Complete guide
Everything you need to know
Software and app localization in Newcastle upon Tyne turns Tyneside SaaS platforms, mobile apps and Newcastle University spin-out products into globally shippable software across 150+ languages, priced from £30 per page under ISO 17100 controls. This service sits inside our wider Translation Services in Newcastle upon Tyne catalogue and wires directly into GitHub, GitLab and Crowdin CI/CD pipelines.
What types of software and apps can be localised in Newcastle upon Tyne?
Nine categories of software and apps are localised in Newcastle upon Tyne: SaaS platforms, iOS apps, Android apps, web applications, desktop software, embedded firmware UIs, e-commerce checkouts, ERP/CRM interfaces, and video games with XR applications. Each category has its own file formats, build toolchain and delivery target, and our team covers all of them under a single ISO 17100 certified workflow.
| Type of software | Typical file formats | Delivery target |
|---|---|---|
| SaaS platform | .json, .po, .resx, .yaml | Tenant-aware locale switching via API |
| iOS mobile application | .strings, .stringsdict, .xliff | Xcode + App Store Connect |
| Android mobile app | strings.xml, .arb | Gradle + Google Play Console |
| Web applications (React, Vue, Next.js, PHP) | i18next JSON, gettext .po, ICU | Sprint-aligned git branches |
| Desktop software | .resx, .properties, .qm | Windows, macOS, Linux installers |
| Embedded firmware UI | Custom string tables | Device flash image |
| E-commerce checkout | Platform resource bundles | Locale-scoped storefronts |
| ERP/CRM interface | XLIFF, database resource tables | Role-scoped UI rendering |
| Video games and XR | .csv, .xliff, engine-specific | Unity, Unreal, WebXR builds |
All nine categories are served across 150+ languages, with file format handling that spans .strings, .xliff, .xml, .json and .arb for mobile platforms, and broader interchange formats for web, desktop and embedded targets. Newcastle upon Tyne businesses — from early-stage startups at Newcastle University Ignite and PROTO through to established SaaS companies at Newcastle Helix — can localise any of these product types within a continuous delivery pipeline.
How are SaaS platforms localised?
SaaS platforms are localised by extracting resource files (.json, .po, .resx), running them through translation memory pretranslation, translating with domain-specialist linguists and re-injecting via API — with tenant-aware locale switching preserved throughout. Because SaaS products ship on continuous release cycles, the localization workflow is wired into GitHub, GitLab or Bitbucket so that every new key added to a feature branch is automatically queued for translation and returned before the sprint closes.
How are iOS and Android mobile applications localised?
iOS apps are localised through .strings, .stringsdict and .xliff files inside Xcode, while Android apps use strings.xml and .arb resources in Gradle. Both flows include App Store Connect and Google Play Console metadata, localised screenshots, keyword-optimised descriptions and push notification templates — meaning every touchpoint a user sees in the app store or inside the app is fully adapted for the target locale, not just the UI strings.
How are web applications and PHP/React front-ends localised?
Web applications built in PHP, React, Vue or Next.js are localised via i18next, gettext .po files or ICU MessageFormat, with translation memory tied to git branches for sprint-aligned delivery. Web and mobile front-ends share the same translation memory and termbase to keep terminology consistent across platforms — so a feature name introduced in the iOS app carries the same approved translation in the React web dashboard.
How is custom software built by a Newcastle software development agency localised?
Custom software built by a Newcastle software development agency is localised by embedding a localization specialist in the agile development team from the prototype stage, so string externalisation, locale switching and pseudolocalization run alongside the software delivery pipeline. Engaging localization at the prototype stage is significantly more cost-effective than retrofitting i18n to a mature codebase, because hard-coded strings, locale-unaware date logic and single-byte character assumptions are caught before they become architectural debt.
What content is included in software and app localization services?
Software and app localization services include 10 content types: UI strings, in-app help, error messages, push notifications, onboarding flows, App Store and Play Store listings, screenshots, marketing microcopy, legal notices, and release notes. Every content type requires a different localization approach — UI microcopy demands brevity and cultural resonance, legal strings demand precision and jurisdiction awareness, and App Store descriptions demand keyword optimisation for each regional store.
All 10 content types are handled within a single ISO 17100 certified workflow, with qualified native-speaker linguists assigned by domain and content risk level. Safety-critical error messages and legal notices are always translated and independently revised by human linguists; high-volume, lower-risk content such as release notes may use AI-assisted machine translation post-editing where the client approves that approach.
- UI strings across screens, menus, dialog boxes and status messages — the highest-visibility content in any app.
