Auto-captions are never right the first time. A name is misspelled, two lines are merged, the timing drifts by half a second — and most apps give you no way to fix any of it. Subvibe gives you the timeline. Tap a word to retype it. Drag a block to retime it. Split, merge, restyle — then translate the whole track into any of 20 languages and export it as a clean .srt file or burn it straight into the video. Your video never leaves your iPhone — only the audio is used to generate subtitles. Prefer full privacy? Switch speech recognition to on-device mode and work with no connection at all. • SUBTITLE EDITOR — retype, split, merge and restyle every line on the timeline • EXACT TIMING — drag blocks to fix drift and match speech frame by frame • TRANSLATE ON DEVICE — 20 languages, nothing uploaded, no account • AUTO SUBTITLES — accurate speech-to-text, in the cloud or right on your device • BEAUTIFUL STYLES — fonts, colors, outlines, backgrounds, and one-tap designer templates • ANIMATIONS — word-by-word reveal and highlight effects that pop on social • EXPORT YOUR WAY — save video with burned-in subtitles, or export an SRT file • ON-DEVICE MODE — switch speech recognition to your device and work fully offline Perfect for creators, editors, and anyone who wants clean, accurate subtitles without sending their videos to the cloud.

Verdict
The clearest difference is in-app purchases: Smart_Viewer at none against Subvibe's 3. Smart_Viewer also leads on ads (none vs shown) and iOS requirement (7.0 vs 18.0). Subvibe's advantage is update cadence (every 9 days vs every 3 months). On price and device support there is nothing between them.
