## What is SRT Subtitle Toolbox Mobile?

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 No cloud upload is required, so client assets and unpublished content remain private.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.
