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 iPhone and iPad app for monitoring and managing your dedicated game servers. Monitor Palworld, Minecraft Java Edition, and 7 Days to Die servers—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 checks Key Features • Server setup by game and connection method • Availability, response times, player counts, and server details • Player lists and details • Kick, ban, unban, and other moderation tools • Connection diagnostics • Local and VPN destinations with switching • Multiple servers, favorites, and bulk refresh • Manual and foreground auto-refresh • Standard and compact server-list layouts • Player trends and weekday-by-hour heatmaps • Home Screen widgets • iCloud settings backups • Auto-Lock prevention and a screen saver • English, Japanese, Korean, Simplified Chinese 7 Days to Die Use Telnet to check the server version, player count and details, in-game date and time, and the next Blood Moon. Player details can include entity and platform IDs, IP address, ping, level, status, statistics, and coordinates. View locations on a coordinate map without terrain data. Supported servers can save the world, send messages, kick players, create timed bans, show the server ban list, unban players, shut down normally, and run Telnet commands. The live console offers raw and summarized logs, search, auto-scroll, pause, automatic reconnection, and command entry. Palworld The REST API provides player information, server settings, metrics, Game Data, and a simplified server map. Record server FPS on-device and view daily, weekly, and monthly trends. 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, online and maximum 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. With RCON, Server Dock attempts to retrieve names using the “list” command. Free Version The free version supports one server, manual refresh, status monitoring, player lists and details, and supported actions such as kick, ban, and unban. Both Local and VPN destinations can be saved and switched manually. Full Version The Full Version is a one-time purchase. It unlocks multiple servers, automatic and bulk refresh, Home Screen widgets, server-wide operations, ban history, Palworld Game Data and maps, player and server FPS trends, iCloud backup creation, 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 a supported dedicated game server that you manage. Features vary by game, connection method, 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 are server-provided connection methods that do not encrypt traffic; this is not a Server Dock limitation. 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 an unofficial server-management app. It is not official, affiliated with, or endorsed by Pocketpair, Inc., Microsoft, Mojang Studios, or the teams behind supported games. Games and server software are not included.
