客户常见问答 (FAQ)
- 问：做一个APP要多少钱？ (How much does it cost to build an app?)
- 答：原生 APP 加后台通常 15 万起，复杂平台 30 万以上；用 Flutter 跨端能省 40%–50% 重复开发成本。具体看功能，我们先梳理需求，24 小时内给书面报价，逐模块列明，不先报低价再中途加钱。 A native app with an admin backend usually starts at ¥150,000, and complex platforms can exceed ¥300,000. Flutter can cut duplicated work by 40%–50%. We clarify requirements first and send an itemized written quote within 24 hours, with no low-ball price followed by add-ons.
- 问：APP定制开发多久能上线？ (How long does custom app development take before launch?)
- 答：参考工期4–8周起，复杂平台一般2–4个月。流程含需求梳理、原型、UI、开发、联调测试和上线部署；业务型MVP常见4–8周，具体以确认后的范围为准。 The reference timeline starts at 4–8 weeks; complex platforms usually take 2–4 months. The process covers requirements, prototypes, UI, development, integration testing and launch. A business MVP commonly takes 4–8 weeks, subject to the confirmed scope.
- 问：Flutter开发和原生APP有什么区别？ (What is the difference between Flutter and native app development?)
- 答：Flutter跨端可省40%–50%重复开发成本，适合一套代码覆盖iOS和Android。但强动画、蓝牙、硬件连接等场景仍可能要原生适配，我们会按实际功能选方案。 Flutter cross-platform development can reduce duplicated development costs by 40%–50% and is suitable for covering iOS and Android with one codebase. However, heavy animation, Bluetooth and hardware features may still need native adaptation, so we choose based on actual needs.
- 问：开发APP前我需要准备什么？ (What do I need to prepare before app development?)
- 答：建议先用自己的实名注册Apple开发者账号，年费99美元；服务器、域名等也建议用贵司主体注册。业务上先准备核心流程、角色和上线目标，可先签NDA再沟通细节。 We recommend registering the Apple Developer Account under your own real name; it costs US$99 per year. Servers and domains should also be registered by your company. Prepare the core workflow, user roles and launch goals. We can sign an NDA before detailed discussions.
- 问：APP开发付款方式是怎样的？ (What are the payment terms for app development?)
- 答：按3–4个里程碑付款：需求与原型确认、核心功能开发、联调测试可试用包、验收上线与源码移交。每期看到可验证成果再付下一笔，每周给一个可运行版本。 Payments are split into 3–4 milestones: requirements/prototype confirmation, core feature development, integration testing with a trial build, and acceptance/launch with source code handover. You pay the next installment after verifying deliverables, and we provide a runnable build every week.
- 问：你们团队的技术背景与项目协作方式是怎样的？ (What is your studio team background and collaboration model?)
- 答：宋向荣现任工作室技术负责人，约 9 年经验，曾参与京东、安克相关项目。同事有京东、阿里、百度、小红书的项目经验。方案和上架按书面范围推进，项目完成后将源码交给客户。 Studio Tech Lead Song Xiangrong directly leads architecture and communication, backed by senior engineers from JD.com, Alibaba, Baidu, and Xiaohongshu.
- 问：蓝牙硬件通信和商城 IM 能在一个 APP 里一起做吗？ (Can you combine BLE hardware control, e-commerce, and IM chat in one app?)
- 答：可以。我可从架构阶段统一规划蓝牙通信、用户体系、商城支付与 IM 模块，并负责硬件协议联调、后端接口及 APP 双端上架。 Yes. I have shipped apps combining BLE hardware control, real-time IM, and in-app commerce under a unified modular architecture.
