Predictive smart keyboard for Apple Watch exercise entry

Hey

The keyboard on the watch is impossible to use, but if the spelling would only work with the names of the machines and equipment. It would save a lot of key presses.

Another thing, which I know is harder to make is if you press let’s say L the only possible next letter is E because it should be legs. You can dim the other letters and then it would be much easier to use the keyboard.
Last thing, and the easiest one if only the spelling and the word suggestion would be only for the machines and equipment again it would be best.
