4DI 1.6 • Made for iPhone Duo: half open, one half holds the definition or finding you picked, the other lets you browse and compare. • Fully open, the list and its details sit side by side like a book. Your selection and scroll position stay when you fold or unfold. Your bookmarks and settings stay as they are.

4DI 1.5 • 4DI now also speaks Spanish and Italian, in addition to English, German and French. • A new installation starts in your iPhone's language when 4DI supports it. You can switch the language any time in the app's Settings. Your bookmarks and settings stay as they are.

4DI 1.4 • ALCOA++ updated: the tenth principle is now "Traceable" (English, German, French), following the EMA guideline on computerised systems and electronic data in clinical trials (2023) and the draft revision of EU GMP Chapter 4 (2025) — with a new definition, practical examples, and links in the data lifecycle and inspection findings. It replaces "Trustworthy", which is not an attribute in any official source. • New framework: the EMA guideline on computerised systems (2023), including comparison entries. • WHO references updated to the current WHO data integrity guideline TRS 1033 Annex 4 (2021), which replaces TRS 996 Annex 5. • Glossary complete in all three languages with correct German and French spelling; search now also finds terms typed without accents. • Principle colours and icons now display correctly in German and French lifecycle and findings views. • A short "What's New" screen appears once after each update. • Built for iOS 27; new "Community & Feedback" section in Settings. Your bookmarks, language and appearance settings carry over unchanged.

Added the "Trustworthy" principle to the ALCOA++ tab, completing the full set of 10 ALCOA++ principles. Includes detailed definition, 3 practical examples with correct practices and common violations, covering system validation, quality culture, and personnel qualification. Fully available in English, German, and French.

NEW: Data Lifecycle Explorer Follow data's complete journey through a GxP environment -- from creation to destruction. An interactive visual timeline guides you through all six lifecycle stages: Creation, Processing, Review and Approval, Reporting, Retention, and Archival/Destruction. Each stage shows which ALCOA++ principles matter most at that phase, common pitfalls to avoid, relevant regulatory references, and actionable best practices. Fully trilingual (EN/DE/FR). NEW: Common Findings Explorer A categorized, searchable collection of 17 typical data integrity inspection findings -- the kind of things FDA Warning Letters and EU GMP non-compliances flag. Each finding includes a detailed description of what went wrong, which ALCOA++ principles were violated and why, the regulatory basis citing specific frameworks, and step-by-step recommended remediation. Findings are organized into five categories: Electronic Systems, Laboratory Practices, Manufacturing Documentation, Quality Oversight, and Data Storage. Includes links to official regulatory databases (FDA Warning Letters, EMA GMP reports, MHRA Inspectorate, PIC/S, WHO). Fully trilingual (EN/DE/FR). REMOVED: GEMBA Walk The GEMBA Walk documentation tool has been removed in this version. Camera and photo library permissions are no longer required. The app now features five tabs: ALCOA++ Principles, Regulatory Frameworks, Data Lifecycle Explorer, Glossary, and Common Findings.
