Watch any app's reviews — and catch the market opening
Track any App Store or Google Play app, yours or a competitor's, and get told when new low ratings arrive. No store login, because the reviews we read are already public on the store page.

Two reasons to watch a review feed
The defensive one
Your own app breaks after a release. You want to know within a day, in the language the complaint was written in — not at the end of the month, averaged into a number that hides it.
The interesting one
You watch apps you do not own. When a popular app collects the same complaint week after week, that is unmet demand piling up in public — the earliest signal there is that a market has room for somebody else.
Signals that a market is opening
None of these show up in a single star rating. All of them show up in the reviews.
- 1-star reviews rising while the app keeps shipping nothing new
- The same missing feature asked for again and again
- Developer replies drying up on Google Play
- Versions going stale between complaints
- One country turning negative while the global rating looks fine
The last one matters most. An app can be loved in the United States and hated in Germany, and a single global rating hides it completely. We keep the country and the language of every review, so the gap is visible instead of averaged away.
Monitoring, in full
A daily refresh
Both stores, every day, on every app you track. New reviews land in the same table you were already reading.
Alerts you can narrow
Filter by star rating, by keyword, or by language, so an alert means something rather than arriving every hour.
Slack, Telegram, Discord
Delivered where you already work. Alerts also collect on your workspace, so nothing is lost if a channel is muted.
Developer replies kept
Google Play replies stay attached to the review they answer — the clearest sign of whether an incumbent still shows up.
Every market, not one
About 155 App Store storefronts and 28 Google Play languages, with the country and language kept on every review.
One app, both stores
Link the two listings once. They feed the same table, the same alerts and the same export — not two things sharing a name.
We store what was said, never who said it — no reviewer names in the app, the alerts or the export.
An alert tells you something happened. It does not tell you what to do.
One review is an event. The archive behind it is a decision: every country, every language, searchable, with the complaint themes grouped and an opportunity score on the app.
What it costs

Frequently asked
Do I need access to the app to monitor it?
No. Every review we read is already public on the store page. There is no store login, no developer console, and nothing private involved — which is why you can watch a competitor as easily as your own app.
How fast will I hear about a bad review?
Tracked apps refresh daily on both stores, and an alert fires as soon as a matching review appears in that refresh. You can narrow alerts to a star rating, a keyword or a language so the ones you get are worth reading.
Do you store who wrote the review?
No. We keep what was said, never who said it. Reviewer names are not stored, not shown in alerts and not included in any export.
What does monitoring cost?
Monitoring is one credit per app per month. Browsing, filtering, search, charts and export never cost credits, and every new account starts with 5 free credits and no card.