- In-app help and contextual tooltips — localised to match the terminology and UI labels of each target locale.
- Error messages and safety-critical warnings — always human-translated and independently revised; no AI-only processing.
- Push notifications and transactional templates — adapted for cultural tone and character limits on each platform.
- Onboarding flows and first-run tutorials — structured to guide new users from a standing start in their native language.
- App Store and Play Store titles, descriptions, keywords and promotional text — optimised for regional store search algorithms.
- Localised screenshots and preview videos — reflecting the localised UI so store listings are fully consistent.
- Marketing microcopy and CTAs — culturally adapted, not literally translated, to drive action in each market.
- Legal notices, terms of service and UK GDPR privacy strings — jurisdiction-aware and reviewed for regulatory compliance.
- Release notes for every version bump — keeping users informed in their own language at every update.
Why us
What are the benefits of localising software and apps for Newcastle upon Tyne businesses?
How does localisation improve user experience and app-store conversion?
Localisation improves user experience by presenting UI in the user’s first language, adapting date and currency formats, and localising app-store screenshots and keyword fields, which raises App Store and Play Store conversion meaningfully in each regional store. When onboarding flows, error messages and push notifications all read as native rather than translated, users complete activation steps at higher rates and generate fewer support tickets — directly reducing operational cost for the Newcastle business behind the product.
How does localisation support entry into new target markets from the North East?
Localisation supports target market entry from the North East by adapting digital products to the linguistic, regulatory and cultural expectations of each locale, so a Newcastle SaaS company can sell into Germany, France, Spain and the Gulf without rebuilding software. Because the ISO 17100 workflow covers UI strings, in-app help, legal notices and store listings in a single pipeline, a Tyneside product team can green-light a new language market and receive localised builds within a single sprint cycle. Same-day turnaround is available for urgent market launches of up to 10,000 words, at a defined surcharge, meaning commercial deadlines do not have to wait on localization.
How does localisation reduce support costs?
A fully localised product is a self-explanatory product in every market it serves. When error messages are accurate and culturally appropriate, when onboarding flows guide users in their native language, and when in-app help answers questions in the right locale, the volume of support tickets routed to the Newcastle product team falls. Businesses that localise comprehensively — covering error messages, push notifications and help content, not just UI labels — consistently report lower per-user support costs in new language markets than in markets served only in English.
Is AI used in software and app localization, or is human expertise still required?
AI is used in software and app localization for pretranslation, terminology suggestion and machine translation post-editing (MTPE), but ISO 17100 still requires a qualified human linguist to translate or post-edit every segment, and a second qualified linguist to independently revise the output. AI cannot reliably judge UI context, cultural nuance, brand tone or the legal precision demanded by privacy strings and terms of service — making human expertise non-negotiable for the content types that define a product’s quality in a new market.
Translation memory pretranslation is distinct from AI generation: it replays segments that a human linguist already approved in a prior release, which is why it delivers 30–70% cost savings on iterative builds without any reduction in quality. AI machine translation engines are used selectively, on content types where the risk of a mistranslation is low and the volume is high.
| Content type | AI-first (MTPE) | Human-first |
|---|---|---|
| Internal help articles | Yes | Optional review |
| Repetitive release notes | Yes | Light post-edit |
| UI microcopy and buttons | No | Yes |
| Error messages (safety-critical) | No | Yes |
| App Store descriptions | No | Yes |
| Legal and privacy strings | No | Yes |
Where does machine translation with AI post-editing (MTPE) fit?
Machine translation with AI post-editing fits high-volume, low-risk content such as internal help articles and repetitive release notes, where an AI engine produces a draft and a human linguist edits it to an ISO 17100 standard — cutting cost 30–50% while preserving the mandatory revision step. The decision to use MTPE is always made per content type and per language pair, based on engine performance data for that combination, never applied globally across a project.
Where do human linguists remain essential?
Human linguists remain essential for UI microcopy, safety-critical error messages, App Store descriptions, legal terms, push notification copy and any string where cultural nuance or brand voice determines product perception. AI translation engines misread polysemy — words that mean different things in different UI contexts — and consistently underperform on RTL typography, gender agreement in inflected languages, and the kind of compressed, action-oriented copy that drives conversions in app store listings. For these content types, human-first translation under ISO 17100 is the only workflow we offer.
Pricing
How much does software and app localization cost in Newcastle upon Tyne?
