Frequently Asked Questions

Although I started out as an individual, I have worked with many fine developers and designers over the years, and I often collaborate with them on projects to ensure quick delivery to my clients. Right now, we are a team of 8-10 people, including developers, designers, and digital marketing experts.

App development is a complex process, but my years of experience ensure that I can complete certain tasks quickly. To answer the question, it takes about 6-8 weeks to develop a common Mobile App. After development, about 1 to 2 more weeks are needed for testing the app to make sure it is ready for production.

Every app development project I take on includes 6 months of free post-launch support. The support only includes bug fixes and regular maintenance updates and no new features. Even after the 6 months are up, you can extend support for another year by paying 20% of the project cost.

Personally, I prefer Flutter or React Native, to develop mobile apps as they speed up the whole development and testing process and also promise great native-like performance. Along with my team, I can also help with native apps for Android (using Kotlin) & iOS (using Swift).

While a full-time position is not currently an option I intend to offer, I am available for onsite work for a short period of time if the situation calls for it and also depending on my availability. If onsite work requires travel and accommodation expenses, these will need to be covered by the client.

In addition to the mobile app development process, I can also help you with web app development and UX/UI design. After the app is live, you can also avail post-launch services like Social Media and Search Engine marketing to ensure that your mobile app reaches its target audience.
