Google Drive, OneDrive, Dropbox, and other cloud services don’t offer built-in tools to find and remove duplicates. If you store many files in the cloud, it’s easy to lose control and waste space. Automatic mobile backups make this problem even worse. DeDuplicate scans your cloud storage, finds identical files, and lets you remove the extra copies to free up space. How it works: 1) Log into your account. 2) Choose one or more folders (or the entire drive) and start the scan. Scan time depends on the NUMBER of files, not their size. 3) Review the detected duplicates and optionally ignore some of them. 4) Confirm the operation. What makes DeDuplicate different: • Efficient and fast: files are NOT downloaded. DeDuplicate uses metadata provided by cloud services, so it saves bandwidth, requires no extra storage, and scans are very quick (e.g. ~100,000 files in under 10 minutes, depending on network speed). • Accurate detection: only EXACT duplicates are detected using file hash values. File names are ignored; contents must be identical. • Privacy-first: everything runs locally on your device. The app connects directly to cloud providers, with no intermediary servers and no file data collection. • Cross-platform support. DeDuplicate currently supports the following cloud services: (PERSONAL ACCOUNTS - see notes below!) • OneDrive • Dropbox • Google Drive (∗) • MEGA • Box • pCloud • Yandex.Disk IMPORTANT: DeDuplicate is designed and tested primarily with PERSONAL/CONSUMER ACCOUNTS. Business, school, or enterprise accounts may behave differently and are not fully supported yet. Improving support for those account types is planned for a future update! NOTES ABOUT GOOGLE DRIVE: - Due to recent changes in Google’s requirements for third-party apps, DeDuplicate currently does not have a “verified” status. You can still use Google Drive normally, but signing in requires a small workaround, which is explained step by step inside the app! - Google proprietary file types (such as Google Docs, Google Sheets, etc.) are treated specially by Google Drive and are NOT included in DeDuplicate’s scan. WHY DO YOU NEED THIS APP? Until now, the only practical way to remove duplicates from cloud storage was a very time-consuming workaround: downloading everything to your computer, using one of the many “offline” duplicate-file utilities, and then syncing the changes back to the cloud. In the worst-case scenario, this even means re-uploading everything from scratch. That’s hardly a viable option when you have over 500 GB of unorganized cat pictures :) DeDuplicate is actively developed. If you encounter any issues, please take the time to contact us!

SynoDocker is an app for signing in to Synology DSM and managing containers in Container Manager—without sitting at a computer. WHY SYNODOCKER If you run Home Assistant, Plex, reverse proxies, or other services in Container Manager, you often need a quick look at what is running, why something stopped, or a way to restart it while you are away. SynoDocker talks directly to your NAS. There is no SynoDocker cloud account and no extra server in the middle. SIGN IN YOUR WAY • Local IP, DDNS hostname, or QuickConnect ID • HTTP or HTTPS, including self-signed certificates on networks you trust • Common DSM ports (HTTP 5000, HTTPS 5001), or QuickConnect with no port to fill in • DSM username and password (not a QuickConnect account) • Two-factor authentication with a one-time code and a Paste shortcut • Optional Remember sign-in: the session is stored in the on-device Keychain and cleared when you sign out CONTAINER LIST After sign-in you can: • See every container’s name, image, and running or stopped status • Check CPU, memory, and network overview at a glance • Search by name or image • Filter All / Running / Stopped • Pull to refresh, or turn on auto-refresh (3, 5, 10, 30 seconds, or a custom 1–3600 seconds) The list is available after sign-in. Opening a container for full details is a premium feature. CONTAINER DETAILS (PREMIUM) Unlock monthly, yearly, or lifetime to: • View live CPU and memory • See container ID, image, project, CPU priority, memory limit, auto-restart, and web portal • Inspect network mode, gateway, IP, MAC address, restart policy, and port mappings • Read real volume mount paths and the start command • Browse environment variables as KEY / VALUE • Scroll recent logs (ANSI color codes stripped) • Long-press to copy logs, env vars, mounts, command, gateway, IP, MAC, and ports • Start, stop, restart, or force-stop a container (force-stop is for unresponsive containers—use with care) DEMO MODE Tap Try Demo on the sign-in screen to explore six sample containers with no NAS. Demo data is discarded when you leave. PRIVACY Login and container traffic go from your iPhone to the NAS you enter (and to Synology QuickConnect only if you use a QuickConnect ID). Container lists, logs, and environment variables are not uploaded to us. Purchases are handled by Apple. WHAT YOU NEED • iPhone, iOS 17 or later • A Synology NAS with Container Manager (or the older Docker package) installed and running • A DSM account allowed to use that package SUBSCRIPTIONS • Monthly — auto-renews every month • Yearly — auto-renews every year • Lifetime — one-time purchase, no renewal The container list is included after sign-in. Container details, logs, configuration, and start/stop/restart require an active subscription or a lifetime purchase. Prices are shown in the app and charged to your Apple ID. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours prior to the end of the current period. Manage or cancel anytime: iPhone Settings → Apple ID → Subscriptions, or Manage Subscription in the app. Restore purchases on a new device with the same Apple ID.

Verdict
The clearest difference is price: SynoDocker at Free against DeDuplicate's $7.99. SynoDocker also leads on rating (5.0 vs 4.5). DeDuplicate's advantage is ratings volume (129 vs 1) and update cadence (every 2 weeks vs every 6 weeks). On ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
SynoDocker is free to download; DeDuplicate costs $7.99 up front. DeDuplicate sells 2 one-off in-app purchases and SynoDocker sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
SynoDocker holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: DeDuplicate has 129 ratings behind it against 1, so its average is the more settled of the two.
DeDuplicate ships an update every 2 weeks, SynoDocker every 6 weeks. The most recent releases landed on October 21, 2026 and October 16, 2026 respectively.
