What is software and app localization?
Software and app localization is the process of translating and culturally adapting a software product — UI strings, error messages, store listings, help content and embedded assets — into a target locale so users read, click and pay in their own language, currency, date format and cultural conventions.
What software and app localization services are offered in Bristol?
Software and app localization services in Bristol cover mobile app localization (iOS and Android), SaaS and web application UI translation, store listing and ASO localization, help-centre and knowledge-base localization, media translation for in-app video and captions, and continuous localization wired into the client’s CI/CD pipeline.
What is the software and app localization process step by step?
The software and app localization process runs in 7 steps: scope and file audit, internationalization check, pseudolocalization QA, translation by native subject-matter linguists, in-context review with screenshots, locale-aware QA (dates, plurals, GBP and target currencies), and CI/CD reintegration through XLIFF or Git.
How much does software and app localization cost in Bristol?
Software and app localization in Bristol is priced from £30 per page (250 source words) or approximately £0.12 per word, with volume discounts above 10,000 words, a 25–50% surcharge for same-day rush, and separate flat fees for pseudolocalization QA, in-context screenshot review and ongoing continuous localization retainers.
How long does software and app localization take in Bristol?
Software and app localization in Bristol runs at the ISO 17100 throughput of 1,500–2,000 words per linguist per day: a 500-word onboarding flow returns same-day, a 5,000-word mobile app ships in 3 working days, and a 50,000-word SaaS platform localizes into 5 languages in 4–6 weeks with parallel linguist teams.
What factors should you consider when choosing a software or app localization company in Bristol?
Choose a Bristol software localization partner on 8 factors: ISO 17100 certification, native subject-matter translators, engineering literacy with XLIFF and Git, CAT tool and translation memory ownership, pseudolocalization and in-context QA, locale coverage across your target markets, GBP-transparent pricing, and same-day rush capability.

What we offer
What software and app localization services are offered in Bristol?
Software and app localization services in Bristol cover six delivery lines: mobile app localization for iOS and Android, SaaS and web application UI translation, store listing and ASO localization, help-centre and knowledge-base localization, media translation for in-app video, and continuous localization wired into the client’s CI/CD pipeline. The service is based in Bristol and serves the South West.
- Mobile app localization (iOS, Android, Flutter, React Native)
- SaaS and web applications localization
- App Store and Google Play listing localization (ASO)
- Help centre and knowledge base localization
- Media translation: subtitles, dubbing, on-screen text
- Continuous localization retainer with a named account lead
How is mobile app localization delivered for iOS and Android?
Mobile app localization is delivered against .strings (iOS), .xml (Android), .arb (Flutter) and .json (React Native) files. In-context screenshot QA runs per locale before App Store and Google Play submission. Apple’s App Store Connect now supports metadata in 50 locales; Google Play matches store listings to a user’s language preference.
How is SaaS and web application localization handled?
SaaS and web application localization is handled through XLIFF, .po and JSON exports connected via Git or API. Translation memory reuse across releases keeps recurring UI strings consistent every sprint. Our CAT tool stack covers memoQ, Trados and Phrase.
How are store listings and ASO localized?
Store listings are localized with keyword localization rather than literal translation. Native-language app store search terms are researched per locale. The title, subtitle, description and screenshot captions are then rewritten by native translators to match discovery intent in each market.
Which media translation and in-app content types are covered?
Covered media translation formats include in-app video subtitles, dubbed voice-over, on-screen text overlays, tutorial captions and marketing trailers. Deliverables ship as SRT, VTT or burned-in graphics, matched to the product’s UI language.
Are certified translation and interpreting services available alongside?
Certified translation and interpreting services in Bristol are available alongside software localization for regulated content. Terms of service, privacy notices, medical device UI and financial disclosures are handled by the same ISO 17100 team. Terminology stays consistent across the product and its legal wrapper. British Sign Language interpreting is available on request.
How it works
What is the software localization process step by step?
1
How are source files and non-translatable elements identified?
Source files are audited to extract translatable strings from .po, .xliff, .strings, .xml, .arb, JSON and IDML. Non-translatable elements — HTML tags, ICU placeholders, variables, tokens, tracking parameters and brand names — are locked with a termbase and protected in the CAT tool before any translator touches them.
