Frequently asked questions
- General
General
How long does it take to develop an app?
Building an app takes time, and how long it takes depends on how complex it is. Simple apps might be ready in three to six months, but more complicated ones can take much longer. We'll give you a clear timeline once we understand your specific needs.
What technologies do you use for development?
Can you integrate third-party services into my app?
We can connect your software with other services you might use. Need to accept payments? We can integrate payment gateways. Want users to share content on social media? We can add that functionality too. We handle the technical details so your software works seamlessly with other platforms.
Can I see examples of your previous work?
We'll share detailed case studies from our completed projects. Our portfolio includes real examples of successful work, giving you a clear picture of our capabilities and results with previous clients.
What if I want to target multiple platforms?
We build apps that work perfectly on both iPhones and Android phones. You only need one app, and it will reach users on both platforms, saving you time and money.
