QuickShare: Transfer, No Ads

QuickShare is a LAN file transfer app with zero ads and zero mobile data. Android, iOS, Windows and macOS — phone to PC, PC to phone, Android to iPhone. No cables, no data usage, no size limit, no quality loss. Files move directly between your devices, never through a server. ⚡ Zero Mobile Data, Full Bandwidth Everything runs over your local network: not a single byte of mobile data is used, and nothing is relayed through a server, so speed depends only on your router. A 1GB video finishes in seconds. No throttling. 🖥️ Four Platforms: Android, iOS, Windows, macOS Android to iPhone, iPhone to Android, phone to PC, PC to phone, Windows to Mac — any two devices can exchange files directly, regardless of OS. One interface everywhere: your phone, your work PC, your Mac, your friend's Android. No cloud drive to install on each platform. 🚫 No Ads. Ever. No splash ads, no interstitials, no recommendation feed, no "watch an ad to unlock speed". QuickShare is ad-free, period. Transfers run entirely on your LAN and use no mobile data — move huge files even when your data plan is nearly gone or you're in airplane mode with Wi-Fi on. Works with the internet off, as long as your LAN is up. 📂 Send Anything, No Compression, No Size Limit Photos, videos, music, documents, archives, whole folders — all formats supported. No ads, no compression, no re-encoding, no per-file size cap: what arrives is exactly what you sent. Select multiple files or entire folders at once. 🔒 Encrypted Transfer with PIN Confirmation Transfers are protected by TLS with RSA 2048 self-signed certificates, and device identity is verified by SHA-256 certificate fingerprint under a TOFU (Trust On First Use) model. Each transfer generates a 6-digit PIN valid for 5 minutes, compared in constant time to resist timing attacks; five failures in a row trigger an exponential lockout. 📁 Received File Manager A built-in list of everything you've received, newest first, filterable by images, videos, audio, documents and archives. Open or share straight from the list. 🕓 Device History Recently connected devices are saved for one-tap reconnect — no rescanning. 🔍 Dual Device Discovery UDP multicast and HTTP active scanning run in parallel to find devices on your LAN. A radar animation shows progress in real time. How to Send: 1. Connect both devices to the same Wi-Fi and open QuickShare. 2. Tap "Send" and pick the target device once the radar scan finishes. 3. Select files or folders, then tap "Send". How to Receive: 1. Connect to the same Wi-Fi as the sender, open QuickShare, tap "Receive". 2. A request appears showing the sender and the file list. 3. Files stream to local storage with real-time progress, then appear under "Received Files".
