iOS and Android: Key Differences That Affect Cost
Even when you build one app for both platforms, iOS and Android are not identical. Their design conventions, device ranges and store rules differ, and those differences feed directly into the cost and effort of your project.
Understanding where the two diverge helps you plan a sensible budget and avoid surprises late in delivery.
Where the Platforms Differ
- Devices: Android spans thousands of handsets; iOS covers a much smaller, predictable range.
- Design language: iOS follows Human Interface Guidelines, Android follows Material Design.
- Store rules: Apple's review is stricter and slower than Google's.
- Updates: iOS users adopt new versions quickly; Android adoption is far more fragmented.
Why This Affects the Bill
More devices means more testing. Different design rules mean some screens need platform-specific tweaks. Each store has its own developer account, certificates and submission steps that take time to manage.
How We Keep Costs Sensible
- Agree a target device and OS list up front so testing is bounded.
- Share as much code and design as possible across both.
- Only build platform-specific behaviour where it genuinely improves the experience.
