Subtitle editor: SRT and VTT

Fix subtitle text and timing on your Android phone. Open an SRT or WebVTT file, correct a line, check the timing and export a new copy.

Editing, checks and every export are free. Search and replace repeated text, shift timing earlier or later, and undo the last change. Timing starts with the selected cue only; choose ripple mode explicitly to shift later cues. Previews show how many cues will change.

Check overlapping cues, short gaps, reading speed, crowded lines, empty cues and invalid times. Findings identify the affected cue without silently changing your file. You can select a local video to compare the subtitles with playback, but editing and export also work without one.

Private drafts retain saved edits and unfinished cue text for recovery. Undo history restarts after recovery. Exports create a new file rather than overwriting the original. The app reads the exported copy back before confirming it.

A one-time Pro purchase adds cue split and join, range stretch and batch conversion of up to 50 SRT or WebVTT files. Restore purchases is included. Google Play shows the local price before purchase; there is no subscription.

Subtitle processing stays on your device. There are no ads or mandatory accounts. Sharing sends the exported file only to the app you choose; purchases use Google Play.

Supports SubRip and WebVTT, not ASS or SSA. This is an editor for existing subtitle files, not an automatic caption generator. It does not transcribe audio or display a waveform. Malformed or unsupported input may be refused rather than exported with damaged text.
