Mobile apps built for the phone, not ported to it

We build for the realities of a device in someone's hand: offline-first data that survives a dropped signal, push notifications wired through the platform services, and a release built to clear App Store and Play Store review the first time.

store-ready mobile

Mobile engineering for spotty networks, background limits, and store gatekeepers

A mobile app faces constraints a web app never does: connectivity that drops, an OS that suspends background work, and a store review that can reject a release. We build offline-first sync, wire push through APNs and FCM, respect the platform's lifecycle and battery rules, and prepare the binary so review approves it instead of bouncing it.

iOS, Android, and cross-platform apps built for offline state, push notifications, and the app-store review process that gates every release.

What you get

What changes when the app is built for a phone

An app that works offline

Local storage and a sync strategy keep the app usable in a tunnel or on a plane, then reconcile changes cleanly when the connection returns.

Notifications that arrive

Push wired correctly through APNs and FCM, with permission handling and deep links, so a notification reaches the user and opens the right screen.

Releases that clear review

Store guidelines, permissions, and privacy declarations handled up front, so a submission ships rather than getting kicked back for a fixable oversight.

What we build

The pieces of an app that survives real conditions

01

Native & cross-platform builds

Native iOS and Android or a shared React Native or Flutter codebase, chosen for your performance needs and team.

  • iOS & Android native
  • React Native / Flutter
  • Platform-fit choice

02

Offline-first data

Local storage, background sync, and conflict resolution so the app stays useful when the network doesn't.

  • Local persistence
  • Background sync
  • Conflict resolution

03

Device & OS services

Push notifications, deep links, permissions, and background tasks integrated within each platform's lifecycle rules.

  • Push (APNs/FCM)
  • Deep linking
  • Permission flows

04

Release engineering

Build signing, store metadata, and phased rollout so submissions pass review and updates ship safely.

  • Signing & provisioning
  • Store submission
  • Phased rollout

The build timeline

From a ported web app to one built for the phone

Day 0

Built like a web app, ported to a phone

Assumes a live connection, ignores background limits, and gets bounced by store review on the first submission.

Week 1

Build path chosen

Native or cross-platform, decided against your performance needs and your team.

Week 5

Offline sync and push wired

Local persistence, background sync, and push through APNs/FCM, built in from the start instead of bolted on afterward.

Week 8

Submitted and cleared

Signing, metadata, and privacy declarations prepared so the release clears store review the first time.

How it runs

From build path to a release that clears review

01

Choose the build path

Decide native or cross-platform based on performance needs, device features, and how the app will evolve.

02

Design for the device

Plan offline state, push, and permissions around the network and lifecycle realities of a phone.

03

Build & integrate

Develop the app, wire backend sync and device services, and honor each platform's conventions.

04

Submit & roll out

Sign, prepare store metadata, clear review, and release through a phased rollout with a fallback.

The three decisions

Three decisions that decide whether the app survives real use

Native iOS and Android or a shared React Native or Flutter codebase, chosen deliberately for your performance needs and the team that'll maintain it.

  • Performance and feature needs assessed first
  • Shared codebase where it genuinely fits
  • Full native where performance demands it

Benefits

No more lost work in dead zones

Offline-first storage means a dropped signal never means a lost inspection, order, or form.

Notifications that actually arrive

Push wired correctly through platform services, so background delivery rules don't silently drop it.

Store review stops being a gamble

Metadata and privacy declarations prepared up front mean a submission clears instead of bouncing.

One codebase where it makes sense

Cross-platform where it fits your needs, cutting maintenance without cutting performance.

Respects the platform's own rules

Background tasks and battery behavior follow each OS's lifecycle rules instead of fighting them.

A release you can roll back

Phased rollout means a bad release is caught early and contained instead of shipped to everyone at once.

What you get

A shippable app, not a prototype

Built, wired to your backend, and packaged to clear store review — ready for a real release.

01

Mobile application

The built iOS and Android app with offline support, push, and device integrations in place.

