Web Development
Mobile App Development
The right answer when you genuinely need device capabilities or store presence. The wrong answer when a website would have done, which is more often than it is admitted.
Mobile app development builds iOS and Android applications, native or cross-platform. The Nexclick will ask first whether a progressive web app would do, because an app carries store review, install friction and two codebases to maintain — costs worth paying only when the requirement needs them.
Is this you?
What usually prompts the call
- You need device capabilities the web cannot reach — Bluetooth, background location, health data.
- Your users are field staff who need genuinely reliable offline operation.
- App store presence is how your customers actually expect to find you.
- You have an app nobody maintains and it is falling behind OS releases.
What we do
The actual deliverables
Things that appear on an invoice, not adjectives.
- Challenge the requirement first
- Which device capabilities are genuinely needed. A large share of app briefs describe something a progressive web app does for a fraction of the cost, and we would rather say so.
- Native or cross-platform, argued
- React Native or Flutter for most business apps; fully native where performance or deep integration demands it. The trade-offs are stated rather than assumed.
- Offline-first architecture
- Local storage, sync and conflict resolution designed from the start. Mobile connections are unreliable, and retrofitting offline is close to a rewrite.
- Platform conventions respected
- Navigation, back behaviour, system controls and permissions handled per platform, so the app does not feel foreign on either.
- App store submission and release
- Store listings, screenshots, privacy declarations, review handling and phased release. First submissions are frequently rejected, and it is usually predictable.
- Crash reporting and analytics
- Configured before launch, because you cannot debug a crash on a device you do not have from a report you never received.
- Update and OS-version discipline
- A plan for annual OS releases and store policy changes. Apps do not stay working without maintenance in a way websites broadly do.
Checklist
Before commissioning an app, answer these
Most abandoned apps failed one of these before a line of code was written. Work through them honestly — several point toward a cheaper answer that would have worked.
- 01Which device capability does this need that a website genuinely cannot reach?
- 02Would people use this weekly, or once and then forget it exists?
- 03How will anyone find out the app exists? Store search alone is not a strategy.
- 04What is the reason someone installs it rather than using your website?
- 05Does it need to work offline, genuinely, or is that aspirational?
- 06Who will respond to app store reviews?
- 07Who will submit the update when iOS or Android releases a new version?
- 08What is the budget for the year after launch, not just the build?
- 09Do you have developer accounts, and who owns them?
- 10What personal data does it collect, and can you complete the store privacy declarations?
- 11Does it need to work on older OS versions, and how far back?
- 12What happens to a user’s data if they delete the app?
- 13Is there a web equivalent, and will the two need to stay in sync?
- 14Would a progressive web app do everything on this list except store presence?
How it works
Step by step, with timeframes
Timeframes are typical rather than guaranteed, and they assume we get account access and approvals when we ask.
- 01Week 1–2
Validate the requirement
Whether an app is genuinely needed and which capabilities drive that. An honest gate, and one that has redirected clients to a PWA.
- 02Week 2–6
Architecture and design
Offline strategy, API contracts, platform approach, and interface design for both platforms.
- 03Week 6–18
Build
Increments with TestFlight and Play internal testing builds, so real people use it long before release.
- 04Week 18–22
Submit and release
Store listings, privacy declarations, review handling and a phased rollout with crash monitoring.
What you get
Reporting and ownership
- A written assessment of whether an app is genuinely needed before any build is quoted.
- Offline-first architecture designed at the start, not retrofitted.
- Store submission handled, including privacy declarations and review responses.
- Crash reporting configured before launch, so you learn about failures from data.
- A maintenance plan for annual OS releases, since apps do not stay working unattended.
Tools and platforms
- React Native or Flutter
- Swift / Kotlin where native is required
- TestFlight & Google Play Console
- Crashlytics or Sentry
- Offline sync libraries
- Real device testing across OS versions
Timeline
How long this actually takes
Eighteen to twenty-two weeks including store submission, which itself takes one to three weeks and can be rejected. The ongoing cost is the part most often underestimated: annual iOS and Android releases, store policy changes, and libraries deprecating mean an unmaintained app degrades within eighteen months. Budget for maintenance from the start. And the honest first question stands — if the requirement is content, forms or a dashboard, a progressive web app will cost a fraction and reach everyone immediately.
Pricing model
Project, then retainer
Fixed price against a specification for a defined first version, then a monthly rate for maintenance and OS compatibility. Store developer accounts are yours directly.
Questions
Mobile App Development questions
React Native, Flutter or fully native?
React Native or Flutter for most business apps — one codebase, close to native performance, substantially cheaper. Fully native where you need heavy graphics, deep platform integration, or the absolute best performance. For a typical business app, cross-platform is the right default.
How long does app store approval take?
Usually one to three days for review once submitted, though first submissions are frequently rejected — commonly for privacy declarations, incomplete metadata or a login requirement without a demo account. Allowing one to three weeks for the whole submission process is realistic.
Who owns the developer accounts?
You should, in your business name. Agency-owned developer accounts are a genuine hostage situation, and transferring an app between accounts is possible but tedious. We set this up in your name at the start.
What does it cost to maintain an app?
More than a website, and this is consistently underestimated. Annual iOS and Android releases, store policy changes and library deprecations mean an unmaintained app degrades within about eighteen months. Budget an ongoing amount from the outset rather than treating launch as the end.
How will people find our app?
Not through store search alone, in most cases — the stores are enormously contested and discovery is poor for anything without an existing audience. Apps succeed when you already have customers to tell about it. If discovery is the plan, that plan needs examining before the build.
Should we build a PWA instead?
Quite possibly, and we will tell you. If the requirement is content, forms, dashboards or field tools, a PWA does it for a fraction of the cost with no store review and immediate updates. Native earns its place on deep device integration, heavy graphics, or genuine store discovery.
