The Update Treadmill

How much of the App Store is actively maintained, and how big the abandoned tail really is.

Original research by AppWanderer, computed from a sample of 1,043,643 public App Store listings drawn from our index — every figure here is calculated, never estimated. See our editorial standards and glossary.

Summary

Every September iOS changes shape, and apps either scramble to keep up or quietly start falling apart. Honestly, the last-updated date tells you more about an app's health than any marketing page ever will. It doesn't care about feature lists or promises, just whether someone's still bothering to maintain the thing. Looking across 1,043,643 apps with a known update date, the data pushes back against the usual "the App Store is full of dead apps" complaint, though yes, there's still a graveyard sitting out at the edges.

Most of the store is alive

The active core is bigger than the pessimists claim. 12.1% of apps shipped an update in just the last 30 days, and 59.8% were updated within the past year. For all the talk of abandonware, the majority of the store is being actively maintained: patched, adapted to new iPhones, kept current. An app you download today is, more likely than not, one someone is still working on.

And a real graveyard at the edge

But the tail is real. 28.3% of apps have not been touched in over two years, and on a platform that changes annually, that's roughly the point where "still available" stops meaning "still working." A lot of these apps still launch fine, but they fail in quieter ways: logins break, compatibility with the newest iOS slips, security holes just sit there unpatched. They clutter search results and inflate category counts even though they're basically frozen in time. Honestly, a two-year gap without an update is the single clearest red flag on a listing.

How long since the typical app was touched

Look at the timestamps for a second. The median app last got an update 222 days ago, about 7.3 months. Split the store in half and the two sides barely resemble each other: the freshest tenth of apps had been touched within 26 days, while the stalest tenth hadn't seen a release in over 2,179 days, roughly 6 years. Those three numbers alone paint the picture: a sizable core that's actively maintained, and a tail that's basically been left for dead, with not much sitting in between.

That gives you a rough yardstick to use. If the app you're looking at was updated more recently than 7.3 months ago, it's living in the fresher half of the store. If the last update stretches back years, it's fallen into that stale tail, and that's worth questioning before you trust it.

Fresh apps rate better, too

Keeping an app maintained does more than just keep it running. It shows up directly in how much people actually like it. Among apps with real rating volume, the ones updated in the last year average 4.44 stars, while the ones left untouched for over two years average 4.26. That gap looks small at first glance, but on a compressed rating scale it actually counts, and no matter how you slice the data, it points the same direction.

The clearest version of this shows up in the share of apps people genuinely like: 66.1% of recently-updated apps score 4.5 or higher, against just 47.1% of stale ones. Good developers keep shipping, and updates fix the things that annoy people. Both happen together. A recent update date and a high rating tend to go hand in hand.

The apps you have heard of are almost all maintained

Abandonment is really a long tail problem. It barely touches the apps people actually use. Look at the 500 most rated apps in the store, the household names, and 99% of them were updated in the past year. Widen that out to the top 2,000 and the number only slips to 97.5%. Popularity and upkeep move together at the top of the chart. You can't hold onto a huge, active audience without maintaining the app, and that same audience is what funds the maintenance.

That's why the 28.3% stale figure can feel off compared to your own experience. The dead apps are real, they just cluster among obscure titles almost nobody opens. The apps actually competing for attention on the charts and in search are, with very few exceptions, still getting worked on.

Some categories run harder than others

Not every category moves at the same speed. Finance apps (78.4% updated within a year) and Developer Tools keep pushing out updates because they run on live data, servers, and competitors breathing down their necks. Stickers apps (25.2%) sit at the other extreme, where simple tools and reference titles often get left alone once their makers decide they're done. That gap says a lot about how much upkeep a category's apps actually get.

The bottom line

Before you download anything, check the version history date. A few months since the last update? Fine. Within a year? Still normal. Anything past two years, you should treat as abandoned, unless it's a dead-simple tool with no real reason to need maintenance. Skip that exception entirely for apps touching your money, health, or personal data. The store as a whole is active, but the last-updated date is what keeps you out of its dead corners.

What this cannot tell you

Two honest limits. First, an update date records that a release happened, not what it contained: a genuine bug-fix and a token version bump to dodge Apple's "app not updated recently" warning look identical to us, so freshness is a signal of attention, not a guarantee of improvement. Second, "fresh apps rate 4.44 versus 4.26" is a correlation, not proof that updating raises a score โ€” well-run apps tend to do both, and we cannot separate the two here. Every figure โ€” the 222-day median, the 28.3% stale share, the 99% of top apps still maintained โ€” is counted directly across 1,043,643 apps, never modelled.

Method & limitations

How this was made: this study is computed across 1,043,643 apps carrying the public App Store metadata it needs, drawn from our live index of 1,063,421 tracked apps, and is recomputed on a schedule. It is a large, representative sample of the store rather than every app in existence, and the figures shift over time as the store changes.

  • Public metadata only. These figures come from what apps publicly list in the App Store. Downloads, revenue, retention and in-app subscription pricing are not visible to us — we name them, and we never estimate them.
  • A large sample, not a census. The study runs across a representative slice of the store rather than every app in existence, so figures move as the store and our index change.
  • Recomputed, not frozen. Numbers are recalculated on a schedule; a figure quoted elsewhere may differ from the one shown here after the next rebuild.
  • No estimates or third-party numbers are used.

Common questions

How often is the average app updated?

The median app was last updated about 222 days ago, roughly 7.3 months. 12.1% of apps shipped an update in the last 30 days and 59.8% within the past year, so most of the store is actively maintained.

Do apps that get updated more often have better ratings?

They tend to. Apps updated within the last year average 4.44 stars versus 4.26 for apps stale more than two years, and 66.1% of fresh apps score 4.5+ against 47.1% of stale ones.

Are popular apps kept up to date?

Almost always. 99% of the 500 most-rated apps and 97.5% of the top 2,000 were updated in the past year. Abandonment is concentrated in the obscure long tail, not the apps most people actually use.

What counts as an abandoned app?

On iOS, no update in over two years is the practical threshold, because Apple changes the system every year. 28.3% of apps fall into that stale category, and the stalest tenth of the store has gone more than 6 years without a release.
