Will our app meet accessibility requirements?

Yes. We work to WCAG 2.2 AA, the standard most often used to judge ADA compliance in the US, and test with keyboards and screen readers before launch.

How do you handle security for financial products?

We build with encryption, strict access controls and audit trails, and follow standards such as PCI DSS and SOC 2 practices.

Should we build native or cross-platform?

Most business apps work best in React Native or Flutter. We recommend native Swift or Kotlin when you need heavy device features or top performance.

How much does a mobile app cost?

It depends on features, platforms and integrations. Send the form and we'll reply with a clear budget range.

Do you publish the app and support it after launch?

Yes. We handle App Store and Google Play submission and offer ongoing updates and support.
