Frequently Asked Questions

Not necessarily. Platforms like Zoho Creator let you build fully functional custom apps using a drag-and-drop interface, visual logic, and AI-assisted development with minimal to no code required. If you do have development experience, you can extend your app further using scripting and APIs.

It depends on complexity. A straightforward app with a few forms and workflows can go from requirements to deployment in days. More complex apps with integrations and multi-user workflows take longer, but using a AI-powered low-code platform like Zoho Creator significantly cuts development time compared to building from scratch.

Launch is the beginning, not the end. Apps need ongoing maintenance, from fixing post-launch bugs to rolling out updates as your business requirements evolve. Most low-code platforms include version control and update tools that make this easier to manage without dedicated IT support.
