# The App Store's silent giants: AI assistants reply to almost none of their reviewers > Source: > Published: 2026-06-21 15:22:46+00:00 An App Store rating looks like a verdict. It behaves more like a monument, built over years and slow to move. It says very little about how this month's users feel. I took the 12 most-rated Productivity apps on the US App Store, 32 million ratings between them, and split the headline star into the two numbers it hides: how far recent sentiment has fallen below the lifetime average, and whether the developer replies when users complain. The AI assistants now own this chart, and they reply to almost no one. | App | Lifetime | Recent | Reply share | |---|---|---|---| | ChatGPT | 4.8 | 4.18 | 0% | | Claude | 4.7 | 3.06 | 0% | | Grok | 4.9 | 3.77 | 0% | | Perplexity | 4.8 | 3.60 | 0% | | Google Gemini | 4.7 | 3.65 | 13% | | Dropbox | 4.8 | 2.75 | 58% | | Gmail | 4.7 | 2.40 | 26% | | Google Drive | 4.8 | 3.90 | 23% | | Microsoft Authenticator | 4.7 | 2.18 | 1% | The older tools are the ones still in the trenches: Dropbox answers 58% of recent reviewers, Gmail 26%, Drive 23%. The steepest recent drops belong to Microsoft Authenticator (4.7 to 2.18), Gmail (4.7 to 2.40) and Dropbox (4.8 to 2.75). Plotted on two axes, backlash against response, every app falls into one of four archetypes: Firefighters, Ghost Ships, Complacent Giants and Resilient Leaders. Eight of the twelve are Ghost Ships, taking a recent hit in near silence. Recent reviewers self-select toward the dissatisfied. A person who hits a bug is far more likely to leave a review than a contented one, so a low recent average blends genuine decline with that bias, and this data cannot cleanly separate the two. I tie no drop to a specific app release, because the version data is too sparse to support that claim. The lifetime figure is population truth; the recent figure is a biased sample; I never present one as the other.
