I'm in the 60-70 wpm range and during my search for an app that could improve my typing speed, I came across
keybr.com. The concept seems very efficient. The app is basically doing a very detailed live analysis of single keys and adapts itself very quickly to changes in your skill level, presenting you with lessons that are continuously tailored towards training your currently weakest keys, and all that in levels of proficiency. But, because the app uses made up words for the most part, I'm questioning whether practicing with real words would not be more beneficial for everyday life?
What's your take on it? Does anybody have prolonged experience with keybr?
