FAQ
1. Can you customize an app built by another developer?
Yes. We provide mobile app customization for existing Flutter and React Native apps on Android and iOS, including projects built by another developer. We first review the source code, dependencies and build setup to confirm which changes are feasible and recommend the right scope for your app.
2. What do you need to review my app and provide a quote?
Share your app link, requested changes, source code availability and any Figma designs or reference apps. API documentation is helpful if integrations are needed. We review your existing mobile app before confirming the scope, milestones, price and delivery. Message us before placing an order.
3. Can you redesign or reskin my app using my branding or Figma files?
Yes. Our app redesign and reskinning services cover colors, logos, splash screens, layouts and navigation. We can implement your Figma designs or plan UI/UX improvements with you. Share your app and brand assets so we can agree on the screens and design changes included in your package.
4. Can you add new features without rebuilding my entire app?
Yes, where your code supports the changes. We can add new features, screens, subscriptions, chat or notifications to your Flutter or React Native app. We assess dependencies and backend needs first, then explain what can be extended and whether any parts need rebuilding before you commit.
5. Can you integrate APIs, payments, AI or connected devices?
Yes. We can add API integration, Firebase, payment gateways, maps, AI chatbots and backend connections to your mobile app. IoT, BLE and NFC features can also be assessed. Share the service documentation and hardware details so we can confirm compatibility, access needs and the agreed scope.
6. Can you customize a purchased template or an app builder project?
Yes, after reviewing the project. For a purchased Flutter or React Native template, share licensed source code and setup details. App builder projects depend on code export and platform limits. We assess whether customization is practical and explain any rebuilding and service costs upfront.
7. How will you test my app after customization?
We test the agreed changes on the Android and iOS platforms included in your order, using real devices and test environments. Testing covers updated screens, integrations and affected user flows. We review related existing behavior and share issues that may need work outside the agreed scope.
8. Will I receive the updated source code, and can you sign an NDA?
Yes. You receive the updated source code for the agreed app customization, with handover details for the changes we deliver. Existing third-party components remain subject to their licenses. We can review and sign an NDA before you share confidential project information, designs or source code.
9. Can you publish the updated app on Google Play and the App Store?
Yes. Google Play and App Store submission support can be included in your app customization quote. You provide your developer accounts, store assets and required information. We prepare the update and help address review feedback related to our changes. Final approval rests with each store.
10. What revisions and support are included with app customization?
Revisions follow your package or custom offer. Bug-fix support for delivered changes lasts 20 days to 3 months, depending on project size; we confirm the period before ordering. New features, additional design changes and unrelated issues are quoted separately. Message us with your app details.
