How Much Does It Cost to Build a Mobile App?
The “How Much Does It Cost to Build a Mobile App?” tool was a microsite that estimated development cost for a mobile app idea based on a short sequence of questions.
The goal was not to give an exact quote, but to help people reason about scope, platform choices and complexity — and translate that into an approximate budget range.
Problem: Abstract Ideas, Fuzzy Budgets
Many individuals and organisations have app ideas, but struggle with one basic question:
“Roughly how much would it cost to build this?”
Traditional discovery calls often suffer from:
- Unclear scope at the beginning,
- Long email threads or meetings just to gather requirements,
- A big gap between initial expectations and realistic costs.
There was room for a self‑service tool that helped idea owners think through key decisions before talking to a development team.
Solution: Question‑Driven Cost Estimation
The tool guided users through a series of visual questions, such as:
- Which platforms do you target? (iOS, Android, both)
- Will users log in? If yes, how?
- Do you need user profiles?
- How will the app generate revenue?
- Is there rating / review functionality?
- Do you need integration with an existing website or backend?
- What level of UX and visual polish do you expect?
- Do you need support for app icon design?
Behind the scenes:
- Each answer had a weight or multiplier,
- The base cost was adjusted according to complexity and integrations,
- The result was presented as a range, not a fixed price.
Approach: Visual Choices, Lightweight Backend
On the frontend:
- Each question was represented as a set of icon‑driven cards,
- Short, non‑technical explanations described what each choice meant,
- The flow was optimised for mobile and quick completion.
On the backend:
- A small PHP application processed the answers,
- The pricing model was kept in a configuration layer,
- The result page summarised selected options and the estimated range.
The experience was designed as an expectation‑setting tool, not a replacement for detailed scoping.
Outcome
With this microsite:
- Idea owners gained a more realistic sense of budget before any call,
- Early conversations between client and agency could focus on the product,
- The same flow could be reused and adjusted as pricing models evolved.
It is a good example of how an interactive content piece can support pre‑sales, discovery and education at the same time.
