Mobile app trends for 2027: what to plan for now.
The shifts in AI, app store rules and user expectations that will shape the apps businesses build next year, and what each one means in practice.
Most “app trends” lists are wish lists. This one sticks to changes that are already shipping or already scheduled, so you can plan your 2027 roadmap around them. Sources are listed at the end.
1. On-device AI becomes standard
Both major platforms now give developers AI models that run on the phone itself. At WWDC 2026, Apple expanded its Foundation Models framework to accept images as well as text, added a more capable on-device model for its highest-end devices, and introduced Core AI for running custom models locally on Apple silicon. On Android, Gemini Nano is available to apps through Google’s ML Kit GenAI APIs for tasks like summarizing, rewriting and describing images.
What it means: features like summarizing notes, reading a photo of a receipt, or drafting a reply can run privately, offline and without per-request cloud fees. Plan AI features that work on-device first and fall back to the cloud only when needed.
2. Apps become actions for assistants
Assistants are moving from answering questions to doing things inside apps. Apple’s upgraded Siri uses App Intents and Spotlight indexing to decide which apps it can act in, and AI agents across platforms increasingly call app and web APIs to complete multi-step tasks.
What it means: expose your app’s key actions (book, reorder, check status) through App Intents and a clean API. Apps that assistants can’t reach risk being skipped. Our API planning guide covers how to make an API AI-ready.
3. Payments outside the app store, in the US
Following the Epic v. Apple contempt ruling, US developers can link customers to outside payment pages, and as of fall 2026 Apple charges no commission on those purchases while a court decides what rate, if any, it may charge. The Supreme Court is also reviewing the contempt finding this term.
What it means: subscription and service businesses should design flexible checkout flows that can switch between in-app purchase and web payment, and watch the rate decision closely.
4. Android developer verification goes global
Google now requires Android apps on certified devices to come from verified developers. The rule took effect in Brazil, Indonesia, Singapore and Thailand in September 2026 and is scheduled to roll out globally from 2027. Apps from unverified developers will need an advanced sideloading flow with extra steps.
What it means: businesses that distribute Android apps outside Google Play, such as internal field-team apps or dealer apps, should complete developer verification before the global rollout.
5. Age assurance and privacy rules tighten
Several US states, including Utah, Texas and Louisiana, have passed app store age-verification laws, though Texas’s law was blocked by a federal court and litigation continues. In Europe, the EU AI Act’s obligations phase in through 2026 and 2027.
What it means: apps that serve minors or use AI in sensitive decisions need a clear compliance plan. Collect only the data you need, document how AI features work, and use the platforms’ age-signal tools where they apply.
6. A new design language on both platforms
Apple’s Liquid Glass and Google’s Material 3 Expressive refreshed how iOS and Android look and move. Apps that still use older styles now look dated next to system apps.
What it means: budget for a visual refresh if your app hasn’t been updated recently, and test that custom components still feel at home on the latest OS versions.
7. Cross-platform is the default, not the compromise
React Native, Flutter and Kotlin Multiplatform have matured to the point where most business apps can share one codebase across iOS and Android while still using native features, including the new on-device AI frameworks.
What it means: one team can ship to both platforms faster. Go fully native when you need the deepest platform integration or top performance. See native vs cross-platform.
8. Security for the AI era
AI features add new risks, such as prompt injection, where text in a document or web page tries to trick a model into acting against the user. Meanwhile, passkeys are replacing passwords for sign-in on both platforms.
What it means: treat AI output as untrusted, require confirmation before AI takes irreversible actions, and adopt passkeys to cut down on account takeovers and password resets.
9. Web and app work together
Progressive web apps, web checkout and deep links that move people smoothly between the website and the app are blurring the line between the two. Most customers will meet you on the web first.
What it means: plan the website and the app as one product with a shared back end. Read mobile app vs mobile website and our architecture guide.
A 2027 checklist for your app
- Identify one or two AI features that can run on-device.
- Expose key actions through App Intents and a documented API.
- Review your checkout for US web payment options.
- Complete Android developer verification if you distribute outside Google Play.
- Audit data collection, age handling and AI disclosures.
- Plan a design refresh for the latest iOS and Android styles.
- Add passkeys and an AI security review.

Frequently asked questions
What is the biggest mobile app trend for 2027?
On-device AI. Apple and Google both give apps AI models that run on the phone, making private, offline AI features practical for everyday business apps.
Can US apps use payment options outside the App Store?
Yes. US developers can link to outside payment pages, and as of fall 2026 Apple charges no commission on those purchases while a court decides what rate it may charge.
Do I need to verify my Android developer account?
If your app is installed on certified Android devices, yes. Apps distributed through Google Play by verified Play developers are covered; apps distributed outside Play need a verified developer as the requirement rolls out globally from 2027.
Should my next app be cross-platform?
For most business apps, yes. Modern cross-platform frameworks share one codebase across iOS and Android while still reaching native features. Fully native makes sense for the deepest platform integration or peak performance.
