The basics

Native or cross-platform app: which is better?

Native apps are built separately for Android and iOS and give the best performance for demanding apps. Most business apps work very well cross-platform; we recommend native only when the app needs it.

We also consider whether you need an app at all. Sometimes a mobile-friendly web app does the job for less.

Pricing

How pricing works

Every project is different, so we do not publish a single price. After a free 30-minute call we send a fixed quote with the scope, milestones and timeline in writing.

Fixed quote, no surprises

Scope, deliverables and price are agreed in writing before any work starts.

Pay by milestone

You pay as each agreed stage is delivered and approved, not everything up front.

What changes the price

The number of pages or features, integrations, content and design work, and the support you need after launch.