2
What is pseudolocalization and why run it first?
Pseudolocalization replaces every source string with accented, expanded variants such as “Ĥéļļõ Ŵöŗļđ”. Developers surface truncated UI, hardcoded strings and RTL bugs before a single word is paid for in translation. It runs as a QA gate before translation memory commit.
3
How does in-context review with screenshots work?
In-context review pairs each translated string with a live screenshot from the iOS or Android build. The reviewer sees the string inside its actual button, tooltip or dialog. This catches over-run text, wrong tone or ambiguous UI copy before release — hardcoded GBP symbols, wrong date separators and missing plural forms are flagged here.
4
How are translated files returned safely to the platform?
Translated files return to the platform via the same XLIFF, JSON or Git branch they came from — never copy-pasted from spreadsheets. A checksum diff, placeholder integrity check and locale-aware QA report attach to the delivery. The build pipeline merges without regression.
Pricing
How much does software localization cost in Bristol?
Software and app localization in Bristol is priced from £30 per page (250 source words) or approximately £0.12 per word GBP, with volume discounts above 10,000 words and a 25–50% surcharge for same-day rush. Pseudolocalization QA, in-context screenshot review and continuous localization retainers carry separate flat fees.
| Item | Bristol rate (GBP) |
|---|---|
| Standard European locales | from £0.12 / word · £30 / page |
| Low-resource languages (Icelandic, Welsh, Māori) | from £0.18 / word |
| Rare Asian scripts | from £0.20 / word |
| Same-day rush surcharge | +25% to +50% |
| AI-assisted (MT + post-editing) | 30–50% below human-only |
| Volume discount (10,000+ words) | tiered, quoted per project |
What is the price per word, per page and per locale?
Baseline pricing starts at £30 per page or £0.12 per word for standard European locales. Rates rise for low-resource languages and rare Asian scripts. Rates drop with translation memory leverage as repeated UI strings recycle across releases.
What surcharges apply for same-day and rush turnaround?
Same-day and rush software localization carries a 25–50% surcharge on the £30-per-page baseline. It applies when the job exceeds the ISO 17100 throughput of 1,500–2,000 words per linguist per day. Additional linguists are then parallelised under one lead reviewer.
How does AI-assisted translation change the price?
AI-assisted, or MT with post-editing, reduces cost by roughly 30–50% on high-repetition UI microcopy and help content. Safety-critical strings, legal wrappers and store-listing ASO copy stay on the full human-translator rate to protect brand and compliance. Post-editing follows ISO 18587.
How long does software and app localization take in Bristol?
Software localization in Bristol runs at the ISO 17100 throughput of 1,500–2,000 words per linguist per day. A 500-word onboarding flow returns same-day. A 5,000-word mobile app ships in 3 working days. A 50,000-word SaaS platform localizes into 5 languages in 4–6 weeks with parallel linguist teams.
| Project size | Languages | Turnaround |
|---|---|---|
| 500-word onboarding flow | 1 | Same-day |
| 5,000-word mobile app | 1 | 3 working days |
| 20,000-word SaaS module | 3 | 10–14 working days |
| 50,000-word SaaS platform | 5 | 4–6 weeks |
What is the same-day turnaround limit?
Same-day turnaround handles up to 10,000 source words per language pair when briefed before 10:00 GMT. The 25–50% rush surcharge applies. Parallel linguists work under a single lead reviewer to preserve terminology consistency.
How does continuous localization compress the timeline?
Continuous localization wires XLIFF exports into the Git workflow. New UI strings translate inside the same sprint they were written — typically within 24–48 hours of merge — instead of waiting for a batched release patch. This is our continuous localization Bristol pattern for agile teams.
What factors should you consider when choosing a software localization company in Bristol?
Choose a Bristol software localization partner on 8 factors: ISO 17100 certification, native subject-matter translators, engineering literacy with XLIFF and Git, CAT tool and translation memory ownership, pseudolocalization and in-context QA, locale coverage across your target markets, GBP-transparent pricing, and same-day rush capability.
