What does it cost to have an app built?
The honest answer is: it depends on what it must do. But a few factors determine most of the price.
The number of screens
Every screen has to be designed, built, tested and maintained. An app with five screens costs a fraction of one with forty.
User accounts
The moment people have to log in, everything gets heavier: registration, forgotten passwords, permissions, personal data. It is the most underestimated threshold.
Integrations
An app connected to your existing system needs work on both sides. That part is often larger than the app itself.
Offline and notifications
Two features that sound obvious and are not. Ask yourself whether you genuinely need them.
What comes after
An app is not finished on delivery. Budget annually for operating-system updates, or it will stop working within two years.
