APP Development Services
Sunzom provides Android, iOS and cross-platform APP development. We deliver operable products, not demos: client app, admin console, APIs and data dashboards as one package. Our in-house product lines — cross-border logistics ERP (shopping APP + driver APP), live-streaming guild management and more — run multi-platform in real production.

FAQ
How much does an APP cost?
It depends on scope and platforms: single-platform tools usually start from tens of thousands CNY; a full two-platform product with commerce and payments is typically in the 100K CNY range. We quote item by item from a feature list, with deliverables written into the contract — no low-ball bait pricing.
Cross-platform or native — how to choose?
Cross-platform (uniapp) gives you Android/iOS/H5 fast at lower cost; heavy hardware interaction or extreme performance calls for native parts. We recommend per scenario, never one-size-fits-all.
How long does it take?
Tool-class APPs 4-8 weeks, trading APPs 8-16 weeks, complex systems 3+ months. The schedule goes into the contract after requirements are confirmed, with a demonstrable deliverable at every stage.
What do I need to publish on app stores?
Usually software copyright registration, a business license, and industry-specific qualifications for payments or sensitive categories. We help prepare the materials; we know both Chinese stores and Google Play.
Do I get the source code?
Yes. Source code, API docs and deployment guides are all delivered. You can deploy on your own servers — the code is yours, no vendor lock-in.
How are later changes charged?
New features are quoted per feature point, or covered by an annual support agreement. Our own product lines iterate continuously, so response speed is guaranteed.
