QuestSync: Cloud Sync & Backup

QuestSync is the cloud storage manager and file transfer app built for your phone. Back up your Camera Roll, Downloads, or any folder straight from your Android phone to the cloud, beam files to a nearby phone in seconds, or move files between two cloud drives — all without ever touching a computer.

BACK UP YOUR PHONE, AUTOMATICALLY
Point QuestSync at Photos, Downloads, or any folder and back it up to your cloud on a schedule — hourly, daily, on Wi-Fi only, or only while charging. Free your phone's storage without losing a single photo.

INSTASEND — SHARE FILES NEARBY, NO CLOUD NEEDED
Send a file or folder to any phone or laptop on the same Wi-Fi in seconds. The other person scans a QR code and the download starts straight in their browser — no app install, no cable, no internet upload. InstaReceive works the other way: scan a code and save incoming files directly into any connected cloud.

ONE APP FOR EVERY CLOUD STORAGE SERVICE
Connect Google Drive, Dropbox, OneDrive, Box, pCloud, Backblaze B2, MEGA, iCloud Drive, Internxt, Yandex Disk, Koofr, Proton Drive, Jottacloud, and OpenDrive — plus Amazon S3, Azure Blob, Nextcloud, and any SFTP, FTP, SMB, or WebDAV server. Browse every account side by side and move files between any two, or between your phone and any cloud.

CLOUD-TO-CLOUD FILE TRANSFER, NO COMPUTER REQUIRED
Copy Google Drive to Dropbox, migrate OneDrive to Google Drive, or consolidate old accounts into one — directly from your phone. Choose Back up (copy new & changed files), Sync (two-way), Mirror (make destination identical), or Move (transfer then delete from source).

TRANSFERS THAT ACTUALLY FINISH
Every transfer is guaranteed to complete. Leave the app, lock your screen, switch networks, or restart your phone — QuestSync resumes exactly where it left off, with a live progress notification the whole time. No more failed uploads or half-finished backups.

SET IT AND FORGET IT
Schedule recurring syncs hourly, daily, or weekly, restrict them to Wi-Fi or charging, and let QuestSync run reliably in the background while you do anything else.

PRIVATE BY DESIGN —
QuestSync has no servers of its own. Your files move directly between your phone and your cloud accounts, end to end. Your cloud logins are encrypted on your device and never sent anywhere else — your data stays yours.

FREE & PRO
Free covers on-demand phone backups, InstaSend, and occasional cloud transfers. Pro unlocks scheduling, Sync, Mirror, Move, faster multi-threaded transfers, unlimited InstaSend/InstaReceive, and direct support — for less than two coffees a year.

Google Drive, Dropbox, OneDrive, iCloud, MEGA, Box, pCloud, S3 — whatever clouds you use, QuestSync keeps them backed up, synced, and organized from the phone in your pocket.
