We're not here to dunk on prompt-and-pray coding — it's a genuinely good way to feel out an idea fast. The honest problem is what happens next, when "feels out an idea" needs to become "a real app my customers can download from the App Store." That's a different job, and it needs a different kind of build.
You describe what you want, an AI writes code, you look at the result, and you describe what's wrong. Repeat. There's no separate discovery phase, no written requirements, no independent check on whether the output matches what you actually meant — just you, a prompt box, and however many rounds it takes.
If you want to see whether a concept even makes sense before spending real money, an afternoon of prompting a web mockup together is hard to beat. It's cheap, it's immediate, and it doesn't require anyone else's buy-in. That's a real, useful job — it's just not the same job as shipping a business-critical mobile app.
What comes out of a chat-based builder is usually a web app, sometimes wrapped to look installable. The App Store and Google Play have their own review processes, native module requirements, and signing rules that a wrapped website routinely fails.
Requirements live in the chat history, not in a spec. Nobody — including the AI — can tell you definitively whether what shipped actually matches what you asked for three iterations ago.
Push notifications, camera access, biometrics, in-app purchase, background location — these need real native modules and platform-specific configuration a browser-first tool wasn't built to generate correctly.
iOS and Android ship OS updates constantly. Without crash monitoring and a maintenance plan, the app that worked at launch quietly stops working, and you're the one who finds out from a customer complaint.
A prompt tool charges you for access to the tool. All the labor of specifying, testing, iterating, and deciding when it's "done enough" is still yours — full-time, whether you meant to sign up for that or not.
Every "just also add..." nudges the app a little further from anything resembling a plan. Without a locked scope and a real change-request boundary, there's no moment where the goalposts stop moving.
| What you're asking | Vibe coding | Agentic Mobile Apps |
|---|---|---|
| What do I actually get? | A codebase and a chat history you maintain yourself | A published app in the App Store and/or Google Play |
| Who builds it? | You, prompting and debugging in a loop | Specialist agents across discovery, design, engineering, and QA |
| Are requirements written down? | Only in the chat history, informally | Versioned requirements, checked against what shipped |
| Does it reach the app stores? | Rarely — most output is web-based | Submitted to iOS and/or Android for you, platforms you choose |
| Native features (push, camera, IAP)? | Ad hoc, frequently broken | Built in from the base template — day one |
| Over-the-air updates? | Not typically wired up | Every app ships OTA-capable |
| What happens after launch? | Whatever you decide to do about it | Crash monitoring, gated fixes, OS upkeep — a real subscription, not a hope |
| How is scope controlled? | It drifts with every new prompt | Locked at quote acceptance; new asks are a scoped change request |
| How does pricing work? | Pay for the tool; your time is the rest of the cost | A firm price, half to start, half when you approve the real build |
| Who owns it? | You, entirely, including every future decision | You — code and store presence are yours, transferable on request |
"Agentic" gets used loosely enough to mean almost nothing. Here it means something specific: your build runs through distinct phases — intake, discovery, design, engineering, verification, delivery — each handled by a specialist agent working from the outputs of the one before it, against a shared, versioned spec. No single agent is improvising the whole app in one breath. Each one is checked before the next one starts, and the whole run leaves an audit trail of what was decided and why.
If a feature doesn't match what you asked for, that's traceable to a specific requirement, not a shrug. If something needs to change after launch, it goes through the same governed process — not a fresh, unmoored prompt session. That's the actual difference a factory buys you over a chat window: not smarter output in the moment, but a process that still makes sense a year later.
