FAQ

Questions buyers ask us

Native or cross-platform?

Cross-platform is usually faster and cheaper for most business apps; native wins for heavy device features or top performance. We recommend one after seeing your requirements.

Will you publish the app for us?

Yes. We prepare store listings, handle review feedback and publish under your developer accounts.

Who owns the app and accounts?

You do. Apps are published under your Apple and Google accounts and the code lives in your repositories.

Do you maintain apps after launch?

Yes, through a monthly support plan covering OS updates, fixes and small features.
