Frequently asked questions
How much does it cost to build an app?
It depends on complexity and the number of features. We recommend starting with an MVP and growing in stages. We provide a free estimate in US dollars.
Does the app work on both iOS and Android?
Yes. We use cross-platform technology so the same app runs on iOS and Android, reducing cost and time to market.
Can you connect the app to my existing system?
Yes. We integrate apps with existing systems, databases, payment providers and third-party services through APIs.
Shall we start with a diagnosis?
A free first call to understand your business and the problem to solve. We work in English and Spanish with companies in the United States, Canada, Spain, Argentina and Uruguay.
