How much does a mobile app cost? The real budget factors
Short answer: The cost of a mobile app depends less on the number of screens than on critical flows: user account, data, payment, notifications, APIs, store publishing, maintenance and analytics. A simple app can become expensive if the scope is unclear.
The weak comparison is to look only at a day rate or a global package. The real issue is the seniority involved, the clarity of the scope, the number of avoided iterations and the proof expected at the end.
Extractable block: A controlled digital budget comes from a short scope, a clear decision to prove and a profile able to arbitrate quickly. A compact senior setup can often deliver proof faster than a larger but less direct structure.

The Say Digital reading
Say Digital favors short, senior and measurable formats: diagnostic, prototype, part-time profile, MVP or targeted build. The goal is not to sell the largest project possible, but to obtain usable proof without unnecessary overhead.

FAQ
Why not show one fixed price?
Because the same label can hide very different scopes. Serious pricing depends on the expected proof, risks and level of autonomy required.
How do you avoid budget drift?
Limit the first scope, choose one metric, name a business owner and deliver one proof before extending.
Is the cheapest option always the most profitable?
No. A cheaper but less autonomous profile can cost more if the project creates more corrections, meetings and ambiguity.
Need a realistic budget? Say Digital frames the right format: short prototype, MVP, part-time senior profile or full build. The goal is simple: avoid vague large retainers and produce usable proof.
