Features
Read full description

SRT Subtitle Toolbox Mobile is a professional iOS workflow for SubRip (SRT) files. Built for subtitle teams, translators, editors, and multilingual video creators, it brings desktop-grade subtitle production to iPhone and iPad: merge, split, align, re-segment, and quality-check—without leaving your device. All processing runs locally. Your files stay on the device. No cloud upload is required, so client assets and unpublished content remain private. KEY CAPABILITIES 1. Combine Import multiple SRT files, join them in order, and stack timelines automatically into one delivery-ready file. 2. Split bilingual Separate a two-language SRT into two independent files for distribution, review, or further translation. 3. Merge bilingual Combine source and translation SRTs into a two-line bilingual file (source on top, translation below). 4. TXT to SRT / SRT to TXT Turn plain or bilingual text into timed SRT for your NLE, or strip timing and export clean text for translators. 5. Match translated scripts Pair a timed original SRT with an untimed translator draft to produce a timed bilingual file—built for real production handoff. 6. Text filter Keep Chinese, English, or the inverse, drop empty lines, and export SRT. 7. Pinyin / Zhuyin Convert cues to pinyin or Zhuyin, optionally with tones and the original line. 8. Time shift Move the entire timeline earlier or later to fix sync. 9. Smart split Re-segment Whisper and similar ASR output in Chinese and English so translation and layout stay clean. 10. Crop Keep only the time range you need. 11. Reformat Split long cues by character limit, deduplicate adjacent lines, and flatten multi-line text. 12. Prefix / suffix Batch-add speaker names or labels to selected or all cues. 13. Interval cleanup Close gaps that are too small between adjacent cues. 14. Find & replace Run multiple replacement schemes across multiple files to keep terminology consistent. 15. Statistics Count characters, speech rate (CPS), and lines, and highlight cues over your threshold before delivery. WHO IT’S FOR Subtitle groups, localization teams, freelance translators, course and short-form creators, and anyone who needs a reliable SRT finish on the go. EXPORT UNLOCK The app is free to use.