Software and app localization in Newcastle upon Tyne starts from £30 per page (approximately 250 words), with ISO 17100 human translation and independent bilingual revision included at the base rate. Translation memory discounts reduce the cost of iterative releases by 30–70%, and same-day rush turnaround carries a surcharge of 25–50% on jobs up to 10,000 words. Because pricing is calculated on extracted word count rather than file count, Newcastle development teams pay only for the translatable content — not for code, markup or comments in the resource files.
| Line item | Rate (GBP) | Notes |
|---|---|---|
| Base translation rate | from £30 per page (~250 words) | Includes ISO 17100 revision |
| 100% TM match | 10–25% of base | Reused verbatim from prior release |
| Fuzzy match (75–99%) | 50–75% of base | Discount by match band |
| Repetitions | 25% of base | Same segment repeated in file |
| New words | 100% of base | Full linguist rate |
| Volume discount (10,000+ words) | 5–15% off | Tiered by monthly commit |
| Same-day rush surcharge | +25–50% | Up to 10,000 words |
What is included in the £30 per page rate?
The £30 per page rate covers ISO 17100 translation by a native-speaker linguist with software domain experience, independent bilingual revision by a second qualified linguist, translation memory setup and population, terminology management via a client-specific termbase, and delivery in the original file format — whether that is .strings, .xliff, strings.xml, .json, .arb or any other standard resource format. There are no additional charges for file handling, project management or translation memory maintenance on ongoing accounts.
How do volume discounts and translation memory affect quotes?
Volume discounts stack with translation memory leverage to produce compounding savings across iterative releases. 100% TM matches are billed at 10–25% of the base rate, fuzzy matches at 50–75%, and repetitions at 25%, so a Newcastle app that ships fortnightly sprints with incremental string changes will see its per-sprint localization cost fall progressively as the translation memory matures. Across a full product release cycle, these savings typically reach 30–70% compared with the cost of translating the same word count fresh each time.
How do I pay for translation services?
Translation services are paid in GBP by bank transfer, credit card or purchase order, with net-30 terms available for B2B accounts and 50% deposits standard on projects above £5,000. Newcastle Helix and PROTO-based businesses with ongoing localization programmes can arrange monthly invoicing against a committed volume to simplify budget management.
How long does software and app localization take in Newcastle upon Tyne?
Software and app localization in Newcastle upon Tyne runs at the ISO 17100 throughput benchmark of 1,500–2,000 words per linguist per day, which is the industry-standard quality pace for human translation with independent revision. A 5,000-word app update takes 3–5 working days per language at standard turnaround, and same-day turnaround is available for rush jobs up to 10,000 words at a 25–50% surcharge — making it possible to localise a hotfix or urgent store listing update within a single business day.
Turnaround times scale predictably with word count, and parallelisation across multiple linguists compresses delivery for larger projects. Translation memory shortens effective turnaround on iterative releases because previously approved segments are pretranslated instantly, meaning only net-new strings enter the human translation queue.
| Project size | Per language turnaround | Sprint fit |
|---|---|---|
| Up to 2,000 words | 1 working day (same-day on rush) | Mid-sprint hotfix |
| 2,000–5,000 words | 3–5 working days | One-sprint release |
| 5,000–15,000 words | 1–2 weeks | Two-sprint release |
| 15,000–40,000 words | 3–4 weeks | Quarterly release |
How is turnaround compressed for agile sprint releases?
Turnaround is compressed for agile development by parallelising linguists across target languages, using translation memory to skip previously translated strings, and streaming new strings into the CI/CD pipeline via GitHub, GitLab or Crowdin webhooks the moment they merge to the main branch. Because the continuous localization integration queues new strings automatically, there is no manual handoff delay between the engineering team committing a string and a qualified linguist beginning work on it. For Newcastle product teams running two-week sprints, this means localised builds can be ready for QA at the same time as the English release candidate — not days or weeks later.

Why does ISO 17100 certification matter for software localisation?
ISO 17100 certification matters because it mandates qualified linguist competence, independent bilingual revision, terminology management and project management controls — the same controls that stop a rogue string breaking a production app-store submission.
How is information security and ISO 27001 handled?
Information security follows ISO 27001 aligned controls: signed NDAs with every linguist, encrypted SFTP or CAT-tool cloud transfer, UK GDPR-compliant UK data processing, and role-based access to source code and string files. Quality and security are audited on every project.
Do you use translation memory and glossaries?
Yes — every Newcastle software project runs on a dedicated translation memory and termbase managed in Trados, memoQ or Crowdin, so brand vocabulary, product names and UI conventions stay consistent across every release and every linguist. Translation management is owned by a named project manager.
