Mobile App Cost Calculator — FAQs
Why is the range so wide?
App cost is scope × rate. The same app is £15k offshore vs £60k+ with a UK agency — you trade price for timezone, quality control and accountability.
Native or cross-platform?
Cross-platform (React Native/Flutter) covers both stores at ~1.25× a single-platform cost; fully native is ~2×. Only go native for heavy graphics/performance needs.
What's the 15% ongoing?
OS updates, SDK deprecation, bug fixes and minor improvements — typically 15–20% of build cost per year.
