FAQ
What do you need to get started?
Just your app idea and any references or features in mind. We define the scope together before you order that's why I ask you to message me first.
Do you build native or Flutter apps?
I build with Flutter, so you get one clean codebase for both iOS and Android faster to build, cheaper to maintain, with a native look and feel.
Do you design the app too?
Yes. Design and development come together a professional UI/UX so your app looks as good as it works.
Do you charge upfront?
No. I work in phases and deliver a testable TestFlight build at the end of each one. Fiverr holds the payment and releases it only after you approve.
Will I get the source code?
Yes, full source code is included in the Standard and Premium packages.
Can you publish my app to the App Store?
Yes App Store submission is included in Standard and Premium (you'll need an Apple Developer account), or I can guide you through it.
What if I need changes or a bigger app?
Each package includes revisions and I offer ongoing support. For larger, multi-phase apps I send a custom milestone-based offer.
