FAQ
Do I need to contact you before ordering?
Yes, please! Every app is different. A quick message lets us confirm scope, features and timeline so you get an accurate quote and delivery date. Orders placed without prior contact may need to be adjusted or cancelled if the scope doesn't match the package
What do you need from me to start?
A clear description of your app idea, the main features you need, and any design references or examples you like. If you have logos, branding or existing accounts (Apple Developer, Google Play), great — if not, I'll guide you through everything step by step.
Do you provide the source code?
Yes. Source code is included in the Standard and Premium packages, and available as an extra on Basic. You get full ownership of the code — clean, documented and ready for any developer to maintain or extend.
Can you publish my app to the App Store and Play Store?
Yes! Store submission is included in the Premium package and available as an extra on other packages. You'll need your own developer accounts (Apple: $99/year, Google: $25 one-time) — I'll handle the entire technical process for you.
Do you offer support after delivery?
Every delivery includes the revisions of your package plus bug fixes for issues found within 7 days. For ongoing maintenance, updates or new features after that, I offer separate arrangements — just message me and we'll set it up.
