## What is CTBrowser?

CTBrowser — CDISC Terminology, Anywhere

CTBrowser is a simple, fast, offline-first way to browse and search CDISC controlled terminology right on your iPhone. Once a terminology is downloaded, it stays on your device — no internet connection needed to look things up.

BROWSE
Select any downloaded terminology and browse its codelists. Tap a codelist to see its code, name, submission value, and whether it's extensible, followed by every term inside it — complete with submission value, code, definition, and synonym.

SEARCH
Full-text search across every terminology you've downloaded. Search by code, name, submission value, synonym, or definition, with matches highlighted right in the results. Found what you need? Jump straight to that term in its codelist with a single tap.

DOWNLOAD & MANAGE
Fetch the latest CDISC terminology list and download exactly the standards and versions you need over Wi-Fi. Remove anything you no longer need, or clear everything at once from the Files tab.

SUPPORTED STANDARDS
CDASH, SDTM, ADaM, SEND, Define-XML, Protocol, Glossary, DDF, TMF, and MRCT.

PRIVACY
CTBrowser does not collect, transmit, or track any of your data. All terminology data is stored only on your device.

Whether you're a clinical data manager, biostatistician, programmer, or researcher working with CDISC standards, CTBrowser keeps the terminology you need just a tap away.
