Frequently Asked Questions

I provide end-to-end service (Design, Development, Deployment and Maintenance). If you have design mockups or assets, great — I’ll use them. If not, I can design the UI/UX for you (screens, icon, splash screen, etc.) as part of the package.

To get started, I’ll just need a clear description of your app idea or requirements along with your design preferences, such as colors, style, and branding — that’s all.

My pricing depends on factors like number of screens, complexity of functionality, third-party integrations, UI/UX design required, etc.

I provide regular updates (e.g. daily / every few days depending on scope), share prototypes or previews, and you can reach me via Zinn Hub message. I believe in transparency so you always know where the project stands.

Yes, I include app submission services. I can help prepare everything needed for submission, including certificates, store listings, etc.

I offer 90 days free bug-fix support after delivery. For ongoing maintenance, updates, or adding new features later, we can arrange a maintenance plan or hourly work.

Neil and his team were great. It was very evident that Neil knows what he's doing from the very beginning. As I communicated what I envisioned he was able to articulate it back to me better than I was able to explain it. The product he delivered was just what I wanted.

Very impressed

Neil and the team were great at meeting all of my needs for the development of my app. Neil has gone above and beyond to bring my app vision to life. From the start, they have been exceptionally kind, polite, and incredibly responsive, making the entire development process smooth and enjoyable. Their dedication, attention to detail, and willingness to exceed expectations truly set them apart. I’m grateful for their hard work and highly recommend them to anyone looking for a skilled and supportive development team

Neil is ensuring we keep our project on time. He is proactive in his communication.

Neil and his team are amazing
