The Question We Get Most Often
Almost every week a founder asks us: "How does this actually work? I have never built an app before. What am I paying for, and what do I get, at each stage?" It is a completely reasonable thing to want to understand. App development is expensive and intangible — you are paying for something that does not exist yet. This post makes the entire process visible and concrete.
Week 0: Discovery Call and Scope Definition (Free)
Before any engagement begins we spend 30–60 minutes on a call to understand your business, your users, and the core problem your app solves. We ask deliberately uncomfortable questions: Why will someone use your app instead of an existing alternative? How do you plan to acquire your first 100 users? What does success look like in 12 months?
After the discovery call we deliver a written scope document within 24 hours: the features included, the features explicitly excluded, a timeline, and a fixed price.
Week 1–2: Design Sprints
Development does not start until you have approved the designs. We use Figma to build interactive prototypes — clickable screens that simulate the app experience without a line of code being written. Design review typically takes two rounds. The approved Figma file becomes the single source of truth that developers build from.
Why does design come first? Because a change to a UI element in Figma takes five minutes. The same change in code takes five hours. Every ambiguity resolved at the design stage saves ten times the time in development.
Week 2–6: Flutter Development
Development follows the designs screen by screen. We structure Flutter projects using a clean architecture pattern — separating the UI layer, business logic, and data layer — which makes the codebase maintainable by any Flutter developer, not just the original author.
We use Firebase for most MVPs: Firestore for the database, Firebase Auth for authentication, Firebase Storage for files, and Cloud Functions for server-side logic. You receive bi-weekly builds so you can use the actual app on your phone and give feedback on real functionality.
Week 6–7: QA and Bug Fixing
Before any app leaves our hands it goes through structured testing: functional testing, regression testing, device testing (at least six real devices spanning Android and iOS), and performance testing. We also run the OWASP Mobile Top 10 security checklist on every app.
Week 7–8: App Store Submission
We have submitted over 30 apps and know exactly what reviewers flag. We handle the entire submission: creating the App Store Connect and Google Play Console listings, writing optimised app descriptions for ASO, uploading screenshots in every required resolution, completing the privacy questionnaire, and managing the review correspondence.
Post-Launch: 30 Days of Free Support
Our 30-day post-launch support window covers any bugs that surface in production — patches, crash fixes, and minor UX adjustments.
