Convert Website to App Cost: One-Time Fee vs. Subscriptions

The Three Tiers of Conversion Costs

When you look to convert a website into an app, the cost is determined by the delivery model. You are generally choosing between three paths: the DIY subscription, the licensed wrapper, and the one-time professional build. Understanding the long-term financial implications of these models is essential for any founder managing a budget.

1. The DIY Subscription Model

Services like BuildNatively offer a low barrier to entry. Their Starter tier begins at $19 per month, which totals $228 per year. While this appears affordable, it is a rental model. If you stop paying the monthly fee, your app typically ceases to function or is removed from the stores. Furthermore, you rarely receive the underlying source code, meaning you are locked into their ecosystem indefinitely. Over a three-year period, you will have spent $684 without owning a single line of the code that powers your mobile presence.

2. The Licensed Wrapper Model

Median.co (formerly GoNative) represents the licensed approach. Their Starter package costs $229 as a one-time activation fee. However, this is not a "buy it and own it" deal in the traditional sense. After the first 12 months, there is a recurring annual fee of $179 to maintain the license and receive updates. While you have more control than a pure subscription, you still do not own the full intellectual property of the bridge between your web app and the native hardware. If you stop paying the annual maintenance, you lose access to critical updates required by new iOS and Android versions.

3. The One-Time Professional Build

This is where KW Native operates. Instead of a subscription, you pay a single fee · £399 for Starter (iOS), £599 for Standard (iOS + Android), or £899 for Pro. The critical difference here is ownership. You receive the GitHub repository, the source code, and a RUNBOOK.md. There are no "activation fees" or mandatory monthly tolls to keep the app running. This model treats your app as a business asset rather than a recurring liability.

Mandatory Platform Fees

Regardless of which service you use, you must account for the fees charged by the platform owners. These are paid directly to Apple and Google, not to your conversion partner.

• Apple Developer Program: $99 per year (£79 in the UK). This is required to list apps on the App Store and must be renewed annually to keep your apps live.
• Google Play Console: $25 one-time fee. This allows you to publish unlimited apps to the Google Play Store for life.

At KW Native, we always publish the app under your own developer accounts. This ensures that you, the founder, maintain 100% control over your brand, customer data, and store listing metadata.

Hidden Costs: Maintenance and Updates

The initial cost to convert a website into an app is only half the story. The "hidden" cost often lies in maintenance. Mobile operating systems (iOS and Android) update annually, often introducing breaking changes to how WebViews or native plugins operate.

• Subscription services include these updates in their monthly fee, but the trade-off is that you never stop paying. If their service goes down, your app goes down.
• KW Native provides an optional £199/year maintenance retainer for those who want peace of mind. However, because you own the source code, you are not forced into this. You could hire a freelancer to perform updates later or handle them yourself using the provided documentation.

Why Ownership Matters for ROI

If you use a service that charges $228 per year, over five years you will spend $1,140 and still own nothing. If the service goes out of business or changes its terms, your investment vanishes. By choosing a native mobile app one-time fee model, your investment is capped. For a web app built on modern tools like Lovable, Bolt, or Bubble, the conversion process is a capital expenditure (CapEx), not an ongoing operating expense (OpEx).

Technical Scope: What Are You Paying For?

A professional conversion isn't just a full-screen browser. To pass Apple's strict review process · specifically Guideline 4.2 regarding minimum functionality · the app must feel native and provide features beyond what a mobile website offers. Every KW Native build includes:

• Native Biometrics: Face ID and Touch ID integration for secure, frictionless logins.
• Push Notifications: Full setup via Firebase Cloud Messaging (FCM) to drive user retention.
• Authentication: Apple Sign In and Google OAuth, which are often required for App Store approval.
• Deep Linking: Universal Links (iOS) and App Links (Android) so web links open directly in your app.
• Hardware Access: Full permissions for camera and microphone, enabling features like profile photo uploads or video chat.
• Over-the-Air Updates: The ability to update your web content instantly without waiting for App Store approval.

We proved this model with Ginza, a social network built on Lovable and Supabase. It shipped to the iOS App Store in three weeks and passed review on the first attempt by leveraging these native features to satisfy Apple's requirements.

Comparing Timelines and Rush Fees

Time is money, especially for founders aiming for a specific launch window.

• Starter Tier: 10 business days.
• Standard Tier: 12 business days.
• Pro Tier: 7 business days (Priority handling).
• Rush Service: For an additional £150, we can deliver the binaries in just 5 business days.

When comparing costs, consider the opportunity cost of a slow launch. A subscription service might get you a "preview" quickly, but getting the final .ipa and .aab files ready for store submission often takes significant manual configuration.

Choosing the Right Path for Your Business

• Choose a subscription if you are testing a concept for 60 days and have no intention of long-term growth or asset ownership.
• Choose a licensed wrapper if you have a large corporate budget and prefer the security of a high-volume provider, despite the lack of source code ownership and the recurring $179/year license fee.
• Choose KW Native if you are a founder who wants to own their assets, avoid monthly "app taxes," and get to market quickly with a professional Capacitor-based build.

If you are ready to move away from the subscription trap and secure your app's future, you can get started with a one-time fee build today. We handle the technical heavy lifting so you can focus on growing your user base.
