iOS & Android Game Development for Native Performance

Mobile Game Development covers the full game — concept, core loop, monetization, LiveOps — typically built cross-platform in Unity. This service is the platform-native layer underneath: when a title needs Swift/Metal or Kotlin/Vulkan performance, platform-exclusive APIs, or dual-store submission and ASO handled as two genuinely separate processes rather than one. Most projects use both — Unity for the game, native modules where the platform demands it.

For the large majority of mobile games — hyper-casual through most mid-core titles — Unity cross-platform is the right call and native development would be over-engineering. Native earns its cost for titles pushing graphical or performance limits, needing deep platform-exclusive integration, or where App Store or Play Store featuring criteria specifically reward native-feeling polish. We give a direct recommendation rather than defaulting to the more expensive option.

Cross-platform cost is driven by feature depth, art scope, and the dual-store compliance work. Native development for one platform typically adds 30 to 50% over a cross-platform baseline; native for both platforms independently is scoped as close to two separate builds, which we model against the cross-platform alternative so you can see the trade-off in real numbers before deciding.

Apple’s review is manual and editorial with specific, sometimes subjective rejection patterns around monetization disclosure and content guidelines; Google’s is more automated with a phased rollout and a pre-launch report that surfaces device-specific crashes before full release. Treating them as one submission process is the most common reason indie launches get delayed on one store while the other sails through.

Yes, and the effort depends heavily on how the original was built — a Unity title ports far more cheaply than a fully native Swift/Metal game, which effectively requires a parallel native Android build rather than a port. We audit the existing codebase first and give you an honest estimate rather than assuming the cheap-port scenario applies.

Building both platforms in parallel from day one typically adds only two to four weeks over a single-platform timeline, since most of the work — game logic, content, art — is shared; the addition is platform-specific QA and two submission processes. Porting an already-shipped single-platform title afterward usually takes longer than building both together would have, which is why we recommend deciding the platform strategy before development starts, not after.
