How much does it cost to develop a mobile app in Singapore?
What actually drives the price of a mobile app, the fixed store fees you can check, the running costs after launch, and how to get quotes you can compare.
There is no honest single figure for “an app”. Two apps that look alike in the store can differ widely in cost, because much of the work sits where users never see it. Instead of a price list, this article explains what moves the number, which costs are fixed and checkable, and how to get quotes you can compare.
An earlier article at this address listed price ranges by type of app. They are not repeated here: they dated from 2018 and cannot be checked against any current source.
What drives the price
Most of the cost is people’s time, so anything that adds time adds cost:
- Number of screens and states. Every screen needs design, building and testing, including its empty, loading and error states.
- Platforms. iOS and Android each have their own store, rules and testing. Building one codebase for both can save time, but the per-platform work of store rules and testing remains.
- Back end. Accounts, payments, messaging, bookings and admin dashboards all need servers, databases and someone to secure them. An app that only shows information needs far less.
- Integrations. Linking to payment providers, accounting, booking or government services takes time, especially when the other system is old or poorly documented.
- Personal data. If the app handles personal data, the PDPA obligations (consent, protection, retention, breach response) become design and engineering work.
- Design depth. A custom visual identity and user research cost more than adapting standard platform components.
Why types of app differ so much
A content app that shows your menu, catalogue or articles is mostly front end. A shopping app adds a cart, payments, stock and order management. A booking or marketplace app adds two sides (customers and providers), schedules, matching and disputes. A chat or social app adds real-time messaging, moderation and heavy back-end load. Internal business apps can be simple screens over an existing system, or a full replacement of one. Place your idea on that scale before asking for quotes.
The fixed costs you can check
A few costs are set by Apple and Google, not by your developer:
- The Apple Developer Program costs 99 USD per membership year.
- A Google Play Console account has a US$25 one-time registration fee.
Open both in your company’s name.
Running costs after launch
Budget for the years after release, not only the build. Hosting and third-party services bill monthly. And both platforms raise their requirements every year: Apple now requires uploads to be built with Xcode 26 or later, and Google requires new apps and updates to target API level 36 from 31 August 2026. Each change means developer time. The maintenance guide lists the work involved.
Is the quoted price fixed?
That depends on the contract, so ask. A fixed price buys a defined scope: anything outside it becomes a change request with its own price. Time and materials bills the hours actually spent, which suits projects whose scope will move. Some projects mix the two, with a fixed first release and hourly work after it. Whichever you choose, make sure the quote lists what is included, what is excluded, and how changes are priced.
Grants
Older articles often mention the Productivity Solutions Grant. GoBusiness states that EDG, MRA and PSG under Enterprise Singapore ceased on 29 September 2026, with business grant support now applied for under the EDGE Grant. Check whether a specific solution is supported before you budget around it.
Getting comparable quotes
Send every developer the same written brief: users, the main job of the app, screens for the first release, platforms, back-end needs and what is out of scope. Ask each quote to break the work into design, app development, back end, testing and project management, and to state the yearly maintenance cost separately. The consultancy guide covers the rest of the contract.
