Version 1.2.2
Review by regolith4

Excellent and Fast! - I bought this app primarily to convert SMI files to SRT, specifically Korean subtitle files. If you have a family member who speaks another language, watching American films can be trying—subtitle files are freely avaiolable from multiple sources on the web, but the format tends to be SMI, which doesn’t work well with comon iTunes conversion suites like Handbrake. SRT, on the other hand, works perfectly and doesn’t require a subtitle burn. Finally there’s an easy to use and extremely fast (as in conversion last less than a second) app that does exactly what I need. 5 Stars!
