App store downloads stalling while AI moves software to the browser — app2web shift, RevenueCat data

Are mobile apps dying? No — but the app-first era is. On August 25, 2026, the signal chain was unmistakable: indie developer Adam Lyttle posted that "App Store sales dropped for the first time in a decade," Pieter Levels (levelsio) quote-tweeted "More apps than ever / Less sales than ever," and RevenueCat CEO Jacob Eiting ended his data thread with "app2web is happening." Downloads are flat, App Store growth is single-digit, and most users download zero apps a month. For most businesses, the answer to "should I build an app or a website in 2026?" is: build web-first, add an AI layer, and skip the store tax.

The short answer: should my business build an app or a website in 2026?

Build the website (or web app) first — unless offline access, device-hardware access, or daily-habit re-engagement is core to your product. The data now favors the web on almost every axis of the old app-vs-website debate: cost, speed to launch, discoverability, and — new in 2026 — reachability by AI agents. Native still earns its cost for offline-first tools, hardware-dependent apps, and store-discovery go-to-markets; everything else should ship web-first.

The data behind the app-to-web shift

Downloads have stalled

Total iOS + Google Play downloads hit roughly 150 billion in 2025 — up just +0.8% YoY, per Sensor Tower's State of Mobile 2026. Time spent grew (+3.8% to 5.3T hours) and IAP revenue rose to $167B (+10.6%), but the market stopped adding users. Gaming saw a third straight year of revenue growth while installs actually declined — a shift from new-user volume to lifetime value.[1]

App Store growth is single-digit — and the US just turned negative

BofA (citing Sensor Tower) put Apple App Store revenue growth at 3.7% YoY in Q3 FY2026, versus ~14% expected for Apple's Services segment — the store is the laggard in the services story.[15] Eiting's thread called it the "first decrease in 'App Store' revenue in history in the US. (includes games)."[a] Sensor Tower's Q2 2026 data shows US in-app purchase revenue down 3% YoY to $14.8B; Appfigures (via the Financial Times) reports US App Store commission revenue down 18% since the start of 2026 as developers route purchases off the store.[c][e]

The whole story is gaming vs. non-gaming

Eiting keeps perspective: "Non-gaming (apps) is still up 14.6% YoY globally. Gaming down 4.5%."[a] Sensor Tower's Q2 2026 index confirms it: non-gaming apps generated $24.4B and 25.5B downloads; gaming generated $19.2B and 11.3B, falling below $20B for the first time in nine quarters.[b][d] Eiting himself pushes back: "I'd hesitate to cherry pick this one data point to fit the 'end of apps' narrative."[a] The end of gaming-driven store growth is real. The end of apps is not.

Most users stopped downloading

comScore found that most US smartphone owners download zero apps in a typical month — only about a third download any at all.[5] "App fatigue" is an established pattern, and when most people download nothing, store-first economics change.[12]

The only growth is AI — and AI's main surface is the web

Generative-AI app downloads doubled to 3.8 billion in 2025; GenAI in-app purchases nearly tripled to over $5B; time spent hit 48B hours, ~3.6x 2024.[1] The fastest-growing category in the store is AI — and AI's dominant surface is the browser, not the store.

What is the app-to-web shift (app2web)?

App2web is the movement of software and revenue from native app stores to the open web — checkout, distribution, platform software, and now AI interfaces. It is measurable: RevenueCat data shows web share of revenue rose 31% in a year, from 20% to 26% — "So app2web is happening," per Eiting.[a] The acceleration is US-led: web share of NEW revenue jumped from 5.6% to 11.9% YoY (2025Q2 vs 2026Q2) — more than double — while the rest of the world stayed flat at ~5%.[f]

Signal 1: App-to-web checkout

In August 2026, Apple proposed commissions up to 15% on purchases made via external links in iOS apps (5% small business, 10% subscriptions, 15% standard) — taxing the off-store checkout it must allow after the Epic-ruling injunction effective April 2025.[7][c] RevenueCat even maintains an "App-to-Web Purchase Guidelines" playbook for routing checkout off-store.[6] One developer under the thread: "Lots of big apps have added web funnels."[g]

Signal 2: MCP Apps — the new App Store inside AI chat

On January 26, 2026, Anthropic and OpenAI simultaneously announced MCP Apps — interactive interfaces that render inside Claude and ChatGPT. Figma, Asana, and Slack shipped within 48 hours. WorkOS: "The app directories in Claude and ChatGPT are the new App Store."[2] App2web in its purest form: the app store moving into the browser and the AI assistant. (Our MCP 2026 post covers the change.)

Signal 3: AI labs ship browser-first

OpenAI shipped ChatGPT Atlas — a browser with ChatGPT built in and native agent mode — while Anthropic shipped Claude in Chrome.[8][14] Two opposite bets on one idea: the browser is the AI surface. When platform vendors bet the browser, "build native first" fights the industry's direction.