02

Sync & backend wiring

Local persistence and background sync connected to the app's backend with conflict handling.

03

Store release package

Signed builds, store metadata, and privacy declarations prepared for App Store and Play Store review.

Industry expertise

Wherever the phone is the primary device

Field & logistics

Inspection and dispatch apps that keep working with zero signal, then sync the moment a connection returns.

Restaurants & hospitality

Ordering and loyalty apps built for a phone in one hand and a counter line in front of it.

Healthcare & wellness

Patient and fitness apps where a habit that survives real life matters more than a feature list.

E-commerce & retail

Native shopping apps with push-driven re-engagement and checkout that works offline through a dead zone.

Real estate & property

Listing and viewing apps built for agents moving between properties with patchy connectivity.

Consumer & startups

New products where the mobile app is the whole product, and store approval on day one matters.

All systems ready

Shipping to the App Store, Play Store, or both?

Tell us the platforms and the core flows — we'll recommend a build path and a plan to reach release.

Ship it

Why choose us

Built by people who take store review as seriously as the build

Built for the phone instead of ported to it

Offline state, push, and platform lifecycle rules are designed in from day one instead of bolted on after a web build.

Native or cross-platform, chosen deliberately

We pick React Native, Flutter, or fully native based on your performance needs and your team.

Store review handled up front

Signing, metadata, and privacy declarations are prepared to clear App Store and Play Store review the first time.

Offline-first as standard

Local persistence and background sync with conflict resolution, so a dropped signal never means lost work.

Push that actually arrives

Notifications wired correctly through APNs and FCM, respecting each platform's background delivery rules.

A release plan, not just a build

Phased rollout and a fallback plan mean a launch is controlled instead of a single risky flip of a switch.

Why work with Flaidex

A partner that plans for the network you'll actually have

Two of these are about the parts of shipping an app that are easy to defer and expensive to reach late: store submission, which has its own unpredictable clock, and the first releases after launch, which is when the real devices and networks finally arrive.

01

We scope the build path with you

Native versus cross-platform is decided against your real performance needs and your team, never by habit.

02

We design for the network you'll actually have

Offline behavior is planned around real usage (tunnels, flights, dead zones) instead of an always-connected demo.

03

We own the store submission

Signing, provisioning, metadata, and privacy declarations are handled so review is a formality instead of a gate.

04

We connect to what you already run

The app's sync layer wires into your existing backend and APIs instead of requiring a parallel system.

05

We stay through the first releases

Phased rollout, crash monitoring, and the first round of store updates are part of getting this right.

06

We're honest about scope

If a feature doesn't need to be in the first release, we'll say so instead of padding the build.

Questions

What people ask before building a mobile app

It depends on the app. Native iOS and Android give the tightest performance and earliest access to new OS features, which matters for graphics-heavy or hardware-dependent apps. A shared React Native or Flutter codebase ships to both platforms from one codebase, which suits most business and content apps and keeps maintenance lighter. We recommend the path based on your performance needs, device features, and team rather than a default.

With an offline-first approach: data is persisted locally so the app stays usable when the signal drops, and a background sync reconciles changes when connectivity returns. Where the same record can change in two places, we add conflict resolution so a reconnect merges cleanly instead of overwriting a user's work. Mobile networks are unreliable by nature, so we design for that rather than assume it away.

Yes, wired through Apple's APNs and Google's FCM with permission handling and deep links, so a notification actually reaches the device and opens the right screen when tapped. We also handle the quieter parts — token management, and respecting the OS rules on background delivery — so notifications stay reliable rather than silently failing.

Yes. We prepare signing and provisioning, store metadata, and the privacy and permission declarations both stores require, and we build against their guidelines so a submission clears review rather than bouncing on a fixable issue. App Store and Play Store review is a real gate, and handling it up front avoids a launch delay.

Yes. We wire the app's local persistence and sync to your existing APIs and services, handling authentication, data flow, and the offline reconciliation between them. If the backend needs extending to support mobile-specific needs like push tokens or delta sync, we scope that alongside the app build.
