Who owns the App Store accounts?

You do. We publish under your developer accounts so you keep control of the listings, reviews and revenue. We'll set them up if you don't have them.

How long does store review take?

Apple typically reviews in 24–48 hours, Google faster. First submissions get rejected more often, so we budget for a round of review feedback in the launch plan.

Can you take over an existing app?

Often, yes. We start with a paid audit of the codebase and give you an honest recommendation — sometimes that recommendation is a rewrite, and we'll explain exactly why.

Mobile App Development

A mobile app is a promise to be available, fast and reliable in someone's pocket. We build apps that keep that promise — including offline, on bad networks, and on four-year-old devices.

Typical duration: 10–20 weeks
Engagement: Team of 3–5 · Fixed scope or retainer
Right for you if: Field teams working where connectivity is unreliable
Products where mobile is the primary surface, not a companion
Companies whose current app has one-star reviews about crashes
Businesses needing device features: camera, location, biometrics, offline

Problems

You're probably here because of one of these.

If more than one sounds familiar, that's normal — they usually share a root cause.

It breaks without signal

Field staff, drivers and technicians lose work when the network drops. Offline has to be designed in, not bolted on.

It feels like a website in a box

Wrong gestures, no haptics, laggy scrolling. Users notice within ten seconds, and the reviews say so.

Every release is a gamble

Manual builds, unpredictable store review, no crash reporting. You find out about bugs from customers.

It drains the battery

Aggressive polling, unbounded background work and chatty analytics get an app uninstalled fast.

Approach

How the work actually runs.

From first conversation to running in production. Typical end-to-end duration for mobile app development is 10–20 weeks.

01
Discovery
1–2 weeks
We map the problem before proposing a solution. Stakeholder interviews, constraint analysis, and a written scope you actually own.
- Stakeholder interviews and workflow mapping
- Technical constraints and integration audit
- Written scope, risks and success metrics
- Fixed-price proposal with a delivery plan
02
Architecture & design
2–3 weeks
System design and interface design happen together, so the thing we draw is the thing we can actually build.
- Platform-specific interaction patterns for iOS and Android
- Offline-first data and sync-conflict strategy
- Navigation architecture and deep-link map
- Device permission and onboarding flows
03
Build
6–12 weeks
Two-week iterations against a shared board. You get a working deployed environment from week one and a demo every sprint.
- Shared codebase with platform-specific native modules where needed
- Local persistence with background sync and conflict resolution
- Push notifications, deep links and biometric authentication
- Automated builds to TestFlight and Play internal testing
04
Hardening
1–2 weeks
Automated test coverage, load testing, accessibility audit and a security review before anything touches production.
- Unit, integration and end-to-end test suites
- Load and performance profiling under realistic traffic
- WCAG 2.2 AA accessibility audit and remediation
- Dependency, authentication and access-control review
05
Launch
1 week
Staged rollout with monitoring in place before traffic arrives. Rollback is tested, not assumed.
- App Store and Play Store submission, assets and copy included
- Staged rollout with crash reporting and performance monitoring
- Store listing optimization and screenshot production
- Release pipeline handed over to your team
06
Operate
Ongoing
We stay on. Response-time SLAs, proactive dependency upgrades, and a roadmap review every quarter.
- Uptime, error and performance monitoring with alerting
- Defined severity levels and response-time commitments
- Scheduled dependency and security patching
- Quarterly roadmap and architecture review

Included

What you get, spelled out.

Every item here is part of the engagement, not an upsell discovered halfway through.

Offline-first architecture

The app works with no connection and reconciles cleanly when signal returns.

One codebase, two platforms

Shared logic with native modules where the platform genuinely differs — not lowest-common-denominator UI.

Push notifications

Segmented, deep-linked and permission-respectful. Notifications that don't get your app muted.

Biometric authentication

Face ID and fingerprint with secure keychain storage and a sensible fallback.

Crash and performance monitoring

You learn about problems from your dashboard, not your reviews.

Automated release pipeline

Tagged commits build, sign and ship to TestFlight and Play automatically.

Store submission handled

We write the listing, produce screenshots and manage review — including the rejections.

Accessibility support

VoiceOver and TalkBack, dynamic type, and sufficient contrast throughout.

Stack

What we typically build this with.

A default, not a rule. If your team already runs something else and it fits the requirement, we work in your stack.

React Native

Both app stores from one codebase, with native modules where the platform genuinely differs.

Flutter

When the interface is highly custom and must be pixel-identical across platforms.

TypeScript

Types across the whole stack. Most integration bugs stop being possible.

Node.js

One language across client and server. Shared validation, shared types, one hiring profile.

