kywrd tracks your keywords on the App Store and Google Play, watches your competitors, and writes the metadata change — title, subtitle, keyword field — built to each store’s actual rules. You approve it. It ships.
Apple ignores your description and reads a hidden keyword field. Google indexes your description and has no keyword field at all. One app, two rulebooks — and most tools make you learn both. kywrd has them encoded, versioned, and dated, and every suggestion it writes is legal in the store it’s written for.

Apple publishes real search popularity. Google publishes nothing — every Play “volume” number you’ve ever seen is a model. kywrd tells you which is which, on every number, every screen. Measured, modeled, or heuristic. If a data point can’t earn a label, it doesn’t ship.

Every morning kywrd reads your ranks, your competitors’ listings, and what changed. When something’s worth doing, it arrives as a finished change with its reasoning attached — “move ‘horoscope’ to your subtitle; repeating it in the keyword field wastes 10 characters Apple already counted.” Accept it or dismiss it. Either way, you never start from a blank field.

“Keep your plants alive” is a nice line that ranks for nothing. Apple indexes your title, subtitle, and keyword field as one set, so moving “plant care” and “watering reminder” into the subtitle frees 29 characters in the keyword field without losing either term — enough for “monstera”, “propagation”, and “repotting”, all three of which your tracked competitors rank for and you do not.

A competitor editing their metadata is the loudest signal in ASO — it tells you exactly which keyword they’re buying into. kywrd diffs every tracked listing daily and tells you what they changed and, more usefully, why.
