Watchkeys: とは？

WatchKeys is a keyboard built specifically for Wear OS smartwatches. Every other Wear OS keyboard covers your full screen while typing, you lose context of what you're replying to, and which app you're in. WatchKeys sits at the bottom, keeping your content visible while you type. Designed specifically for small round watch screens. Each key holds two characters: tap for the first, swipe up for the second. Bigger keys mean fewer misses compared to squeezing 10 keys per row.
