| Tool | Description | Behaviour |
|---|---|---|
| estimate_one_star_cost | Same maths as Revunda's 1-star review cost calculator: estimated 1-star reviews per month by complaint theme (sector shares from the 29,785-review study), money exposure if you give a cost per 1-star, 5-star ratings that offset one 1-star, and 5-star ratings needed to reach a target rating. Sectors: parcels, telecom, taxi, energy, news, betting, travel, streaming, insurance, smarthome, banks, shopping, food, health, other. | Read-only |
| get_app_complaints | Top complaint themes in an app's low-star reviews, with real counts and shares from Revunda's studies, plus a link to the app's Revunda page. Pass an app name (e.g. 'AccuWeather'), an App Store URL or numeric id, a Google Play URL or package name (e.g. 'com.commbank.netbank'), or a Shopify App Store URL or handle (e.g. 'judgeme'). If the app is not covered, returns covered:false and a link to Revunda's free check for any app. | Read-only |
| list_covered_apps | List or search the apps that have complaint data in Revunda's studies. Filter by store, by sector/category (e.g. 'Banks & payments', 'Product reviews') or by a name search. Returns name, store, sample size, top complaint and link. | Read-only |
| what_users_complain_about | How often a complaint theme appears in 1-star reviews overall and by sector, and which apps get it most. App stores themes: login (Login & account access), crash (Crashes & won’t open), slow (Slow, loading & lag), update (Broke after an update), support (Customer service), billing (Charges, fees & refunds), payment (Payment or checkout fails), ux (Redesign & confusing UI), ads (Ads), notif (Notifications & alerts). Shopify App Store themes (market='shopify'): support (Slow or no support), bugs (Bugs & broke the store), billing (Charges & refunds), after_uninstall (Charged after uninstalling/cancelling), price_change (Price increases & plan changes), missing (Missing features & limits), slow (Slow store & app speed), leftover (Code left after uninstall), scam (Called it a scam or misleading), expensive (Too expensive for what it does), hard (Hard to use or set up), lockin (Export, import & migration pain), sync (Sync, orders & inventory errors).
