Professional software translation services for apps and UI

Growing internationally means speaking to users in their language while preserving the exact intent and behaviour of your software. Our team blends linguists with domain expertise—SaaS, fintech, gaming, medtech, cybersecurity, and more—with localisation engineers who understand formats, placeholders, and constraints. The result: UI strings that read naturally and function flawlessly.

With the KoT Intuit AI+Human platform, you get up to 50% lower costs and enterprise‑grade accuracy (up to 99.9%) through terminology control, translation memories, and context‑rich workflows. We translate UI strings, notifications, release notes, tooltips, and help content in 120+ languages, ensuring consistent voice across platforms and versions.

We preserve identical layout and design fidelity. From right‑to‑left languages to character expansion, our team adapts spacing and truncation rules without breaking your UI. DTP specialists and localisation engineers work together to protect visual hierarchy in screenshots, onboarding flows, and embedded graphics.

Beyond translation, we help you optimise App Store and Google Play listings for search and conversion in each locale. Clear, culturally relevant copy boosts click‑through and retention, improving ROI for paid and organic acquisition campaigns.

As a global agency known for exceptional customer care, Kings of Translation provides dedicated project managers who learn your product and roadmap. Our 98% client return rate reflects consistent delivery, proactive communication, and measurable business impact across releases.

Engineered for product teams, our process integrates seamlessly with your toolchain. We support JSON, iOS .strings, Android XML, XLIFF, YAML, RESX, PO, CSV, HTML, Markdown, and more. We work from Figma screenshots or context files to capture meaning, reduce ambiguity, and prevent truncation or placeholder errors.

Each project begins with a terminology brief and style guide, followed by translation using translation memories and glossaries to ensure consistency across modules and versions. Linguistic QA and functional checks verify placeholders, variables, and UI behaviours. For critical flows, we provide in‑context LQA and screenshot validation.

Layout integrity matters. Our DTP specialists preserve identical layout in help centres, knowledge bases, PDFs, and in‑app visuals. We manage RTL languages, font fallback, and line breaks so your UI remains clean and accessible. Expect clean delivery with versioning notes and change logs.

Speed without compromise: small updates often return within 24–48 hours; larger releases follow sprint‑based plans with daily handoffs. Standard translation is from £0.05 per word; expedited options are available. Transparent estimates, no surprises, and reliable deadlines keep your engineering and marketing timelines intact.

Security and governance are built in. We support NDAs, encrypted file handling, and minimal‑access workflows. Our credentials include BBB A+ rating and ATA membership, and our certified translations are accepted worldwide by institutions, including USCIS and British authorities when certification is required for accompanying documents.

As a UK‑focused, globally operating team, we align with British English standards, privacy expectations, and accessibility guidance while delivering content accepted across international markets. Whether your users are in London, Singapore, or São Paulo, translations are prepared for worldwide use in business, academic, and technical contexts.

Budget predictability matters. Our standard software translation pricing is from £0.05 per word, with transparent quotes and scalable volume discounts. If you also need certified translations for related documents—such as compliance statements, contracts, or tender submissions—we provide them from £29.90 per page and ensure they are recognised internationally.

Continuous localisation support keeps you release‑ready. We maintain translation memories and termbases, so each sprint gets faster and more consistent. When you push updates, we translate only the delta, lowering cost and risk while protecting brand voice and UX patterns across every locale.

For complex projects, we partner with your developers and product owners to design a localisation strategy: source string optimisation, variable handling, pluralisation rules, and internationalisation checks. This prevents rework and accelerates time‑to‑market, helping you enter new regions with confidence.
