Frequently asked questions.
How much does an app cost?
A native iPhone app starts at $6,500, and iPhone + Android starts at $12,000, with a basic backend included. To start with less risk, the app plan + prototype is $750 and is credited if we build the app.
Why native instead of a web app?
A native app (Swift on iPhone, Kotlin on Android) is faster, can work offline, sends push notifications, supports widgets and feels like any app in the store. A web app is cheaper, but it shows.
How much is a custom website?
A website with bookings, forms and an admin panel starts at $3,500. A simple landing page starts at $750, and a bilingual site of about 5 pages starts at $1,500.
How long does it take?
A landing page, 1 week. A bilingual site, 2–3 weeks. A custom website with bookings, 4–6 weeks. A native app, 6–12 weeks depending on scope.
Do I own the code and the domain?
Yes. The code, the domain and the store accounts are yours. If you ever want to move on, I hand everything over.
