yet another account.
3. AirDroid, the web-based control panel for any browser
AirDroid is the long-running mainstream pick, and the angle is the web client. Pair your phone, open airdroid.com in any browser, and you can browse files, send SMS, control notifications, share the screen, and even type on the phone keyboard from a desktop browser without installing a desktop client. The native Windows and macOS apps add screen mirroring and remote control.
For families and shared workstations, the web-only access is the practical difference: any laptop you sit at becomes a phone-controlling console.
Where it falls short: The free tier caps remote-file transfer at 200 MB per file and limits cloud relay use. The notification surface is more limited than KDE Connect or Pushbullet.
Pricing:
- Free with caps on file size and feature gating.
- Paid Premium for higher caps, file management, and remote camera.
Platforms: Android, iOS, Windows, macOS, browser-based.
Bottom line: Pick this when you want browser-based phone access without installing a desktop client.
4. LocalSend, the pure file-transfer app that does one thing
LocalSend is the open-source AirDrop replacement that runs on every major platform. It is a pure file-transfer tool: launch the app on the phone and the laptop, both devices appear in each other’s discovery list, drag a file across, done. No account, no cloud, no relay server. Transfers happen over the local network with HTTPS encryption.
The advantage is the simplicity. Nothing to sign up for, nothing to configure, and the codebase is open so you can audit what it actually does.
Where it falls short: It does nothing else. No clipboard sync, no notification mirroring, no SMS. If you want a Swiss Army knife, this is not it.
Pricing:
- Free, open-source, no ads.
Platforms: Android, iOS, Windows, macOS, Linux.
Bottom line: The pick if you only need file transfer and you want a tool you can trust by reading the source.
5. Pushbullet, the notification mirror people still come back to
Pushbullet is the senior citizen of cross-device sync. The feature it does best is notification mirroring: every notification that hits your phone appears on a desktop or browser tab, and you can dismiss notifications from the desktop side. SMS and Messenger replies from the browser are clean and quick, and the clipboard sync across phones, tablets, and desktops is reliable.
For knowledge workers who keep a phone face-down all day, the mirror means you never miss the texts or the two-factor codes without giving the phone screen attention.
Where it falls short: The free tier caps SMS and notification volume after a heavy day. The pricing has crept upward over the years.
Pricing:
- Free with monthly caps on SMS and notification volume.
- Pro tier removes caps and adds bigger file transfers.
Platforms: Android, iOS, Windows, macOS, Linux (browser).
Bottom line: The pick if notification mirroring is the one feature you cannot live without.
6. Samsung Flow, the Galaxy-only pairing that beats Phone Link on Galaxy Book
Samsung Flow is the pairing tool Samsung built specifically for Galaxy phone plus Galaxy Book laptop combinations. It handles file transfer, notification mirroring, and clipboard sync, with a passwordless unlock that uses the phone fingerprint to sign in on the laptop. On a Galaxy Book paired with a Galaxy phone, it does what Continuity does on a Mac.
If your hardware is all Samsung, this is the natively integrated option, and the experience is smoother than Phone Link on the same hardware.
Where it falls short: Galaxy hardware only. The desktop client is a Samsung-Windows app and ages without the regular updates Microsoft and Apple ship.
Pricing:
- Free with a Samsung account.
Platforms: Samsung Galaxy phones and Galaxy Book laptops.
Bottom line: Pick this if your laptop and phone are both Samsung and you want the most polished native pairing.
7. Snapdrop for Android, the pure web-style transfer for one-off files
Snapdrop for Android is the Android wrapper around the open-source Snapdrop web tool. Open the app on the phone and Snapdrop in any browser on the laptop, they discover each other over the local network, and a file send is one click. No login, no cloud, no app on the desktop side. Perfect for “send me that PDF” moments at a coffee shop.
The browser-only desktop side is what makes it useful for someone else’s laptop. You do not have to install anything on the destination machine.
Where it falls short: Like LocalSend, it does nothing other than transfer files. The desktop side relies on a public Snapdrop instance unless you self-host.
Pricing:
- Free, open-source.
Platforms: Android, iOS, any browser.
Bottom line: The pick when you want to send a file to a laptop you do not own and have no time to install anything on the destination.
How to pick the right one
The right sync app depends on which desktop you live in and what you actually move across the gap.
- Install Link to Windows if your daily driver is Windows 11 and you already use a Microsoft account.
- Pick KDE Connect if you run Linux, or if you simply want the open-source option that pairs without signing in.
- Use AirDroid when browser-only phone control matters more than the depth of pairing.
- Add LocalSend as a side install for file transfers across any platform with no account.
- Run Pushbullet when notification mirroring is the feature that justifies a subscription.
- Choose Samsung Flow if you own a Galaxy phone and a Galaxy Book and want native pairing.
- Keep Snapdrop for Android on hand for one-off sends to a stranger’s laptop or a borrowed machine.
FAQ
What is the best cross-device sync app for Android and Windows?
Link to Windows is the closest thing to a default if you run Windows 11, because Phone Link is built into the desktop and the Microsoft sign-in is the only account hurdle. KDE Connect is the open-source alternative that works just as well on Windows without an account.
Is there a free AirDrop alternative for Android and Windows?
Yes. LocalSend, KDE Connect, and Snapdrop are all free, open-source, and run on Android, Windows, Mac, and Linux. LocalSend is the closest in feel to AirDrop because it discovers nearby devices automatically and transfers files over the local network.
How do I sync my Android clipboard with a Windows PC?
KDE Connect and Pushbullet both offer bidirectional clipboard sync between Android and Windows. KDE Connect runs entirely on the local network without an account, and Pushbullet uses a cloud relay tied to your account. Microsoft Phone Link supports clipboard sync only for Samsung Galaxy phones.
Can I read and reply to my Android SMS on Windows or Mac?
Link to Windows handles SMS on Windows 11 with any Android phone, KDE Connect handles SMS on Linux, Windows, and macOS, and AirDroid and Pushbullet both handle SMS in any browser. None of these options work for iMessage.
Does Samsung Flow still exist in 2026?
Yes. Samsung continues to publish Samsung Flow and it remains the most integrated pairing tool for Galaxy phones with Galaxy Book laptops, though Microsoft Phone Link has caught up on the cross-Galaxy features that used to be Flow-exclusive.
