An app's cost depends on features, platforms and integrations: a simple MVP costs far less than an app with accounts, payments and a backend. We define the scope with you and give you a fixed written quote — no surprises.
If your goal is to be found and inform, a website is usually more cost-effective. An app makes sense when you need push notifications, frequent use, offline access or device features (camera, GPS). We'll advise you honestly: if you don't need an app, we'll say so.
Yes, we handle everything: developer accounts, store listings, screenshots, reviews and approval. Your app goes live and ready to download.
An MVP is usually ready in 2 to 4 months; a full app with backend and user accounts may take longer. We work in phases with visible deliveries so you see progress from week one.
