How do maintenance and post‑launch support affect app costs?

This is a really important topic – post-launch maintenance and support can often cost as much as the initial development, especially when you factor in updates, security patches, and compatibility changes. Platforms and technologies evolve quickly, so ongoing investment is essential to keep an app functional and secure. Businesses should budget 15–25% of the original development cost annually for maintenance. If you're into app development or tech project management, I've found some useful discussions and resources at slotexos.it/ – might be worth a look for more practical advice.