- ISO 17100 certification with traceable revision records
- Native subject-matter translators, not generalists
- Engineering literacy — XLIFF, Git, ICU plurals
- CAT tool ownership (memoQ, Trados, Phrase)
- Pseudolocalization and in-context QA in-house
- Locale coverage matching your export corridors
- GBP-transparent pricing, no hidden retainers
- Same-day rush capability with a named account lead
Why does ISO 17100 certification matter for software localization?
ISO 17100 certification enforces a documented translator plus independent reviewer workflow. Translator qualifications and revision records are traceable. Regulated Bristol fintech, medtech and aerospace clients need this audit trail when localized UI strings become part of the product record. It also aligns to ISO 17100.
What technical expertise should the localization partner have in-house?
Required in-house technical expertise includes CAT tool administration, file-format parsing, Git and API integration, ICU MessageFormat handling and pseudolocalization scripting. Most Bristol translation agencies do not staff these capabilities.
- CAT tool administration: memoQ, Trados Studio, Phrase
- File parsing: .po, .xliff, .strings, .arb, JSON
- Git and API connector setup
- ICU MessageFormat for pluralisation
- Pseudolocalization scripting for QA
How is data security handled for pre-release source files?
Pre-release source files are handled under NDA and stored inside UK/EU data centres. Access is limited to vetted in-house and freelance linguists on encrypted CAT platforms. Files purge from translator workstations at project close. This protects unreleased features and aligns to UK GDPR and the Data Protection Act 2018.
Do you offer ongoing support and continuous localization after launch?
Ongoing support runs as a continuous localization retainer. New UI strings, help content, landing pages and store-listing updates translate inside the client’s Git or Phrase workflow on a rolling weekly cadence. A named account lead and 24/7 technical support contact cover release windows.
Why us
What are the benefits of localizing software and apps for Bristol businesses?
Which export markets do Bristol product teams target most?
Bristol product teams most often target Arabic (MENA aerospace and fintech), Mandarin and German (tech and aerospace supply chains), French (regulated markets), Spanish and Portuguese (Iberia and LATAM), and Czech, Slovak and Ukrainian (CEE engineering hubs in Eastern Europe). Marketing sites feeding these apps sit under Website Localization in Bristol.
How does localization improve UX and customer experiences?
Localization improves UX and customer experiences by matching each string to native reading order, plural rules, date and currency formats, and cultural tone. A machine-translated app that feels foreign becomes a product users trust with payment credentials and personal data. Digital experiences localize into tailored solutions per market.
How it works
How does AI impact software localization workflows?
1
Where is AI-powered translation safe to use?
AI-powered translation is safe on repetitive UI microcopy, help-centre articles, changelog notes and internal tooling. Risk of a mis-translated string is low. Translation memory leverage is high. Digital transformation projects with predictable content benefit most.
2
Where does AI-powered translation fail?
AI-powered translation fails on legal wrappers, medical device labels, safety-critical error messages, brand voice marketing, App Store keyword localization and low-resource languages. Here a native subject-matter translator protects the client. Best practices reserve human-only workflows for regulated content under the EU MDR and the European Accessibility Act.
3
How is automation used to reduce turnaround time?
Automation reduces turnaround by automating file ingestion via Git and API connectors, auto-populating translation memory matches, triggering pseudolocalization on every pull request, and routing finished locales back into the build. Manual copy-paste disappears. Engineering overhead per release drops by hours. We automate the round-trip so releases stay on schedule.
Which companies in Bristol provide software localization services?
Bristol software and app localization is offered by a small set of specialist translation agencies — including this ISO 17100 certified service line — a handful of localization-aware software development companies, and directory-listed generalist providers. Most generalists sub-contract the linguistic work.
How do specialist translation agencies differ from Bristol software development companies?
Specialist translation agencies own the linguistic workflow — native translators, CAT tools, ISO 17100 review — while software development companies own the codebase. The former localize what the latter built. Mixing the two under one roof usually means one side is being sub-contracted. Bristol product teams commissioning custom software from an agency such as newicon or Ghyston still route the translation software work to a translation agency for ISO 17100 sign-off. Directory listings on Goodfirms often surface generalist providers, including operators such as soVision IT, Easy-Translations Ltd or ApLingo, whose scope varies.
