There is no single answer to “how much does a mobile app cost?” A simple catalogue app and an enterprise application with multiple user roles are both called apps, but their technical needs are very different. A responsible estimate starts with the product goal, platforms, features, and plan for maintaining the app after launch.
The ranges in this guide are for early budgeting, not Trazmedia’s official price list. The case-study figures are anonymised examples, not published prices. A good vendor should still run a discovery process before presenting a final proposal.
TL;DR — 2026 Price Ranges
| App type | Typical market range (IDR) | Estimated timeline | Typical scope |
|---|---|---|---|
| Simple | Rp30–80 million | 2–3 months | 5–8 screens, one platform, catalogue or basic MVP |
| Medium | Rp80–250 million | 3–6 months | accounts, transactions, notifications, basic dashboard |
| Complex | Rp250 million–1 billion+ | 6–12 months | multi-role, real-time features, many integrations, enterprise needs |
These are broad Indonesian market ranges for an initial conversation. Actual cost changes with design quality, backend complexity, number of platforms, QA, integrations, security, and post-launch support. Developer accounts, servers, maintenance, taxes, and third-party fees may sit outside the build quote.
5 Factors That Determine the Cost
Platform strategy: Android only, iOS only, or both
Android can be an efficient starting point when the main audience uses Android. iOS-only can make sense for a specific segment or a market validation plan. Building both at once expands reach, but also expands testing, publishing, and compatibility work.
Discuss the devices customers actually use rather than trying to support every platform immediately. Think about tablets, minimum OS versions, screen sizes, and accessibility requirements early.
Cross-platform: React Native and Flutter
React Native and Flutter let one codebase serve Android and iOS. Across many projects, this can save roughly 30–50% compared with building two separate native applications, but that is only a planning estimate and depends heavily on scope. Hardware-specific features or extreme animation may still need native code.
React Native is often a practical choice for business apps because of its JavaScript/TypeScript ecosystem and broad talent pool. Flutter is strong for highly custom interfaces and consistent rendering. Choose based on the team, integrations, and performance requirements rather than fashion.
Backend complexity: auth, payments, real time, and integrations
The screens are only the visible part of an app. Login, roles and permissions, payments, data synchronisation, real-time chat, push notifications, reports, and ERP or logistics integrations can add substantial work.
List integrations during discovery. A payment gateway needs success and failure flows plus reconciliation. Authentication needs password recovery and account protection. Real-time features need connection, storage, and unstable-network testing.
Design system: template versus custom
A standard component template can speed up an MVP. A custom design system requires user research, flows, wireframes, visual design, prototypes, empty and error states, and a careful handoff. It costs more, but can reduce user confusion and rework as the product grows.
Make sure estimates cover loading, offline, error, permission, and accessibility states. A design that shows only the ideal screen is not yet a complete product specification.
Backend infrastructure: Firebase, Supabase, or a custom server
Firebase or Supabase can speed up an MVP with ready-made services. A custom server gives more control over architecture, data, and integrations. Both have operating costs: database, storage, bandwidth, monitoring, backups, email, SMS, and other third-party services.
Ask the vendor to explain usage assumptions and cost limits. A system that looks cheap to build can become expensive without quotas, logging, backups, and monitoring.
Native vs Cross-Platform — Which Should You Choose?
| Aspect | Native Android/iOS | Cross-platform (React Native/Flutter) |
|---|---|---|
| Performance | Most direct control; ideal for platform-specific needs | More than adequate for most business apps; extreme features may need native modules |
| Cost | Higher when two platforms are built separately | One codebase can reduce duplicated work and cost |
| Time to market | Longer for a two-platform launch | Usually faster for a cross-platform MVP |
| Talent pool | Requires separate Android and iOS expertise | Teams can share skills and components |
| Device features | Fastest access to each platform API | A library or bridge may be needed for some features |
For most business projects, React Native is a pragmatic option: code can be shared and JavaScript/TypeScript skills are widely available. Native is appropriate for demanding games, intensive video processing, specialist devices, or highly specific performance and integration needs. Consider Flutter when a heavily customised interface is the main priority.
MVP vs Full v1 — Budgeting for a Startup
An MVP is not a bad or half-finished app. It is the smallest version that can test an important assumption with real users. A healthy scope might include 5–8 screens, basic authentication, the core flow, and read-only data when transactions are not yet necessary.
