How Much Does It Cost to Build an App?
Every honest answer to "how much does it cost to build an app" starts the same way: it depends on scope. That is not evasion — it is the actual mechanism. This page explains what drives the number, so you can estimate your own project before talking to anyone.
Why nobody can quote you without questions
An app is not a unit of work. "A food delivery app" could mean a menu browser with a contact form, or a real-time dispatch system with driver tracking, payments, and three separate user roles. The first is a few weeks. The second is most of a year. The phrase describes both.
Anyone who quotes a firm price before understanding your scope is either guessing or pricing in a large safety margin. Both cost you money.
What actually drives the number
- Number of user roles
One kind of user is a straightforward build. Add an admin dashboard and you have a second product. Add a third role — driver, vendor, reviewer — and you have three. Roles multiply work faster than features do.
- Backend requirements
An app that stores everything on the device is dramatically cheaper than one needing accounts, sync, and a server. The moment you need "log in on another device and see my data", you have added an entire second system to build and maintain.
- Third-party integrations
Payments, maps, messaging, calendars, health data. Each integration carries its own edge cases, failure modes, and review requirements. Payments in particular add compliance work that is invisible in a feature list.
- Platform count
iOS only is one build. iOS plus Android is not double, but it is well above one — typically 1.4× to 1.8× depending on approach. Add web or desktop and it rises again.
- Design ambition
Standard platform components are fast. Custom animation, bespoke layouts, and a distinctive visual identity are slower and need more iteration.
- Real-time anything
Live tracking, chat, collaborative editing, multiplayer. These change the architecture rather than adding to it, and they are a common source of underestimation.
Realistic ranges by project size
These are broad industry bands for a competent agency build, not a quote. Treat them as a way to locate your project, then get a scoped estimate.
| Size | What it looks like | Typical build |
|---|---|---|
| Simple | Single role, local storage, few screens, no backend | 4–8 weeks |
| Moderate | Accounts, backend sync, one or two integrations, admin view | 3–5 months |
| Complex | Multiple roles, payments, real-time features, multi-platform | 6–12 months |
| Platform | Multi-sided marketplace or system with ongoing operations | 12 months+ |
The costs that get forgotten
Apple Developer Program: an annual fee, required to ship on the App Store at all.
Backend hosting: ongoing and scales with usage. Small at first, not zero.
Third-party services: payment processing takes a percentage; mapping, messaging, and analytics services usually bill per request or per user.
Maintenance: the largest forgotten cost. Operating systems update annually and things break. Budget for it — see app maintenance costs after launch.
Design, if not already done: if you arrive without designs, that work exists and has to happen somewhere.
How to get a cheaper build honestly
The reliable lever is scope, not rate. Cutting the hourly rate while holding scope constant usually buys less experienced people and more rework.
Ship one platform first. Learn what users actually do before paying to build it twice.
Cut the admin panel. Early on, a spreadsheet and a developer with database access does the same job for nothing.
Delay accounts. If the app works without login, launch without it. Accounts pull in a backend, password reset, privacy policy obligations, and support load.
Build the smallest version that proves the idea. See MVP vs full product build.
How we estimate at KIDA Studios
We start with a short discovery conversation to establish roles, data, and integrations — the three things that move the number most. From that we produce a written scope with a range, and the assumptions the range depends on. If the assumptions change, the number changes, and you can see exactly why.
We have shipped six of our own apps across iOS, macOS, watchOS, and Steam, so our estimates come from having carried products through review, launch, and maintenance ourselves rather than from a rate card.
Frequently asked questions
How much does it cost to build an app?
It depends almost entirely on scope. A simple single-role app with no backend is typically a 4-8 week build, a moderate app with accounts and integrations is 3-5 months, and a complex multi-role platform with payments and real-time features runs 6-12 months or more. The number of user roles, whether you need a backend, and how many integrations you require drive the cost more than feature count.
Why won't developers give a fixed price upfront?
Because 'an app' describes wildly different amounts of work. Without knowing user roles, data requirements, and integrations, any fixed number either includes a large risk margin you pay for, or will change later. A short discovery phase produces a far more accurate figure.
Is it cheaper to build for one platform first?
Usually yes. Building iOS and Android together typically costs 1.4-1.8x a single platform. Shipping one first also means you learn what users actually do before paying to build those assumptions twice.
What ongoing costs does an app have after launch?
The Apple Developer Program annual fee, backend hosting if you have a server, per-use fees for third-party services like payments or maps, and maintenance to keep up with annual OS releases. Maintenance is the most commonly forgotten one.
What is the cheapest way to reduce app development cost?
Reduce scope, not rate. Ship one platform, delay user accounts if the app works without them, skip a custom admin panel early on, and build the smallest version that proves the idea works.
