Mobile app development companies in Singapore: a checked list
Ten Singapore firms that build mobile apps, each checked on 21 October 2026 against ACRA's register and its own website. Alphabetical, no ranking, no payment.
This is a list, not a ranking. It is in alphabetical order, no company paid to be on it, and codigeeks.com has no business relationship with any of them. Each entry says only what we could check: the company’s registration in ACRA’s records and what its own website says it does. Use it to start a shortlist, then do your own checks.
How this list was made
An earlier page at this address, archived in January 2022, named twenty mobile app developers in Singapore. We took the nineteen of them other than the page’s own publisher and checked each one again on 21 October 2026 against three criteria:
- Website: the company’s site loads over HTTPS.
- Service: the site describes mobile app development as a service, with a Singapore presence.
- Registration: ACRA’s open register of entities (updated 14 October 2026) lists a registered entity matching the name the site gives, or the brand name where the site gives none.
Ten met all three. The other nine are not listed because at least one criterion could not be confirmed on that date, for reasons that include sites that did not load and sites that no longer describe app development. That says nothing about the quality or standing of those companies. Records change, so check before you sign: ACRA sells current Business Profiles through Bizfile.

Before you shortlist
A registration and a services page tell you a company exists and what it offers, not how well it delivers. Download apps each firm has built and speak to those clients. Open the store accounts in your own company’s name, and put ownership of the code in writing. The consultancy guide explains both, and the cost article explains how to compare quotes.
