Mobile App Development
We build mobile apps people keep on their home screen. One codebase where cross-platform makes sense, fully native where the hardware demands it — and the judgement to tell you which one your product actually needs.
Store submission, review feedback, phased rollouts and crash triage are part of the engagement. The work is not finished when the build compiles; it is finished when your app is live and stable in both stores.
What We Deliver
The work this engagement actually covers — and what you own at the end of it.
Cross-Platform Development
Flutter and React Native apps that share one codebase across iOS and Android, with platform-specific behaviour where users expect it rather than a lowest-common-denominator interface.
Native iOS & Android
Swift and Kotlin builds for products that lean on the camera, Bluetooth, background processing, ARKit or on-device machine learning.
Offline-First Architecture
Local persistence and conflict-aware sync, so the app stays useful on a train, in a warehouse or anywhere the signal drops.
App Store Submission
Store listings, screenshots, privacy declarations and review responses. We have shipped through both review processes often enough to know what gets an app rejected.
Backend & Real-Time Sync
The APIs, push notification infrastructure and real-time channels the app depends on, built by the same team so nobody is stuck integrating across a contract boundary.
Analytics & Crash Reporting
Instrumentation from the first release, so you learn where users drop off and we learn which devices are crashing before your reviews do.
What you receive
- Signed release builds in App Store Connect and Google Play Console
- Source code and build pipelines in your Git organisation
- Store listings, screenshots and privacy declarations
- Crash reporting and analytics wired up and documented
- Device and OS support matrix, tested
- Release runbook for future submissions
How the Work Runs
No stage is a surprise, and every one of them ends in something you can look at.
Platform Strategy
We decide cross-platform versus native on the evidence — your feature set, hardware needs, budget and how you plan to staff maintenance.
Design & Prototype
Interface design against real iOS and Android conventions, then a prototype on a physical device. Screens that feel right in Figma often do not feel right in the hand.
Build & Test
Sprint builds distributed to your team through TestFlight and Play internal testing, on real devices, from the second sprint onward.
Store Submission
Listings, compliance declarations, staged rollout and the review process handled end to end, including replying to reviewer queries.
Monitor & Improve
Crash-free rate, retention and funnel data watched after launch, with fixes shipped on a predictable release cadence.
What Good Looks Like
A cross-platform codebase is the point: two stores, one team, one set of business logic to keep correct — without the sluggish, obviously-not-native feel that gave the approach its old reputation.
Technology We Use

Engagement Models
Three ways to work with us. Which one fits depends on how settled your scope is and how long you need the team.
Fixed-Scope Project
A defined outcome, an agreed timeline
We scope the work up front, agree the deliverables and the date, and carry the delivery risk. Best when you know what you need built and want a predictable commitment.
Best for
- A launch with a hard deadline
- A well-understood rebuild or migration
- First projects with a new partner
What's included
- Written scope, milestones and acceptance criteria
- A named project lead and weekly demos
- Fixed delivery date with change control
- 30 days of complimentary post-launch support
Dedicated Team
Our engineers, your roadmap
A ring-fenced team — engineers, designers and QA — working only on your product, in your rituals and your tools. You set the priorities sprint by sprint.
Best for
- Evolving product roadmaps
- Scaling an in-house team quickly
- Long-running platform work
What's included
- Named team members, not a rotating pool
- Your sprint cadence, standups and board
- Direct access to every engineer on the team
- Scale the team up or down at each sprint boundary
Ongoing Retainer
Someone who already knows your system
A monthly block of engineering time for maintenance, security patching, performance work and steady improvement — from the people who built it.
Best for
- Live products that need care, not a rebuild
- Security and dependency upkeep
- Incremental features after launch
What's included
- Essential, Growth and Enterprise tiers
- Monitoring, security patches and dependency updates
- Agreed response times, up to a 24/7 SLA
- Monthly report on what changed and what it cost
Apps need attention after launch — OS releases, store policy changes, device fragmentation. A retainer usually follows the initial build for that reason.

Mobile Apps Questions
The things prospective clients ask us before committing to this work.
Should we build cross-platform or native?
Cross-platform with Flutter or React Native suits most products: one codebase, both stores, roughly 40% less build and maintenance effort. Go native when the app depends heavily on the camera, AR, Bluetooth peripherals, background processing or on-device ML. Aquison Technologies makes that recommendation during platform strategy, with the reasoning written down.
What is the difference between a PWA and a native mobile app?
A Progressive Web App runs in the browser and can be installed without going through an app store. It offers offline capability and push notifications. A native app is built specifically for iOS or Android using platform SDKs. We recommend PWAs for content-heavy applications and native or cross-platform apps for hardware-intensive features like AR, Bluetooth or advanced camera access.
Do you handle App Store and Google Play submission?
Yes. We prepare the store listings, screenshots, privacy declarations and data-safety forms, submit on your developer accounts, and handle reviewer questions. Straightforward apps typically clear App Store review in under 48 hours; we plan for longer on first submissions and anything involving payments or health data.
How long does it take to build a mobile app?
A focused app with a handful of core flows takes 10–14 weeks including store submission. Apps with real-time sync, payments or complex offline behaviour usually run 4–6 months. You get a milestone plan after platform strategy and design, before the build commitment.
Can you add features to an app we already have in the stores?
Yes, provided we can get a clean look at the codebase first. We start with a technical audit covering dependency health, crash rates and build reproducibility, then work in your existing release cadence. Taking over the developer accounts and signing keys cleanly is part of the onboarding.
