unitQ analysis: App quality issues up 2.8% after iOS 26 launch

SAN FRANCISCO, Oct. 15, 2025 /PRNewswire/ -- In a unitQ analysis of more than 647,000 app store reviews across 5,043 iOS apps, our proprietary AI detected a 2.8% increase in quality issues — friction — reported by users in the three weeks following the iOS 26 release (Sep 15–Oct 6). That's a modest uptick compared with the dramatic spikes seen after iOS 16 and iOS 17, when user-reported quality issues jumped by double digits. Both iOS 18 and now iOS 26 have shown far more stability, evidence that developers are increasingly using real-time customer feedback to anticipate and address OS-level disruptions before users feel the impact.

The dataset

• Source: App Store reviews parsed and categorized by unitQ's proprietary AI
• Scope: 5,043 unique apps; 647,705 pieces of user feedback
• Window: Pre-release (Aug 25–Sep 14) vs post-release (Sep 15–Oct 6)
• Findings:
  • Quality issues: 110,177 → 113,246 (+2.8%)
  • Feature requests: 2,345 → 2,105 (↓ to 1.8% of total)
  • Overall feedback volume: +2.5%

In raw terms, users reported slightly more friction after upgrading to iOS 26, but nowhere near the volatility of earlier updates like iOS 16 (+42%) and iOS 17 (+29%). The stability observed in iOS 18 (+3%) and now iOS 26 reflects how customer feedback-driven teams are catching and fixing regressions earlier in the rollout cycle. (*Apple jumped its OS version numbering from iOS 18 to iOS 26 this year.)

What users noticed most

• Crashes/force closes: +21.7%
• Slow performance: +23.4%
• Freezing: +33.1%
• Device not compatible: +28.9%
• Notifications not received: +24.7%
• Password not accepted: +41.8%
• Profile photo upload failures: +64.2%

Even as overall disruption was limited, these recurring stability issues show where OS-level changes continue to challenge developers. Minor regressions in login flows, notification delivery and media handling can quickly translate into thousands of frustrated users — and thousands of data points for AI to detect.

Impact by selected app category
unitQ AI detected varying impacts across verticals, revealing how different types of apps responded to the iOS 26 rollout. Some categories saw mild increases, while others remained steady or even improved—an indication that readiness levels and user expectations vary widely across industries.

• Gambling: +15.5% — Noticeable increases in login errors and payment flow instability, indicating that apps in highly regulated categories still face friction adapting to new OS-level security and compliance requirements.
• Business & Productivity: +14.6% — Users noted more login and sync-related friction, often tied to third-party integrations or updated permission frameworks.
• Music: +10.5% — Playback interruptions, missing lyrics and connection issues with smart speakers like Sonos and Alexa drove most of the increase.
• Dating: −5.7% — Minor declines in reported issues suggest stability improvements in core messaging and matching features.
• Photo & Video: −0.2% — Largely steady performance, with small fluctuations in freezing and upload-related feedback.
• Finance: −0.1% — Virtually unchanged, signaling strong pre-release testing among high-compliance apps where reliability is paramount.
• Shopping: −3.0% — A small decline in quality issues, reflecting smoother payment and checkout flows after prior years' post-update turbulence.
• Gaming: −4.2% — Fewer stability reports overall, suggesting developers effectively optimized for new graphics and performance APIs introduced in iOS 26.
• Social Networking: +12.2% — Slight uptick tied to notification delivery and image rendering issues, typical of complex, content-heavy apps.
• Health & Fitness: +1.3% — Largely stable, with some device pairing and activity-tracking anomalies reported early in rollout.
• Travel: −1.8% — Minor declines in location and booking-related complaints, showing incremental progress in handling OS-level map and permission updates.

These results highlight a key trend: Industries that have made consistent investments in monitoring and acting on user feedback are now seeing steadier performance across major OS updates. Verticals like finance, travel and shopping — where reliability and trust are core to the user experience — show that continuous, feedback-driven quality management can all but eliminate the post-release chaos that once followed major iOS upgrades.

Ratings and sentiment

• Average star rating: 3.50 → 3.41

Earlier OS rollouts saw this ratio collapse far more sharply. The modest decline following iOS 26 suggests that developers are resolving emerging issues before negative sentiment compounds.

Why this year's iOS 26 rollout looks different
The rise of real-time Voice-of-the-Customer (VoC) platforms like unitQ has fundamentally changed how teams monitor app quality. Rather than waiting for crash logs or support tickets, developers continuously parse user feedback through platforms like unitQ, which classify and quantify issue trends as they emerge. This feedback loop allows teams to validate fixes faster and ship targeted patches during rollout rather than reacting afterward.

Cross-functional collaboration between product, engineering and support is beginning to center on user signals, not just telemetry. AI-driven tooling such as unitQ automatically identifies new issue types, even when users describe them in inconsistent or novel language — something traditional monitoring systems miss.

While public and developer beta versions of iOS have existed for years, developers are now using those betas far more strategically. Testing is broader, more data-driven and increasingly informed by real-world user behavior. Teams are beginning to instrument beta cycles to collect structured feedback at scale, feeding that data into AI-powered systems like unitQ to identify early signals of breakage, localization issues or UI regressions before general release.

Together, these factors have made OS rollouts like iOS 26 far smoother. Developers aren't seeing fewer problems by chance. They're preventing them through smarter listening, better testing and faster iteration powered by customer feedback. Best of all, these changes are transforming what used to be a reactive scramble after major Apple iOS updates into a data-driven process of continuous tuning.

The bigger takeaway
Every iOS launch is a global stress test for app quality. The modest rise in user-reported issues after iOS 26 shows that teams are adapting — and that customer feedback is central to that evolution.

With unitQ, organizations can aggregate user feedback from every channel in real time, auto-classify issues, quantify impact by cohort or device and detect micro-outages before ratings fall. When the next iOS version arrives, the best-prepared teams will already know where to focus — because their users will have told them first.

Bottom line: Double-digit post-release meltdowns are becoming history. iOS 26 proves that when developers listen to users and act on real-time feedback, app quality can stay steady through even the biggest platform changes. That's the power of unitQ — transforming millions of unfiltered user comments into one actionable view of product quality, so teams can fix issues faster and keep experiences seamless through every update.
