How Much Does an App Really Cost? The Cost Structure Behind the Quote

App development quotes on the market run anywhere from NT$500,000 to NT$5,000,000 (≈US$16K–160K) — and every vendor can justify their number. This piece isn't about who's right or wrong; it's about the cost structure behind the quote. Understand it, and you'll know what you're actually buying.

App money goes to three places

1. Frontend: native or cross-platform

Writing separate native apps for iOS and Android means feeding two engineering teams — costs double outright. A cross-platform approach (we use Capacitor ourselves) ships one codebase to both stores at roughly 50–60% of dual-native cost. The trade-off is a ceiling in extreme performance scenarios (heavy games, real-time video processing), but for the vast majority of business apps — membership, booking, content, e-commerce — cross-platform is more than enough. Our own products reached the App Store and Google Play exactly this way; the field notes are in our Capacitor experience write-up.

2. Backend: invisible, and the most expensive part

The app is just the shell; data, accounts, push notifications, and payments all live in the backend. An app that "looks simple" can cost more on the backend than the front. Subscriptions and in-app purchases especially: Apple's and Google's receipt validation, renewal events, and refund handling are all hard server-side work — get it wrong and you either fail to collect money or collect too much.

3. Launch and operations: the long tail people forget to count

Apple review back-and-forth, privacy policies, compatibility updates for every annual OS release, certificate renewals. An app doesn't end at launch — launch is when the monthly bills begin. The developer account's annual fee is pocket change; ongoing maintenance engineering hours are the real cost.

So how much, actually?

Honest ranges from our experience (varies with scope):

• MVP tier (single core feature, cross-platform, basic backend): roughly NT$800K–1.5M
• Full business app (membership, payments or IAP, push, admin panel): roughly NT$1.5M–3M
• Platform tier (multiple roles, complex integrations, high concurrency): NT$3M and up, quoted by scope

If someone quotes NT$500K for a full app with backend and in-app purchases, ask them to itemize the backend spec and the testing scope. Usually they can't — or once they do, the price is no longer NT$500K.

The biggest trap in app pricing isn't expensive — it's cheap: a cheap quote usually only prices "getting it built," not "keeping it alive."

The right way to save money

Don't cut the price — cut the scope. Build only what you can't launch without in version one, then let real user behavior decide version two. We've seen too many projects bet the whole budget on v1 and have nothing left to iterate with after launch — feature-complete, and unused.

One more honest suggestion: ask yourself first, "does this really need to be an app?" Many needs are solved by a mobile website or even LINE, at an order of magnitude lower cost.
