About this app

QuestSync is an auto sync and backup app for Android. Back up photos, videos and any folder on your phone to Google Drive, Dropbox, OneDrive and 25+ other clouds and servers. You can also sync folders both ways, copy files from one cloud to another, and send files to a nearby phone without a cable. No computer needed.

★ AUTO BACKUP FOR PHOTOS & FOLDERS
• Back up your camera photos, videos, WhatsApp media, Downloads or any folder automatically
• Run it hourly, daily or weekly
• Only on Wi-Fi, or only while charging, to save mobile data and battery
• Uploads only new and changed files, so backups stay fast
• Free up phone storage without losing your photos

★ FOLDER SYNC: ONE-WAY OR TWO-WAY
Pick a sync mode for each folder pair:
• Backup: copy new and changed files
• Two-way sync: keep both sides the same, whichever one changes
• Mirror: make the destination an exact copy of the source
• Move: transfer the files, then free up space on the source

★ CLOUD TO CLOUD TRANSFER
Copy Google Drive to Dropbox, move OneDrive to Google Drive, or merge old accounts into one, all from your phone. Files go straight from one cloud to the other, with no computer and no re-uploading from your PC.

★ WORKS WITH 25+ CLOUDS, NAS & SERVERS
Google Drive, Dropbox, OneDrive, Box, pCloud, MEGA, iCloud Drive, Proton Drive, Yandex Disk, Koofr, Internxt, Jottacloud, OpenDrive, Mail.ru Cloud, Amazon S3, Backblaze B2, Azure Blob, Storj, Nextcloud, Seafile, plus any SFTP, FTP, WebDAV or SMB / Windows share. Back up to a NAS (Synology, QNAP, TrueNAS) or a home server over your own network. Open every account side by side and transfer between any two.

★ INSTASEND: SEND FILES NEARBY
Send files or folders to any phone or laptop on the same Wi-Fi in seconds. The other person scans a QR code and the download opens in their browser. They don't need to install anything, there's no cable, and nothing is uploaded to the internet. With InstaReceive, you scan a code and save the incoming files straight into any connected cloud.

★ TRANSFERS THAT FINISH
Large uploads keep going in the background. If you leave the app, lock the screen, switch networks or restart the phone, QuestSync picks up where it stopped. A live progress notification shows how far it has got.

★ PRIVATE BY DESIGN
QuestSync has no file servers of its own. Your files go straight from your phone to your cloud accounts. Your cloud logins are encrypted on your device and never sent to us.

★ FREE & PRO
Free: on-demand phone backups, InstaSend and occasional cloud transfers.
Pro: scheduled auto sync, two-way sync, mirror, move, faster multi-threaded transfers, unlimited InstaSend / InstaReceive and direct support.
