Our Process

  1. 1. Pipeline Integration

    Connect via webhook, API or CLI to your repo and/or TMS. We assign the right specialist linguists per content type and lock in glossary and tone up front.

  2. 2. Continuous Translation

    New strings detected on commit, processed through our LingoSecure pipeline, reviewed by native linguists in full context, returned as a PR or file drop inside a 24-hour SLA.

  3. 3. Pseudo-Locale & LQA

    Pseudo-locale build catches truncation and layout breaks before staging. Second-linguist review, screenshot-context QA, cultural sanity check.

  4. 4. Merge, Test & Ship

    Translations merge back to your repo, pass your CI, ship on your release cadence. Version-pinned TM so v4.2 never ships with v4.1 strings.

  5. 5. Continuous Updates

    Monthly retainer keeps every locale fresh as your product evolves. Help centre, push notifications, release notes, marketing all live through the same pipeline.

Frequently Asked Questions

Common questions about mobile app localisation

How is this different from Lokalise, Phrase or Crowdin?

They are TMS platforms - they hold your strings, they don't translate them. You still need a vendor. We are the vendor: our own secure portal, our own linguists, specialist linguist matching, integration into your existing TMS if you already have one. One UK contract, one invoice, one PM.

What file formats and frameworks do you support?

iOS: .strings, .stringsdict, .xliff. Android: strings.xml. Cross-platform: .arb (Flutter), .json, .resx, .properties, .yaml, ICU MessageFormat. Frameworks: native Swift/Kotlin, React Native, Flutter, Xamarin, Ionic, KMM. Version control: GitHub, GitLab, Bitbucket.

Do you handle App Store and Google Play listings?

Yes. App titles, subtitles, descriptions, keywords and screenshot copy - localised with local keyword research for each target market. Not literal translation. We target rankings in-market, not a word-accurate listing that nobody searches for.

Can you handle Arabic and RTL for mobile?

Yes - Arabic is our strongest specialism. Mirrored layouts, bidi text handling (English numbers in Arabic paragraphs), font rendering verified on target devices, dialect choice per market. We don't charge the 20-30% RTL surcharge most agencies add - this is the work we do most. Based outside the UK? Our Arabic localisation studio, Arabic Translation Service, works with companies worldwide.

How do you handle fintech and regulated copy?

KYC flows, legal disclosures, T&Cs, privacy policies, consent banners and disclosures - all adapted for GDPR (EU), CCPA (California), LGPD (Brazil), DSA (EU) and jurisdiction-specific rules. Flagged copy goes to a second-reviewer with regulatory expertise before release.

What does it cost?

We scope per project, not per word, for continuous localisation. A small mobile app in 5 languages with continuous updates starts in the low thousands per month; larger SaaS / fintech programmes in 10+ languages are scoped directly. Tell us what you're shipping and we'll return a scoped number in 24 hours.

Do you localise more than apps?

Yes. Apps are one part of our wider localisation services: software, websites, e-learning and multimedia handled by one team with a shared translation memory, so your app copy stays consistent with everything else you ship.
