APP Development FAQ
Resolving Your Development Concerns
App development costs vary based on functional complexity, design requirements, and technical architecture. We provide transparent, itemized quotes and clearly list the cost range for each functional module in the contract, preventing unexpected additional charges mid-development. We recommend providing a detailed requirements list at the initial consultation. Our project manager can help you prioritize requirements and find the development strategy that best fits your budget.
We provide comprehensive after-sales maintenance. When iOS or Android releases a major update, we proactively assess compatibility impacts and provide solutions. Compatibility fixes during the warranty period are free. After the warranty period, ongoing support can be continued through a long-term maintenance contract.
Generally, a mid-size App (with membership system, payment gateway, and admin panel) takes 3 to 6 months. For rapid launch requirements, we can help plan an MVP (Minimum Viable Product) version, launching with core features first and iterating incrementally — typically completing a basic version within 6 to 8 weeks.
Yes, this is one of our core commitments. All complete source code of the deliverables is handed over to the client upon project completion, along with technical documentation and deployment instructions. We do not use technology to lock in clients, ensuring you have full ownership of your digital assets.
Our development process strictly follows the latest review guidelines from Apple and Google, including privacy policy requirements, permission request descriptions, and content compliance. We conduct a complete pre-review inspection before submission and assist you in preparing all required review documentation. If rejected, we provide free revisions until the app passes.
Absolutely — this is precisely the advantage of our consultancy-style service. Our project managers and business consultants communicate with you in non-technical language, translating your business goals into concrete technical specifications. We provide regular progress reports throughout development, so you can stay fully informed without needing to understand code.
Yes, TWJOIN is ISO 27001 certified for Information Security Management Systems. All development processes adhere to relevant security standards, including code review, vulnerability scanning, and access control mechanisms, ensuring your product and customer data are properly protected.
