Autocomplete is the store's own demand signal — what it suggests is what real users type. The new Autocomplete Simulator (Tools → Autocomplete) puts that signal on screen:
A phone in your dashboard. Pick a store and country, start typing, and a faithful phone mockup — App Store search tab on iOS, Play Store search on Android — fills with the store's live suggestions on every pause, exactly as a user would see them. There's even a store dark-mode toggle.
Suggestions you can act on. Next to the phone, every suggestion comes enriched with the popularity and difficulty Sonar already knows, an iOS suggest-priority column, and a Tracked badge for terms already on your list. Copy a term, export the list, or track any suggestion to one of your products in two clicks.
Click a keyword to see who ranks for it. Any suggestion opens a live results panel — the top 10 apps for that keyword, with the keyword lit up wherever it appears in an app's name or subtitle. One glance tells you how contested the term is and who's titling for it. Apps punching above their weight get an Outlier badge: they hold a top-10 slot with a fraction of the ratings of everyone around them, which usually means they're winning on metadata alone — exactly the listings worth studying.
Then click the app. Any result opens its full store listing right beside the results: rating, price and in-app purchase range, estimated revenue, category, version and update history, size, screenshots, and the complete description with your keyword highlighted throughout — the whole picture of what a ranking listing actually looks like. Found a real rival? Track as competitor adds it to one of your products and kicks off a keyword scan, without leaving the panel.
"When does my keyword appear?" Switch to Keyword reveal mode, enter your target keyword, and Sonar probes how many characters a user has to type before the store starts suggesting it — then replays the typing on the phone so you can watch your keyword surface. If it never shows up by nine characters, that's an honest signal too: the store hasn't learned the term yet.
