FAQ
Do I own the source code?
Yes. You get full source code ownership upon delivery. No licenses, no hidden fees, no restrictions. The code is yours to modify, extend, or resell as you wish.
Can you publish the app to App Store and Play Store?
Yes. I handle the full publishing process including screenshots, descriptions, and compliance. You only need to create the developer accounts if you don't have them yet.
How do we communicate during the project?
Daily updates via Fiverr chat. For Standard and Premium packages, I also do weekly video calls to review progress. You see mockups before I write any code.
Can you work with my existing design?
Yes. I can implement Figma designs pixel-perfect, or create the UI myself based on your requirements and brand. Both options are included in all packages.
What if I need changes after delivery?
I include a 30-day bug-fix guarantee. For new features after delivery, we can set up a maintenance package or you can order a new gig for the additional work.
What do you need from me to get started?
Your app idea, any design references, and your app store developer accounts. If you don't have accounts yet, I guide you through creating them before we start.