PostgreSQL

Our default. Transactional integrity, JSON, full-text search and row-level security in one engine.

Firebase

Push, auth and realtime sync when speed to market beats control.

Redis

Caching, rate limiting, queues and sessions. Boring in the best way.

gRPC

Typed, binary service-to-service calls. Far cheaper than JSON over HTTP once services are chatty.

Why Devsock

The difference is in how the work is run.

Ten dimensions where engagements usually go wrong, and what we do instead. Every claim in the right-hand column is something you can verify in the first two weeks.

DimensionTypical agencyDevsock

Estimates
TypicalAn hourly rate and a range that grows once work starts.
DevsockFixed scope and fixed price after a paid discovery. Changes are quoted before they enter a sprint.
Communication
TypicalA weekly status email written by an account manager.
DevsockDirect access to the engineers building it, a shared board you can read any time, and a demo every second week.
Code ownership
TypicalDelivered at the end, sometimes with a proprietary framework attached.
DevsockYour repository, your cloud account, from commit one. No proprietary layer, no licensing.
Testing
TypicalManual clicking before launch, if the timeline allows.
DevsockAutomated suites in CI, load testing at projected peak, and a WCAG 2.2 AA audit before release.
Architecture
TypicalWhatever the available developer knows best.
DevsockA written architecture decision record explaining what we chose, what we rejected, and why.
Security
TypicalAddressed if the client raises it.
DevsockDependency scanning in CI, least-privilege access, secrets management and a pre-launch review as standard.
Accessibility
TypicalOut of scope unless legally forced.
DevsockWCAG 2.2 AA designed in and audited. Keyboard and screen-reader tested, not assumed.
Handover
TypicalA zip file and a phone number that stops answering.
DevsockDocumented architecture, runbooks, and a paid handover period so your team can genuinely take over.
After launch
TypicalA new quote for every bug.
DevsockDefect fixes covered for 90 days. Support retainers carry response-time SLAs in the contract.
Saying no
TypicalEvery request becomes a line item.
DevsockWe'll tell you when a feature isn't worth building, or when the answer isn't software at all.

Multi-tenant SaaS platform and driver apps for dumpster rental operators

Challenge

Dumpster rental operators run bookings, fleet position, driver assignments and invoicing across spreadsheets, whiteboards and phone calls. Nobody knows where a container actually is, proof of service arrives days after the job, and billing gets reconstructed from memory at month end.

Solution

A multi-tenant SaaS platform with self-serve signup, subscription billing and tiered plans, paired with native driver apps on iOS and Android. Operators get real-time container status, driver scheduling with route optimisation, customer and contract management, and automated invoicing. Drivers receive job assignments and upload proof of service from the field.

What shipped

Native driver apps published to both the App Store and Google Play
Multi-tenant architecture with per-operator data isolation
Self-serve onboarding with a 15-day trial and three subscription tiers
Real-time inventory and container status tracking
Driver scheduling with route optimisation
Automated invoicing and payment processing

Corporate platform for an independent renewable-energy consultancy

Challenge

An independent monitoring and evaluation consultancy for renewable energy projects needed to establish credibility with government, industrial and hospital buyers — a sector where procurement turns on verifiable regulatory standing and a demonstrable track record, not on marketing copy.

Solution

A structured corporate platform built around proof rather than persuasion: service definitions for independent oversight and technical training, a credentials section surfacing regulatory compliance across SECP, FBR, PRA and PEC, team profiles establishing sector experience, and a documented track record of verified installations. Enquiries route directly to the consultancy team.

What shipped

Structured service architecture across oversight and training lines
Regulatory credentials surfaced as the primary trust signal
Track record documented across government, industrial and public-health installations
Team credibility profiles with sector experience
Enquiry capture routed to the consultancy team
Server-rendered and fully indexable

Training platform with multi-country scheduling and certificate verification

Challenge

A QHSE training provider delivering internationally accredited certifications across Saudi Arabia, the UAE and Pakistan needed to publish a constantly moving multi-city schedule, take registrations online, and let employers independently verify that a certificate is genuine — the last of which is what makes an accreditation worth anything.

Solution

A training platform combining a published course schedule across multiple countries with online registration, a separate corporate training enquiry path, and a public certificate verification tool employers can use to authenticate credentials. Accreditation bodies and trainer profiles are presented as structured, checkable content rather than a logo wall.

What shipped

Public certificate verification for employers
Multi-country training schedule with online registration
Separate paths for open-enrolment and corporate training
Course catalogue spanning ISO, OSHA, IOSH, NVQ and Lean Six Sigma
Accreditation bodies and trainer credentials as structured content
Server-rendered and fully indexable