For example, a marketplace does not need loyalty, personalised recommendations, seller chat, and dozens of filters on day one. An MVP can first validate product search, detail pages, and an order request. Measure the behaviour you need to prove, not the number of features you can add.
A full v1 usually needs richer authentication and roles, payments, push notifications, an admin panel, analytics, audit logs, and broader QA. Invest in full v1 when the core flow is validated, compliance requires it, or the business cannot operate with a manual process.
Separate “needed to learn” from “nice to have.” That decision often reduces the initial investment without closing the path to a mature product.
Commonly Forgotten Costs (Hidden Costs)
- Apple Developer Account: approximately US$99 per year, subject to Apple’s policies and pricing.
- Google Play: the Google Play developer account is approximately US$25 as a one-time fee, subject to Google’s policies.
- Server and Firebase: monthly cost depends on users, storage, bandwidth, database use, and add-on services.
- Maintenance: budget roughly 15–20% of build cost per year as a planning reference, not a mandatory rate. It may cover bug fixes, monitoring, dependencies, and small changes.
- OS and device updates: new Android/iOS versions, screen sizes, store policies, and API changes may require testing or adjustments.
- Product operations: support, content, analytics, security, email or SMS, and payment gateway fees are often outside development.
Ask whether the post-launch bug warranty, store publishing, source code, documentation, and admin training are included. A low quote that does not explain these components is not necessarily the cheaper option.
Case Studies (Anonymised)
The following are anonymised examples and ranges based on project patterns, not Trazmedia’s published prices.
Edtech startup: learning MVP
An edtech startup began with one platform, about six main screens, simple login, a content catalogue, basic learning progress, and a light admin panel. With focused design and a managed backend, the development budget sat roughly in the Rp40–75 million range over 2–3 months. Live classes and payments were postponed so the team could validate the core usage first.
Established online store: full v1
An operating retail business needed a catalogue, accounts, cart, payments, notifications, delivery status, promotions, and an operations dashboard. With Android and iOS delivered through a cross-platform approach, a representative budget range was Rp150–300 million over 4–6 months. Logistics and payment integrations required substantial discovery and QA.
Enterprise HRIS: multiple roles
An enterprise needed employee, supervisor, HR, and administrator roles; multi-step approvals; audit logs; reports; and internal-system integrations. A project of this nature may fall in the Rp350–800 million or higher range over roughly 6–12 months. The final figure depends on modules, security, data migration, and integration testing.
How to Screen a Mobile App Vendor
Use this checklist before comparing quotes:
- Ask for mobile app work that was actually released, not only design screenshots or websites.
- Ask who handles discovery, UI/UX, development, QA, DevOps, and project management.
- Confirm that the vendor understands App Store and Google Play publishing, metadata, reviews, and staged releases.
- Request a written scope covering flows, platforms, integrations, acceptance criteria, revisions, timeline, and assumptions.
- Confirm ownership of source code, store accounts, design files, documentation, and data after payment.
- Ask about real-device testing, crash monitoring, backups, and post-launch support.
- Request an explanation of OPEX and who controls infrastructure access.

Mobile App Cost FAQ
What is the minimum cost to build an Android app in Indonesia?
A simple MVP with 5–8 screens and one platform generally starts in the tens of millions of rupiah at a software house. A freelancer may cost less, but you take on more risk around documentation, QA, security, and continuity.
Do we need to build Android and iOS at the same time?
Not necessarily. For the Indonesian market, many businesses start with Android because its market share is larger, then add iOS once product-market fit is clearer. The decision should follow your customer data and product strategy.
React Native or Flutter?
For most business cases, React Native is a pragmatic choice because of its JavaScript/TypeScript base and ecosystem. Flutter may be better for heavily customised UI or very specific rendering and performance requirements.
How long does it take to build an app?
An MVP usually takes 2–3 months, a full v1 around 4–7 months, and an enterprise application around 6–12 months. Scope, decision speed, integrations, QA, and store review all affect the schedule.
Will the app source code belong to me?
At Trazmedia, yes, 100%. Put ownership in the contract, including repository access, store accounts, and documentation. A vendor that refuses to clarify ownership is a red flag.
