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. 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. 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
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, Firebase Storage, and Cloud Functions for server-side logic. You receive bi-weekly builds (APK for Android, TestFlight for iOS) so you can test the actual app on your phone and give feedback on real functionality — not screenshots.
Week 6–7: QA and Bug Fixing
We test on at least six real devices spanning Android and iOS, perform functional and regression testing, and run the OWASP Mobile Top 10 security checklist on every app before it leaves our hands.
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 review correspondence.
