Most cleaning apps on the App Store focus on the photo library. Zero Duplicates focuses on your files: the downloads, documents, PDFs, videos and audio files that pile up in the Files app and quietly fill your storage. Zero Duplicates compares files by their content, not by their names. A renamed download, an attachment saved twice, a document copied into three folders: all of them are found, even when the file names look nothing alike. MADE FOR THE FILES ON YOUR DEVICE • Scan any folder you choose: On My iPhone, iCloud Drive, external drives • Downloads from Safari, Mail and Messages • Documents: PDF, Word, Excel, Pages, Numbers, Keynote • Images, videos, audio recordings, archives and more • USB drives and SD cards (with adapter) CONTENT MATCHING File names lie. Zero Duplicates reads the actual content of every file, so duplicates are found even when they were renamed, moved or saved from different apps. AUTO-SELECT IN SECONDS Automatic selection keeps the newest or the oldest file in every duplicate group. Review, tap once, done. No scrolling through hundreds of files by hand. SEE BEFORE YOU DELETE Every duplicate can be previewed before deletion, and you choose which copy stays. At least one version of every file always remains, so losing all copies is impossible. Deletion is permanent, so nothing is removed without a clear confirmation first. PRIVATE BY DESIGN Scanning happens entirely on your device. Your files are never uploaded anywhere. HOW IT WORKS Pick a folder, scan, review what was found, delete with confidence. Three steps to a cleaner device. System files are protected automatically. Perfect for: • Anyone seeing "Storage Almost Full" warnings • People who download and share lots of files • Managing documents, media and work files on the go • Cleaning up iCloud Drive across devices TRY WITHOUT RISK Free to download • Unlimited scans • 500 MB free deletion Premium unlocks unlimited deletion and advanced features.

About

Server Dock

Features
Read full description

Palworld, Minecraft Java—and even the apocalypse. Server Dock is an unofficial app for monitoring and managing dedicated game servers and their Linux or Windows hosts from iPhone and iPad. Monitor Palworld, Minecraft Java Edition, 7 Days to Die, and SSH hosts—all in one app. You can manage the servers. The zombies, unfortunately, are beyond our control. Supported Connections • Palworld: REST API / RCON • Minecraft Java Edition: Server List Ping / RCON • 7 Days to Die: Telnet / game query • Linux and Windows hosts: SSH Key Features • Availability, response times, player counts, and server details • Player lists, moderation, and ban management • Connection diagnostics • Local and VPN destinations • Multiple servers, favorites, custom ordering, and bulk refresh • Game-based and host-based layouts • Standard and compact display modes • Manual and foreground automatic refresh • Player and server FPS trends • Home Screen widgets with direct refresh • iCloud settings backups • Auto-Lock prevention and a screen saver SSH Host Management Register Linux and Windows machines and monitor CPU, memory, disk usage, uptime, latency, OS information, and resource history. Link game servers to their hosts, organize parent and child hosts, and check which servers will be affected before restarting or shutting down a machine. Monitor and control systemd units and Windows Services, check their status, and view supported logs through SSH. Palworld The REST API provides player information, server settings, metrics, Game Data, and a simplified server map. Record server FPS on-device and view its history. RCON supports player retrieval, messages, world saves, kick, ban, unban, server stop, and custom commands. Game Data features require the server’s Game Data API. Minecraft Java Edition Server List Ping checks availability, version, MOTD, player counts, and response time without a password. Adding RCON enables player lists, world saves, messages, kick, ban, unban, server stop, and custom commands. If the server does not publish player names, only the player count is shown. 7 Days to Die Use Telnet to check the server version, players, in-game time, and the next Blood Moon. Player details can include IDs, IP address, ping, level, statistics, and coordinates. Supported servers can save the world, send messages, manage players and bans, shut down normally, and run Telnet commands. The live console offers raw and summarized logs, search, auto-scroll, pause, automatic reconnection, and command entry. Free Version The free version supports one game server with manual refresh, status monitoring, player information, and supported moderation actions. Full Version The Full Version is a one-time purchase. It unlocks multiple servers, SSH host addition and management, automatic and bulk refresh, widgets, server-wide operations, ban history, Palworld Game Data and maps, player and server FPS trends, iCloud backups, automatic Local/VPN switching, Auto-Lock prevention, and the screen saver. For 7 Days to Die, it also unlocks world status, the player coordinate map, world saves, messages, normal shutdown, and the live console. Before You Begin Server Dock requires supported dedicated servers and SSH hosts that you manage. Features vary by game, connection method, operating system, and server configuration. Automatic refresh runs while Server Dock is visible. Only Minecraft Java Edition is supported. Bedrock Edition, TPS history, and plugin integrations are not supported. Palworld REST API, RCON, and 7 Days to Die Telnet do not encrypt traffic. Never expose management ports directly to the internet. Use a trusted LAN or a properly configured VPN such as WireGuard or Tailscale. Server Dock is unofficial and is not affiliated with or endorsed by Pocketpair, Inc., Microsoft, Mojang Studios, or the teams behind supported games. Games and server software are not included.
