How is your mobile app made?

A jó alkalmazás nem ötletszinten születik – hanem egy átgondolt, lépésről lépésre felépített folyamat eredménye. Mi így dolgozunk Önnel:

01

Developing a strategy

Megértjük az üzleti céljait, feltérképezzük a felhasználókat és a versenytársakat. Ez az alapja annak, hogy ne csak appot, hanem értéket teremtsünk.

02

Clarifying functions and requirements

Workshopok és konzultációk során közösen határozzuk meg, hogy mit tudjon az app – és mi az, ami nem szükséges. Így gyorsabban és pontosabban haladunk.
Design workshopsUI/UX DesignCorporate design

03

UX/UI and prototyping

We create interactive designs (e.g. using Figma) to test how the app will work before development. This reduces errors and speeds up decisions.
BackendSDKAPITech stackFrontend

04

Development (agile or waterfall method)

Attól függően, milyen projektje van, alkalmazkodunk: folyamatos egyeztetés, sprint alapú haladás vagy fix specifikáció. Mindkét esetben Ön végig látja, hol tartunk.
BackendSDKAPITech stackFrontend

05

Testing and bug fixing

Az egyes verziókat már fejlesztés közben is teszteljük, Ön pedig bármikor kipróbálhatja az aktuális állapotot (pl. TestFlight vagy Android OTA). Cél: hibamentes élmény.
StatisticsDevelopment cyclesSupport

06

Start-up, support, further development

Az app elkészülte után sem tűnünk el: segítünk az élesítésben, monitorozzuk a működést, és kérésre új funkciókat is fejlesztünk.
