Web & Mobile App Development

One team, one codebase discipline, shipping to browser and app store together.

Timeline
12–16 weeks
Model
Fixed-scope phases

Aksh designs and ships production web and mobile applications from one team. Web work runs on Next.js and TypeScript; mobile ships to iOS and Android from a single React Native codebase. Every build targets sub-2.5 second LCP, WCAG 2.2 AA accessibility, and automated test coverage above 70 percent. Engagements start with a two-week technical discovery that produces a fixed architecture, scope, and delivery schedule.

Outcomes

What you actually end up with

Stated as results, not activities. An activity list describes what an agency does; an outcome list describes what changes for you.

  • One roadmap across web and mobile instead of two divergent backlogs
  • Core Web Vitals treated as an acceptance criterion, not a cleanup task
  • Accessibility audited against WCAG 2.2 AA before release
  • App Store and Play Store submissions handled, including review responses
  • Design system shipped as code, not as a static file

Process

How we deliver Web & Mobile Apps

What is the Web & Mobile Apps process?

Aksh Intelligence delivers Web & Mobile App Development in 4 stages: Discovery and architecture (Week 1–2), Design system (Week 3–4), Build sprints (Week 5–12), Release and store submission (Week 13–14). Each stage closes with a named deliverable you review before the next one starts, and the schedule is fixed at the end of discovery rather than estimated at the proposal stage. Scope changes are quoted in writing before any additional work begins.

  1. Week 1–2

    Discovery and architecture

    User flows, platform split, and technical constraints get resolved up front. You leave with wireframes, an architecture plan, and a fixed price for the build.

  2. Week 3–4

    Design system

    We build the component library in code, wired to design tokens, so the interface stays consistent as scope grows and so QA has a single source of truth.

  3. Week 5–12

    Build sprints

    Feature sprints with a live preview URL per pull request. Performance and accessibility budgets run in CI, so regressions fail the build rather than reaching production.

  4. Week 13–14

    Release and store submission

    Production deploy, App Store and Play Store submission, crash reporting, and analytics instrumentation, followed by a 30-day stabilisation window.

Answers

Web & Mobile Apps questions

Each answer is written to be correct when read on its own — the requirement for snippet extraction and AI citation alike.

Should we build native or cross-platform?

Cross-platform React Native is the right default for B2B products where feature parity matters more than platform-specific polish, and it typically cuts mobile build cost by 35 to 45 percent. We recommend native when the product depends on heavy graphics, background hardware access, or platform APIs that lack stable bridges.

Do you work with our existing design team?

Yes. We can take Figma files and implement them faithfully, or run design ourselves. When your team owns design, we ask for a token-level handoff so the coded design system stays in sync rather than drifting after the first release.

How do you keep Core Web Vitals green after launch?

Performance budgets run inside CI, so a pull request that pushes LCP past 2.5 seconds or introduces layout shift fails before merge. We also wire real-user monitoring at launch, because lab scores and field data diverge once real devices and networks are involved.

Can you maintain the app after launch?

Most clients move onto a monthly engineering retainer covering feature work, dependency upgrades, OS-version compatibility, and store resubmissions. It is optional — the handover is designed so an in-house team can take over without us.

Should we build a native app, cross-platform, or a web app?

It depends on whether you genuinely need the device. Background execution, offline operation, hardware sensors or reliable push notifications justify an app. Where none apply, a responsive web product avoids app stores, review cycles and a permanent maintenance obligation entirely, and is usually the cheaper and faster route.

How long does a mobile app take to build?

A focused first release typically runs three to five months including store submission. Cross-platform halves the effort against two native codebases for most business applications. Build store submission into the schedule early rather than treating it as an administrative step, since privacy declarations and permission justifications are the most common cause of rejection.

What are Core Web Vitals and do they matter?

They measure what users feel: how long until main content appears, how quickly the page responds to input, and how much it moves while loading. The ranking effect is modest, but the underlying experience is not. Most problems trace to an unoptimised hero image, excessive JavaScript, or content inserted without reserved space.

Can you work with our existing codebase?

Usually yes, and incremental replacement beats a rewrite in almost every case. An existing system encodes years of undocumented corrections, and a rewrite rediscovers them slowly. Moving one route or feature at a time behind a routing layer lets the old system shrink while the business keeps running.

How do you handle accessibility?

As an engineering requirement from the start rather than an audit before launch. Semantic elements, a heading hierarchy that descends in order, labelled form inputs and visible focus states are free during construction and tedious to retrofit. Most failures originate in design decisions, which is where we check them first.

Do you build offline-capable applications?

Yes, and for anything used outside an office it is a requirement rather than an enhancement. The pattern is optimistic local writes with a queue that drains on reconnection, explicit synchronisation state so users know what is saved, and conflict handling decided deliberately rather than by whichever write arrived last.
