Industry benchmarks put average app maintenance at roughly 20% of the original build cost per year. So a £80,000 app means budgeting around £16,000 annually to keep it healthy, secure, and competitive.

Our recent article, Mobile App Maintenance Costs: What Every Business Should Know, covers the full breakdown.
