Question 1

What is custom mobile app development?

Accepted Answer

Building an iOS and/or Android app tailored to a specific product and backend, instead of configuring a no-code builder or template. It covers the native-vs-cross-platform architecture decision, the UI build, the API and backend it talks to, device integrations like push notifications or hardware access, and the app store submission process, as one engineering effort, not a series of disconnected vendors.

Question 2

When do you need a custom app instead of a no-code builder or a PWA?

Accepted Answer

A PWA or no-code builder covers you when the app is mostly displaying content or a simple form, doesn't need offline access, and doesn't need anything from the device beyond what a browser can offer. You need a custom build once any of that breaks: real hardware access (Bluetooth, camera, sensors), offline-first data sync, push notifications that actually work reliably on iOS, or a user experience that has to match platform conventions instead of feeling like a wrapped website.

Question 3

We've been debating React Native vs. Flutter internally for weeks. How do you actually decide?

Accepted Answer

That's usually the wrong debate. The real question is native vs. cross-platform, decided by whether the app needs deep hardware access or is mostly API-driven. Once that's answered, React Native vs. Flutter comes down to your team's existing skills — JavaScript/TypeScript or Dart — not an open-ended framework merits debate.

Question 4

Native, cross-platform, or a PWA — how do the trade-offs break down?

Accepted Answer

PWA: fastest and cheapest to ship, but limited push notification reliability on iOS and no real hardware access — fine for content apps, wrong for anything device-dependent. Cross-platform (React Native/Flutter): one codebase for iOS and Android, covers roughly 80% of product needs, meaningfully cheaper than dual native. Native (Swift/Kotlin): required when the app needs deep hardware integration, sustained 60fps graphics, or platform extensions like CarPlay or watchOS — not a style preference, a constraint the other two options can't fully hide.

Question 5

How do you handle offline sync and data consistency?

Accepted Answer

Local-first storage on the device so the app works with no connection, a queue of unsynced changes, and a conflict-resolution strategy decided upfront — last-write-wins, merge, or user-resolved, depending on what the data actually represents. Getting this wrong shows up as duplicated records or silently dropped writes months after launch, which is why the sync strategy is scoped during architecture, not mid-build.

Question 6

How do you architect push notifications reliably?

Accepted Answer

Platform-specific from the start: APNs for iOS, FCM for Android, with a server-side service that tracks device tokens, handles token rotation and expiry, and retries delivery instead of firing once and assuming it landed. Reliability problems with push notifications are almost always a token-management or retry-logic gap on the backend, not the notification service itself.

Question 7

What if we already built on the wrong framework — can that be fixed without a full rebuild?

Accepted Answer

Usually yes for the API and business-logic layer, which is framework-agnostic in most well-structured apps. It's the UI layer that typically needs rebuilding once a wrong platform choice hits a real hardware or performance limit. We scope that specifically instead of defaulting to a full rebuild.

Question 8

Do you still build new apps on Xamarin or Ionic?

Accepted Answer

No. Both are past their growth curve as of 2026, and starting a new project on either creates a harder migration later. If you have an existing Xamarin or Ionic app, that's a modernization conversation, not a new-build one.

Question 9

How is scope defined before you start, since you don't publish fixed prices?

Accepted Answer

Scope is defined after a diagnostic call: which path (native or cross-platform), what's built, what's excluded, and what happens if requirements change mid-build, before any engagement starts.

Question 10

Do you build AI features into the app?

Accepted Answer

This service covers the application itself: the mobile client, its backend, and its data layer. AI and agent capability is out of scope here; we'll point you to a partner who specializes in it rather than bolt it on.

Question 11

Who owns the code and app store listings when the project is done?

Accepted Answer

You do. Source code and app store developer accounts stay in your name and under your control. We don't publish under our own account or hold the listing hostage.

Question 12

What happens if the app gets rejected by the App Store or Google Play?

Accepted Answer

We handle resubmission. Store review guidelines are part of the QA stage, so most rejections get caught before submission, but if one comes back, fixing and resubmitting is part of the deploy stage, not a separate billable surprise.

Question 13

How do you monitor app crashes and performance after launch?

Accepted Answer

Crash reporting and performance monitoring (crash-free session rate, app start time, API latency from the client) are set up before launch, not added after the first bad review. A rising crash rate or a slow API call from the client gets treated the same way we'd treat a backend incident — with a root cause, not a guess.

Question 14

What actually drives the cost of a mobile app build?

Accepted Answer

Platform count (one platform vs. both), whether offline sync or real-time data is required, how much backend/API work is needed alongside the client, and how deep the hardware integration goes. We size the engagement against those factors after the diagnostic call, not off a rate card.

Question 15

How is this different from hiring a mobile-only freelancer or agency?

Accepted Answer

A mobile-only shop builds the client and hands you an API contract to figure out. We build the mobile client and the backend/database it talks to as one engagement, so the data layer is designed to actually support what the app needs, not reverse-engineered after the fact.

Situation	Likely Solution
React Native vs. Flutter (or native) has been debated internally for weeks with no decision	Architecture — the native-vs-cross-platform decision made upfront, before engineering starts
An existing app is stuck on Xamarin or Ionic, both past their growth curve	Cross-Platform rebuild — one React Native or Flutter codebase across iOS and Android
A web product has a solid backend but no mobile client yet	Engineering — cross-platform UI built against the existing API
A previous build picked the wrong framework and is hitting a real hardware or performance ceiling	Native (Swift or Kotlin) — built where cross-platform can't fully hide the constraint
Offline sync, push notifications, or a hardware integration keeps getting descoped	Architecture — offline/sync strategy and device features scoped before the build
An App Store or Google Play rejection came back with no owner for resubmission	Deploy & Support — review-readiness check and resubmission handled through launch

Before	After
React Native vs. Flutter debated for weeks with no framework decision	Native-vs-cross-platform decided on a diagnostic call, framework follows from that
Mobile client built against whatever API already exists	API contracts and offline/sync strategy scoped before engineering starts
Performance validated only in a simulator	Real-device testing across the OS versions and hardware users actually run
Store rejection is a surprise, unbilled fire drill	Review-readiness checked in QA; resubmission is part of the deploy stage

Criterion	DharmOps	Mobile-only agency	No-code builder
Owns the backend/database the app talks to	Yes, same engagement	No — hands you an API contract	N/A — no custom backend
Native vs. cross-platform decision	Made on a diagnostic call, before scoping	Often sold on the framework the shop specializes in	Fixed to whatever the tool supports
Real hardware access (Bluetooth, CarPlay, sensors)	Supported via native Swift/Kotlin	Varies by shop	Usually not supported
Code and store account ownership	Yours, from day one	Varies by contract	Platform-dependent, sometimes locked in
