Who You Work with on Your App

Tyneside has a lively digital and data scene, and we work with its founders, CTOs and product managers. Expect a named lead and straightforward contact from the first conversation.

A Named Lead, a Wide Bench

Delivery sits with one project lead, who picks up when you call. A bench of iOS, Android and cross-platform engineers, designers and QA stands behind them, ready to back a data-minded team on Tyneside.

Clear Contact Between Meetings

We meet on video or in person by arrangement, then follow with short written updates. They set out what was decided, what moved and which questions need an answer from you.

Joined Up with Your Team

We join forces with your product owner, IT staff, in-house developers and any supplier already on board. With clear documentation and a tidy handover, your own people can take care of the app afterwards.

Apps We Build for Newcastle Upon Tyne Sectors

iOS, Android or Both? A Plain-English Guide

Users, budget and features decide which route suits you. Here are the four routes, compared head to head.

Option

Native iOS

iOS app development

Pick it when

The bulk of your audience owns iPhones, or Apple’s own features matter a lot.

Watch for

Android users need a second build.

Option

Native Android

Android app development

Pick it when

Most of your audience uses Android, or you need strong device access.

Watch for

iPhone users need a second build.

Option

Cross-Platform

Flutter and React Native

Pick it when

A single codebase gives you both platforms and a lean budget.

Watch for

Certain hardware features could need native code.

Option

Web App or PWA

Web application development

Pick it when

People will not install anything, or you’re still sounding out demand.

Watch for

Narrower device access, and no store listing at all.

Torn between them? Many teams go cross-platform first and add native code for the one feature that requires it.

What We Check Before an App Goes to the Stores

Plenty of first releases get held up in store review. We follow this list each time.

Read the Current Guidelines

Apple's App Review Guidelines →

Each feature checked against Apple’s App Review Guidelines and Google Play policies

Privacy information and permission prompts worded in everyday terms

Crashes and slowdowns hunted down on a range of real devices

Sign-in, payments and account deletion run through end to end

Accessibility tested, covering text size and screen reader support

Analytics and crash reporting working before the launch date

Store listing copy, screenshots and rating prompts ready to go

Release and update planning, with someone assigned to watch reviews

What Shapes the Cost of an App

Prices stay off this page, because one app can be a simple booking tool and another a data platform. Quotes in writing let you weigh us against other suppliers. Six factors drive the effort.

Platforms

↑ Costs more when

you want separate native apps for each phone platform

↓ Costs less when

one shared build serves iOS and Android

Features

↑ Costs more when

maps, payments, chat and offline mode are all needed

↓ Costs less when

launch day depends on a single core journey

Design

↑ Costs more when

the brief calls for custom animation and a full design system

↓ Costs less when

standard interface patterns match your brand

Integrations

↑ Costs more when

it must read from sensors, data platforms or legacy systems

↓ Costs less when

it talks only to documented, standard APIs

Back End

↑ Costs more when

live data, admin tools and analytics have to be created

↓ Costs less when

you can reuse a back end that already works

Compliance

↑ Costs more when

health, financial or other sensitive records are involved

↓ Costs less when

the information it holds is low-risk

Hire Mobile App Developers

Match the engagement to your stage. A startup’s first release suits a fixed build, while a Tyneside product team adding capacity suits dedicated developers.

Fixed Price Build

Scope, milestones and price fixed before work begins. A good fit for firm requirements and a set launch date.

Suits

Time and Material

You pay for time spent and reshuffle priorities every sprint.

Suits

Products shaped by what users tell you

Dedicated Developers

Mobile developers, QA and a designer when needed, inside your sprints and tools.

Suits

A long roadmap

How to Choose an App Development Company

Proposals look alike on paper. These seven questions show how a team behaves between kick-off and launch.

Which Engineers Will Build My App?

Listen for

People and roles named, not a broad promise.

When Do I See Something Working?

Listen for

A build you can install when every sprint finishes.

Who Will Hold the Code and the Store Accounts?

Listen for

You do, and it’s written in the contract.

What If the Previous Supplier Never Finished the App?

Listen for

A code and architecture review first, then a written plan with options.

Who Looks After the App After Launch?

Listen for

Support, monitoring and updates agreed before go-live.

How Do You Work with Our Product Owner and Developers?

Listen for

Shared boards, daily stand-ups and code reviews.

Would You Advise Against an App?

Listen for

Yes. If a web app or an existing tool fits better, we say so.

How We Run an App Project

Six stages, each finishing with something you can inspect. Timings flex with the size of the app.

Discovery

About a week of workshops on users, data sources and constraints.

Scoping and UX

Typically one to two weeks to agree a scope, user flows and a written quote.

Design and Prototype

Around two weeks for a prototype you can click through with test users.

Sprint Builds

Short sprints, each closing with a build ready to install.

Testing and Store Readiness

A testing phase of around four weeks across devices, performance and store rules.

Launch and Iterate

We release, monitor and plan version two.

Each stage ends with something you can review.

Frequently Asked Questions

What Does an App Development Agency in Newcastle Upon Tyne Do?

Such an app development company handles planning, design, building, testing and support for mobile apps. It hooks the app up to your data and other systems, takes care of App Store and Google Play submission and maintains the app after release, so a single team is answerable from workshop to live version.

Does Syndell Offer App Development in Newcastle Upon Tyne?

Yes. We build apps for Newcastle upon Tyne businesses and meet on video or in person by arrangement. Tell us about the idea or the app you already run, and we’ll suggest whether a workshop, a prototype or a full build makes the sensible start.

How Much Does App Development Cost?

Figures come after a conversation, since two apps that look alike can differ greatly in effort. Following a free consultation you receive a written quote, priced as a fixed build, time and material or a dedicated team, with a sprint plan attached.

Should I Build for iOS, Android or Both?

All three are possible. Native iOS apps are written in Swift, native Android apps in Kotlin, and cross-platform apps in Flutter or React Native. During discovery we weigh them against your audience, budget and features, then recommend one and explain the trade-offs in plain terms.

Our App Stalled with Another Supplier. Can You Help?

Yes. A code and architecture review comes first, then we say whether to fix, refactor or rebuild. A written summary sets out what we found and what to fix first, so a CTO or product manager can decide before putting in more budget.

I Am a Founder with an Idea. Can You Build an MVP?

Yes. We help founders agree the smallest release that tests the idea, then build it in short sprints with clear user experience and a plan for later versions. A focused MVP is usually a matter of months, and we say early if the date needs less scope.

Can I Hire App Developers for One Part of the Work?

Yes. You can hire mobile developers for a single feature, to rescue a stalled app or for a long roadmap. Choose fixed price, time and material or a dedicated team, with support after release, depending on how settled your plans are.

Do You Have App Developers for Gateshead and North Tyneside?

Yes. Our clients are spread across Tyneside, among them Gateshead, Tynemouth, Whitley Bay and South Shields, and we meet on video or in person by arrangement. Bring rough sketches or your existing app. We will advise on what to build first and what can follow.
