【Master Your Cursor on iOS】 As a developer, I was frustrated with editing code and managing SSH sessions on my iPhone. The native "magnifying glass" cursor is slow, and my fingers often blocked the text I was trying to select. I built VimKey to scratch my own itch. It brings the precision of desktop editing to your mobile device. Key Features: * Vim-Style Navigation: Use the legendary HJKL (←↓↑→) keys to move the cursor. Keep your hands on the keyboard and fly through text. * Dedicated Arrow Keys: Includes a standard directional pad for precise control without blocking the screen. * Dual Layouts: Seamlessly switch between the navigation layout and a standard QWERTY keyboard (Unlock QWERTY for 30 minutes by watching a short ad, or unlock forever with a one-time purchase). * Privacy First: We respect your data. "Full Access" is requested ONLY to provide haptic feedback and click sounds. We strictly do NOT collect, store, or transmit your keystrokes. Important Note: * Due to browser limitations on iOS, special keys (Esc, Tab, Ctrl) and arrow keys do NOT work in browser-based WebSSH clients. For the best experience, please use a native Terminal app. Contact: I'm actively improving this app based on user feedback. Email: mozhenbear@zodic.dev
