The Call Blocker With 100K Ratings That Nobody Updates

Mr. Number Lookup & Call Block hasn't been updated in 995 days, yet it still pulls in consistent daily downloads. Recent sampled reviewers average 2.7 stars, with nearly 40% of sampled reviewers complaining the app simply stopped working.

The breakdown of 500 sampled reviews shows a product failing at its core promise. Nearly 40% of sampled reviewers report total performance failure, while 28% say the caller ID feature now just returns "personal line" for every incoming number.

The root cause of these failures is total abandonment. At 995 days without a single bug fix or compatibility update, the app's database and iOS integration have completely degraded.

Why are users still downloading an abandoned app?

Mr. Number benefits from the ultimate App Store mirage. The app displays a pristine 4.5-star lifetime average built on nearly 100,000 historical ratings. This massive rating volume keeps it ranking high in search results for utility keywords. Users see the high score and download the app, completely unaware that the developer, Hiya, last shipped an update almost three years ago.

The reality hits immediately upon use. Our analysis of 500 sampled reviews shows the actual current rating is 2.7 stars. That is a massive 1.87-star drop from its lifetime average. Users are walking into a trap, downloading a legacy product that no longer functions on modern iOS versions.

Churn Signal: When an app's core utility relies on an updated database, a 995-day staleness metric means users are highly likely to leave for a competitor within days of downloading.

What exactly is breaking?

When utility apps sit untouched for years, the operating system simply leaves them behind. The data shows exactly how this decay happens. Over 21% of sampled reviewers report that their blocking settings no longer save or function. Another 17% experience constant glitches and freezing just trying to open the app.

The most fatal flaw is the spam detection engine. Exactly 16% of recent reviewers complain that obvious spam calls ring right through. Users who pay for the premium subscription are particularly vocal, noting that the app fails to block spoofed numbers even after manual entry.

Why are paying subscribers leaving?

The frustration multiplies for users who are actively paying for the service. Our monetization analysis shows deeply negative sentiment around the app's subscription model. Users are paying monthly fees for a database that hasn't seen a structural update in nearly three years.

When an app fails to block calls, the subscription feels like a penalty. The data shows that 20% of sampled reviewers specifically cite call blocking failures, noting that even manually blocked numbers continue to ring through. This creates an immediate churn event. Users cancel their subscriptions and head straight to the App Store to leave a 1-star review.

Despite the overwhelming technical decay, about 24% of our sample still praise the legacy spam blocking capabilities. This suggests the underlying demand for the utility remains incredibly high. Users want this specific problem solved, and they are willing to reward an app that actually does it.

How big is the market opportunity?

This is what a textbook market gap looks like. You have a highly visible app pulling in steady organic traffic, but it fails to deliver on its basic premise. The app still generates over 14 reviews per month, which means thousands of users are actively downloading it, getting frustrated, and looking for alternatives.

A disruption score of 65 suggests a prime target for replacement. Breaking down the dimensions, the app scores a massive 24 out of 25 for user pain and 23 out of 25 for abandonment. The combination of high user pain and total abandonment creates a wide-open lane. A new utility developer could easily target Mr. Number's keywords, offer a modern and stable alternative, and capture this steady stream of frustrated traffic.

Key Takeaways

• Lifetime ratings mask reality. Mr. Number boasts a 4.5-star average, but recent reviews sit at a dismal 2.7 stars.
• Abandonment breaks core features. After 995 days without an update, 28% of sampled reviewers report the caller ID function no longer identifies numbers.
• Traffic outlasts maintenance. Despite the neglect, the app still generates over 14 reviews per month, signaling steady inbound traffic ripe for interception.

App Vulture helps you spot abandoned giants and capture their frustrated users before the competition does.
