Mobile App Development questions.
Native or cross-platform?
For most business apps, React Native or Flutter gives one codebase and near-native performance. We recommend native when the use case needs it.
Will it work on low-end Android phones and weak networks?
Yes. We test on mid-range Android devices and design offline-first where it matters.
Who owns the app store accounts?
You do. Apps are published under your developer accounts.
Can the app share data with our website and ERP?
Yes. Apps run on the same APIs as your website and integrate with ERP, CRM and payments.
Do you maintain apps after launch?
Yes. OS updates, crash fixes and new releases are covered in the growth pod or a support plan.
Do you provide mobile app development in Jaipur and across India?
Yes. Stack18 is headquartered in Jaipur, Rajasthan, and delivers mobile app development for businesses across India. You get a free 30-minute call, a fixed-price first step and working software every week, so the engagement works the same whether you are in Jaipur or elsewhere.
Often combined with.
Most apps need a web counterpart, a backend and sometimes intelligence. Teams combine app work with web development for the website and web app, custom software development for the systems behind the app, or AI product development for smart features. For retail and D2C, Commerce OS already covers storefront, WhatsApp and warehouse operations. See all Stack18 services.
