FlashKey is a custom keyboard designed for fast input and ticket/flash sale scenarios. Whether it’s concert tickets, new iPhone launches, or hot flash sales, you can pre-set your name, ID, address, phone number, and other info—then fill forms instantly at the critical moment, getting ahead and checking out with ease! With an intuitive main app interface, you can easily create, edit, and manage custom keys. In any text input field, insert preset content with one tap—no more repetitive typing. Main Features: • Ticket & Flash Sale Ready: Pre-set your info and fill forms instantly during ticket sales or product launches. No manual typing, higher success rate. • Custom Keys: Freely set title, content, color, size, and corner radius. • Drag-and-Drop Layout: Long-press and rearrange keys in real time to build your own keyboard. • Live Preview: Instantly see how your keyboard looks and behaves. • Quick Input: Tap to insert preset content. • Fast Delete: Tap the delete key to remove 10 characters at once. • Privacy & Permissions: All data is stored locally and shared only on your device. “Allow Full Access” is required for the keyboard extension to read your custom keys; the app does not upload your input to the cloud.

Use Cases: • Ticket sales (concerts, sports events, etc.) • Product launches (new iPhone, flash deals, hot items) • Frequent replies, addresses, signatures • Customer service/sales professionals needing template phrases • Power users who love customizing keyboard appearance and layout Privacy Policy https://www.tigerz.asia/privacy/flashkey.html Terms of Use https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