Signal 4: Platform software moves to the web

Microsoft is retiring Teams-based agent creation in Copilot Studio on June 30, 2026, moving it to the web experience.[10] Platform software moving app → web at Microsoft scale is app2web in real time.

Signal 5: The web closed the feature gap

iOS progressive web apps have had push since iOS 16.4 (March 2023) — the last big capability gap largely closed.[4] Web apps are installable, indexable by Google, and — critically — reachable by AI agents; native app content generally isn't, without a parallel marketing site.[4]

App vs website: the 2026 decision framework

Here's the mobile app vs web app comparison in one table, plus the decision rule that follows. The web wins on cost (one codebase, no store fees), speed to launch, and discovery — indexable by Google and readable by AI agents. Native wins for offline-first products, hardware access, and push-critical re-engagement.[4][9]

CriterionWebsite / web appNative mobile app

OfflineLimited (PWA caching)Full
Hardware accessPartialFull (camera, GPS, sensors)
Store commissionNone15–30%
AI-agent reachDirectIndirect (via marketing site)

The decision rule. If the web app vs native app debate is stalling your team, run three questions: (1) Must it work fully offline? (2) Must it access device hardware? (3) Is daily-habit re-engagement the core metric? 0–1 yes → build web-first. 2–3 yes → evaluate native — ship a web presence alongside either way.[4][9] Unclear on cost? An AI automation ROI analysis settles it faster than a prototype.

What the app-to-web shift means for AI agencies and websites

Websites are becoming AI interfaces. Agents browse, extract, and act on web content; answer engines quote it. That makes answer-engine optimization (AEO) and structured answers more valuable than app-store presence — exactly what an AI automation agency sells.

Web-based AI tools are the growth lane. MCP Apps are a mostly-empty new app store inside ChatGPT and Claude; first movers claim categories now.[2]

Your client's next "app" should probably be a web app with an AI layer. Same product, no store tax, AI-reachable, one codebase. Agencies are repositioning accordingly: web-first builds, MCP/AI integrations, agent-readiness audits — not two-platform native apps. Compare with building in-house if you're weighing it.

Cost expectations matter. RevenueCat's 12,000-user experiment found a web purchase button nets 93¢ per $1 of in-app-only revenue — a conversion trade-off, not free money.[h] And the supply side of "more apps than ever" is AI: SOSA 2026 counts ~15,000 new subscription apps launching monthly versus ~2,000 three years ago — "AI removed a decade old supply constraint on apps."[i]

FAQ

Are mobile apps dying in 2026?

No — but app-first software is losing to the web. Downloads are nearly flat (≈150B, +0.8% YoY),[1] App Store growth is single-digit,[15] and most users download zero apps a month.[5] Non-gaming apps still grew 14.6% YoY; the decline is concentrated in gaming and the US.[a][b]

What is the app-to-web shift (app2web)?

App2web is the movement of software and revenue from native app stores to the open web — across checkout, platform software, and AI interfaces. RevenueCat measured web share of its platform revenue rising from 20% to 26% in a year: "app2web is happening."[a]

Should my business build an app or a website in 2026?

Build web-first unless offline access, hardware access, or daily-habit engagement is core — then native earns its cost. The 0–1 vs 2–3 question rule above settles it in about a minute.[4][9]

Are web apps cheaper than mobile apps?

Yes. One codebase, no store fees, no two-platform maintenance, and no 15–30% commission on revenue.[4]

Can a website do everything an app can?

Mostly. Push arrived with iOS 16.4+, installability and offline come from PWA features — in the web app vs native app matchup, hardware access remains the native edge.[4]

What are MCP apps (apps inside ChatGPT and Claude)?

Interactive interfaces rendered inside AI assistants, announced simultaneously by Anthropic and OpenAI on January 26, 2026 — "the new App Store," per WorkOS.[2]

How much does it cost to build an app vs a website in 2026?

A web app delivers most of the value at a fraction of native cost — two codebases, store fees, and per-platform maintenance are the difference. Run the numbers with an ROI analysis first.

Why are AI tools web-based?

No install friction, instant updates, agent-reachable content, no store commission. ChatGPT Atlas and Claude in Chrome are the two biggest bets that the browser is the AI surface.[8][14]

The bottom line

The app-to-web shift is measurable and concentrated where it hurts: US App Store revenue declined for the first time,[a] commission revenue is down 18% since January,[c] and the fastest-growing software category — AI — lives on the web.[1] Mobile isn't dying; the app-first era is. For businesses deciding app vs website in 2026, the answer is web-first: add an AI layer and keep the store tax out of your margins.
