What determines cost and timeline?
Cost and timeline depend on the number of screens, user login and role structure, payments or subscriptions (StoreKit), maps/location, camera and AI features, push notifications, the need for an admin panel and backend, integration with your existing systems (ERP, POS, CRM), and whether an Android version is wanted at the same time. An MVP-scope iPhone app is usually ready for the App Store within 4–8 weeks.
The quote is a fixed-scope document with every item listed separately. Out-of-scope requests are priced in advance, so there are no surprise costs.
Who hires an iPhone app developer?
Businesses that want to offer customers an ordering, booking or loyalty app; manufacturers that need an inventory, stock count, service or quality control app for field staff; startups going to market with a subscription product; and content- and notification-focused organizations such as associations, foundations and educational institutions.
