I will develop your native android app using kotlin and firebase

No. Some clients come with a full Figma design, others just have an idea in their head. Either way works — if you don't have a design, I'll either build using standard Material Design patterns or point you toward a designer first if your project needs something custom.

That's normal, and it's exactly why I ask you to message me before ordering a package. Send me a rough description of what the app should do, and I'll tell you which tier actually fits — no point paying for Premium if Standard covers it.

Yes. Full source code is included in every package, and it's yours — no licensing fees, no dependency on me to maintain it later.

Yes, app submission is included. You'll need your own Google Play Developer account (Google requires this to be in your name), but I'll handle the technical submission process.

I can do both. If your app needs a custom backend (not just Firebase), let's discuss it before you order — backend work is scoped separately depending on complexity.

Basic includes 2 revisions; Standard and Premium include unlimited revisions during the project. After final delivery, small fixes are usually quick and low-cost — happy to quote those separately rather than making you guess.

Usually within an hour. If I'm mid-project with another client, it might take a bit longer, but I don't leave messages hanging.
