FAQ
Do you build apps for both Android and iOS?
Yes, I use Flutter to build cross-platform apps that work on both Android and iOS from a single codebase. I also have experience with Native Android development using Kotlin and Java if you need a platform-specific app.
Do I need to provide a design, or can you design the app too?
If you have a Figma file, Adobe XD design, or wireframes, I'll convert them into a fully functional app. If you don't have a design, I can help create one for an additional fee — please check my "App Design" extra service or message me for details.
Will you help publish my app to the Google Play Store or App Store?
Yes, app submission is available as an add-on. I can guide you through the entire publishing process, including account setup, compliance requirements, and final submission.
Do you provide the source code after project completion?
Source code is available as an add-on service. Once selected, you'll receive the complete, well-commented codebase after final delivery.
What do you need from me to get started?
Ideally, I'll need your app requirements or design file (Figma/XD), any API documentation (if applicable), and details about specific features you want included. Feel free to message me before ordering so we can align on scope and timeline.
