Layout:  Multilingual Keyboard Typing Analysis Tool
ErgoFlow analyzes how your fingers actually move when you type—across multiple languages. It gives you real-time visual feedback, highlighting smooth rolling motions and flagging awkward patterns where one finger is overworked. Instead of guessing whether a layout is “good,” you can see the strain, imbalance, and inefficiencies in your typing. See video.
