Open ASS on Phone

ASS is an advanced subtitle format with style and event sections.

• Phone viewers usually show subtitle files as raw text.
• Timestamps and cue boundaries are hard to scan without a structured view.
• A local preview is enough to confirm language, timing, and text content.

OpenOnPhone is for quick local inspection. It does not replace the original professional app for editing, conversion, exact layout, formulas, measurements, security review, or full workflow features.
