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.

HoloChat Pro

Meet Holo Chat Pro — the universal AI chat app that connects to any OpenAI-compatible API, and puts 31+ real-world tools at your fingertips. This app does not provide any API service. You bring your own API key from your preferred AI provider, and you are responsible for its availability and usage. Holo Chat Pro simply connects you to the models you already have access to. Connect to OpenAI, or use OpenRouter to access Claude, Gemini, Grok, DeepSeek, Qwen, GLM, Groq, local LLMs, and hundreds more. No subscriptions to this app. You pay only for the models you use, at your provider's direct prices. Switch between models instantly — save multiple API profiles and jump from DeepSeek to Claude to Qwen with one tap. No need to reconfigure every time. Prompt caching support for compatible models can significantly reduce your token usage on long conversations — potentially cutting API costs by half or more on repeated context. Why Holo Chat Pro is different Most AI chat apps can only talk. Holo Chat Pro can act. Your AI searches the web, runs code, downloads files, reads and writes project files, sends emails, sets calendar events, checks your location, opens navigation, plays music, generates PDFs — 31+ tools in one conversation. Extend the AI with custom skills Tell the AI to write and run custom scripts on the fly — process data, generate html, svgs. If the 31+ built-in tools aren't enough, the AI creates what you need. True multimodal conversations Send images, record voice memos, attach video files. Receive image and audio replies. The AI sees and hears what you do, all in one thread. Beautiful message rendering Markdown formatting, LaTeX math formulas, Mermaid diagrams, syntax-highlighted code, and live previews of SVG and HTML — all rendered natively in your conversation. Tap any message for full-screen reading. Smart conversation management Color-coded tags for effortless organization. Filter, batch-select, bulk-tag, and auto-summarize with AI. Search titles and message content. Lock conversations with Face ID or Touch ID. Your conversations, your files Every chat is saved as an individual file on your device. Browse, copy, back up, edit, or transfer them through the Files app. No lock-in, no gatekeeping. Project-linked coding assistant Link a conversation to a local project folder. Your AI can read, write, search, and manage your project files. Home screen widgets Three widget sizes show your recent conversations with colors that match your app theme. Full desktop-grade WebUI Holo Chat Pro includes a powerful web interface that turns any browser on your network into a management console. Browse conversations, edit profiles, manage backups, organize projects, curate app whitelist, maintain system prompt templates, and upload music files. The built-in model browser lets you explore hundreds of OpenRouter models with smart filters for Tools, Reasoning, Structured Outputs, and Vision support — plus expiration warnings so you are never caught off guard by a deprecated model. Recycle Bin Deleted conversations stay in the trash for 30 days. Recover or permanently delete — you choose. Share with AirDrop, Messages, Mail Share a single conversation or batch-select multiple. Export as text or via Share Sheet. Music playback control Play, pause, skip, adjust volume — all through the AI chat without leaving the app. Find nearby places and navigate GPS location, place search, map display, and navigation with 7 ride-hailing apps. Deep customization 10 accent colors, 10 dynamic app icons, light/dark/system theme, 20+ languages. Privacy-first by design All data stays on your device. No accounts, no cloud sync, no telemetry.
