69 Abandoned iOS Apps Are Still Making Money

There's a music app on the App Store right now that hasn't been updated in eight years. Eight. It charges $2.99. It sits at #42 on the paid charts in its category. It has a 2.0-star rating.

We estimate it pulls in around $1,241 per month.

The developer is gone. The reviews are brutal. And nobody (seriously, nobody) has built the alternative. You know what that is? That's twelve hundred dollars a month sitting on the table with no one reaching for it.

When we ran through 982,572 iOS apps, we found 69 that fit this exact pattern. Apps that haven't been updated in at least 2 years but still have users who can't find anything better. And 69 of those are paid apps with actual, verified revenue.

What counts as "abandoned" (and what doesn't)

We didn't just slap a filter on the "last updated" date and call it a day. That would miss the nuance. An app that got a minor bug fix 19 months ago might still be quietly maintained. An app that shipped a big rewrite 2 years ago and still works perfectly? Not really abandoned.

So we look at the full picture:

• Update frequency history. Was this developer shipping monthly, then went completely silent?
• Developer portfolio. Did they abandon all their apps, or just this one?
• Compatibility. Does the app still run on current iOS? A lot of them don't.
• Review trajectory. Are recent reviews getting worse? That's real-time decay.

An app that was last updated in 2019 and is still on the charts? That's not just abandoned. That's proof of demand that outlived its builder. That's the kind of thing that should make you open Xcode.

Why developers walk away from working apps

Here's what's funny. It's almost never because the market dried up. The reasons are way more boring than that:

In every single case, the users get left behind. They're still opening the app. Still leaving reviews. Still hoping someone does something about it.

The reviews tell you everything

Abandoned apps have a very specific review pattern. The older reviews (from when the developer was still around) are mixed. Maybe 3-4 stars. The recent reviews? Almost all 1-star. And they're incredibly specific about what's wrong:

You know what those are? Those are user stories. Written by real people. For free. They're telling you exactly what's broken, exactly what they wish existed, and (in some cases) exactly how much they'd pay. You didn't even have to schedule a user interview.

This is easier than building from scratch

Here's the thing people don't immediately realize: abandoned apps tend to be simpler apps. These aren't social networks or streaming platforms. They're:

• Specialty calculators and unit converters
• Niche reference apps (music theory, knot tying, bird identification)
• Simple productivity tools (habit trackers, timers, grade calculators)
• Education apps for specific subjects or exams
• Utility apps (file converters, QR scanners, measurement tools)

A solo developer can rebuild most of these in SwiftUI over a weekend. Seriously. The original developer probably wrote it in Objective-C back in 2016. You have ten years of platform improvements on your side. SwiftUI, Core ML, modern APIs, all the stuff that makes the rebuild dramatically simpler than the original was.

And your bar for success? Beat 2 stars. That's it. Ship something that works, that doesn't crash on current hardware, that looks like somebody actually designed it this decade. The users are already there, already frustrated, already searching for something better.

69 of them are literally still charging money

This is the part that makes it very concrete: 69 of the abandoned apps we found are paid apps still generating revenue. Real people are spending actual money on software that its developer stopped caring about years ago.

That means the whole "will anyone pay for this?" question is already answered. Yes. They're paying right now. For the broken version.

The highest-earning abandoned app in our dataset pulls in a monthly number that would make most indie developers very happy. And the developer hasn't pushed an update since the first Trump administration. Let that sink in for a second.

How to tell if an abandoned app is worth replacing

Not all of them are. Some are genuinely dead markets. Here's how to separate real opportunities from dead ends:

1. Check the review count. An abandoned app with 50 ratings is a niche inside a niche. One with 5,000+ ratings has serious demand behind it.
2. Read the recent 1-star reviews. Are people complaining about fixable things (crashes, bad UI, missing features)? Or about the core concept itself? Big difference.
3. Search for alternatives. If three well-rated apps already exist in the same niche, someone beat you to it. If the alternatives are also terrible? Green light.
4. Estimate the build. Can you ship an MVP in a weekend? A week? A month? The sweet spot is the apps where modern tools make the rebuild almost embarrassingly easy.
5. Look at the monetization. Is it a paid app? Does the category support paid downloads, or is it all free-with-ads? Your time is worth more than fraction-of-a-cent ad impressions.
