The right way to get an iPhone app built in Istanbul
For Istanbul startups preparing to raise funding, speed is everything: an MVP ready in time for the investor pitch and testable with real users. We cut the scope down to the 3–5 most valuable screens, ship weekly builds on TestFlight, release the first version on the App Store and grow it with user data.
For e-commerce and retail brands, an app drives more repeat purchases than a website through push notifications, cart reminders, loyalty points and in-store stock visibility. It connects via API to your existing e-commerce platform and marketplace integrations.
