FAQ

Questions you may have about App and mini program development

From selection and timeline to security and operations — all explained at once

App or mini program — how should I choose?

Mini programs suit lightweight, use-and-go scenarios focused on private domain and payment loops; apps suit businesses needing system-level capability, strong experience and user retention. After diagnosis we recommend the best combination, advancing on both platforms when needed.

Does cross-platform development sacrifice experience?

No one-size-fits-all. We use Flutter / React Native for 80% of common UI, while keeping native implementations for core modules sensitive to performance and experience — balancing efficiency and quality.

How are the development timeline and quote calculated?

Timeline depends on feature complexity: mini programs usually take 2-6 weeks, native apps generally 6-12 weeks. Pricing is based on feature modules and the number of platforms, with a clear proposal and quote after a free diagnosis.

Can you do data security and private deployment?

Yes. We support both public-cloud and private deployment, with data encryption, tiered permissions and compliance auditing for strongly regulated industries such as finance and healthcare.

Do you handle operations after launch?

Yes. We provide full-lifecycle operations: monitoring and alerts, hot updates, version iteration and a user-feedback loop, with monthly operations and growth data reports.

Can you embed AI capabilities?

Yes. AI capabilities such as smart recommendations, voice interaction, image recognition and conversational support can be embedded, giving your app / mini program an intelligent AI-era experience.
