Through v. 7.1, Submerge was stable and effective, offering an easy-to-use subtitling application that could be adapted to anything from iPods to TVs. What's more, the price is right at $9.

The latest version, 1.8.1, has a few problems. The subtitles may appear in the very center of the screen, not the bottom like before. Processing clips isn't as smooth as past versions. Just as troubling, but for a different reason, customer service is never responded, or even acknowledged inquiries. Using their online support form was useless.
