FAQ

Mobile app development FAQ

Straight answers on timeline, tech stack, store publishing, pricing, and integrations.

It depends on scope. A simple MVP app (login, listing, forms) often ships in 4–8 weeks; mid-complexity apps with payments, admin panel, and notifications can take 2–4 months. You get a phased plan before development starts.

Both ship Android and iOS from one codebase. Flutter is a strong fit for custom UI, POS-style, and Android-heavy workflows. React Native suits teams already using React on the web. For most Indian SMB operational apps, Flutter is our default.

Yes — store listing, screenshots, description, compliance checks, versioning, and phased rollout are handled by us. After launch, optional AMC covers OS updates, library bumps, and crash monitoring.

Scope drives cost — screens, roles, integrations, payment gateways, and offline use. After a short discovery we share a transparent estimate and milestones — no surprise invoices.

Yes — REST APIs, Firebase, Laravel backends, payment gateways (Razorpay, PhonePe), and third-party SaaS where documented APIs exist. Sync points are designed so data stays consistent.
