What actually drives the price
- Scope: number and complexity of user journeys (not just screens).
- Platforms: one codebase (Flutter/React Native) versus separate native apps.
- Back end: login, roles, database, admin panel, reports.
- Integrations: payments, maps, WhatsApp, SMS, accounting, hardware.
- Compliance: health, finance and children’s data increase effort.
- Who builds it: in-house, freelancer, agency or AI-assisted studio; and where they are located.
Budget bands (indicative)
| Type of app | What it includes | Typical approach |
|---|---|---|
| Simple utility / internal tool | Login, a few screens, one database | No-code, PWA or lean custom build |
| Business process app | Roles, workflows, reports, admin panel, mobile + web | Custom with AI-assisted development |
| Marketplace / on-demand | Two or more user types, payments, maps, notifications | Custom, staged MVP |
| Regulated (health, finance) | Audit logs, consent, encryption, compliance review | Custom with specialist review |
We deliberately do not publish a one-size price table, because misleading ranges cost founders money. Real example: a complete process-automation ERP with a mobile app for a manufacturing plant was delivered for $650.
How AI-accelerated development changes cost
AI coding assistants compress the boilerplate-heavy parts of an app (screens, API clients, CRUD, tests). The savings are real, but only when senior engineers direct the tools, review the output and own architecture and security. That is how a lean studio can ship in days what used to take months, while keeping quality controls.
How to avoid overpaying
- Define the MVP as one user journey and one measurable outcome.
- Ask for a fixed price per milestone, not open-ended hourly billing.
- Insist you own the code, repositories and cloud accounts.
- Reuse proven components (auth, payments, push) instead of custom-building them.
- Plan maintenance: budget a monthly support amount for updates and fixes.
Cost by phase: where the money goes
| Phase | Share of effort | What happens |
|---|---|---|
| Discovery & scoping | 5–10% | User journeys, data model, integrations, success measures |
| Design | 10–15% | Wireframes, UI kit, clickable prototype |
| Development | 40–50% | App, API, admin panel, integrations (AI tools accelerate this most) |
| Testing & fixes | 15–20% | Device testing, security checks, performance |
| Launch & store compliance | 5% | Store listings, privacy forms, review rounds |
| Maintenance (yearly) | 15–20% of build | OS updates, bug fixes, small features, hosting |
These are planning heuristics from typical projects, not quotes. Lean teams with AI-assisted development compress the development and testing share, which is where most of the cost difference between a $650 delivery and a five-figure agency quote comes from. Scope, however, must be equivalent for the comparison to be fair.
Questions to ask before you sign
- What exactly is in version 1, and what is explicitly out?
- Who owns the source code, designs and cloud accounts?
- What does the price include after launch (bugs, hosting, store updates)?
- Can I see a live app you delivered, and speak to that client?
- How will you handle changes to scope: fixed price, or change requests?
Build vs buy: when an off-the-shelf app is enough
If your need is a standard one (appointments, memberships, basic catalogues, simple forms), a configurable SaaS product or a no-code build may be enough and far cheaper. Custom development pays off when your process is unusual, when you need integrations that off-the-shelf tools do not offer, when per-user subscription fees will outgrow a one-time build, or when the app itself is the product.

Frequently asked questions
Why do quotes for the same app differ so much?
Agencies price in overhead, location, process and risk buffers; lean studios using AI-assisted development price in far fewer hours. Compare scope and deliverables, not just totals.
What are the ongoing costs of a mobile app?
Hosting, third-party services (SMS, email, maps, AI APIs), store fees, OS-update compatibility work and support. Plan for a monthly maintenance budget.
Is a cheaper app lower quality?
Not necessarily. Quality depends on scope control, engineering review and testing. Ask to see delivered work and talk to past clients.
Is a PWA cheaper than a native app?
Usually yes, because it is a web app that can be installed on a phone and avoids store review. It has limits on device features and notifications, particularly on iOS, so choose it for simple tools and internal use.
