The app works, so why is there still a bill?
It is the most common question after a launch, and it has a specific answer: the app does not change, but everything around it does.
Apple releases a new iOS every September. Google Play enforces target API levels, and apps that fall behind get hidden from new downloads. Every payment gateway, booking system and login provider you connect to updates its API on its own schedule.
So the realistic timeline for an app with no maintenance budget:
0 to 12 months — works fine
12 to 18 months — minor glitches on newer devices
18 to 24 months — push notifications and logins start breaking
24 to 36 months — removed from new downloads on the Play Store
After that it is a rebuild rather than an update, and a rebuild typically costs 3 to 5 times what consistent annual maintenance would have.
The planning rule most developers use is 15 to 20% of the original build cost per year, agreed before launch rather than after the first problem.
