Editor's Overview

SyncUp is a cloud storage & file sync application developed by Siddarth Kumar, packaged as a single Android APK of version 1.1 weighing in at 62.1 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 62.1 MB, so it installs quickly even on modest connections.
This build is signed by "Siddarth Kumar" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

An open-source Syncthing client for iPhone and Android, powered by the Syncthing daemon via gomobile.

Syncthing's official Android client was archived in December 2024. No single client ran on both phones from one codebase, so this one was built. The daemon runs in-process via gomobile, with a React Native UI scaffolded from react-native-go.

Differences from other clients:

Daemon runs in-process on Android. The Go daemon lives inside the app via gomobile. There is no subprocess to manage, no IPC between a background service and the UI, and no service-restart handling.

Auto-accept folders from trusted peers. When you add a peer, you can toggle auto-accept so any folder they share is added to your device automatically without a prompt. Other pending offers show up as accept/ignore cards in the Folders tab.

QR pairing works both ways. Display your device's QR for a peer to scan, or scan theirs. The 56-character device ID never needs to be typed by hand.

UI updates in near real time. Long-polling /rest/events means config changes, folder state, and incoming offers reach the UI in about a second, instead of on a polling interval.

Frequently Asked Questions

Is SyncUp free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does SyncUp require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is SyncUp safe to install?
We link to the exact APK published by Siddarth Kumar. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update SyncUp?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.
