How to pronounce iOS
product community-consensus
iOS is most commonly pronounced "eye oh ess" (/ˌaɪ oʊ ˈɛs/). This is the widely-used reading among engineers, though edge cases exist.
Three letters with the 'i' as in iPhone: 'eye-oh-ess', /aɪ oʊ ɛs/. Never 'eye-oss' and never 'ee-oss'.
Pronouncing project and product names correctly avoids the small but persistent friction of being gently corrected during standups, conference Q&As, and team calls. Hearing the word a few times locks in the right reading better than reading IPA ever will. Pronounce is a community-maintained dictionary — every entry tagged with a confidence level and (where possible) a citable source.
