Building apps and websites in Singapore
codigeeks.com is an independent library for people in Singapore who are about to commission, build or maintain an app or a website. It explains what the work involves, which rules apply and which questions to settle before money changes hands. It does not sell development work, and nothing here is a sales page.

What changed in 2026
Three changes from this year affect anyone with an app or a grant application in progress:
- Apple now accepts uploads to App Store Connect only when they are built with Xcode 26 or later against the matching SDKs. The rule has applied since 28 April 2026, according to Apple’s list of upcoming requirements.
- From 31 August 2026, new Android apps and app updates on Google Play must target Android 16 (API level 36) or higher. See Google’s target API level page.
- GoBusiness states that EDG, MRA and PSG under Enterprise Singapore ceased on 29 September 2026, and that business grant support is applied for under the EDGE Grant from 30 September. Older articles that describe PSG as open are out of date. See the GoBusiness PSG page.
How these pages are written
Every rule, fee and deadline on this site links to the authority that publishes it: Apple, Google, the PDPC, IRAS, IPOS, GoBusiness and others. Each page shows when it was last checked. Where a figure depends on your project, such as a build cost, the page explains what drives it rather than inventing a number. Some pages here revisit topics that earlier pages at the same addresses covered. Those topics were written again from scratch for this site.
