Does TransFloat work with every app?
No. Cross-app translation relies on the iOS system broadcast and audio made available by the source app. Some apps or protected content do not provide usable audio.
Which features require TransFloat Pro?
Cross-app translation, audio file translation, Picture in Picture subtitles, and optional iCloud sync require Pro. Check the app for current prices, plans, and any usage limits.
Can I read both languages at once?
Yes. Bilingual subtitles show the original words and translation together. You can also choose an original-only or translation-only layout.
Does every language and iPhone work?
Availability depends on your device, iOS version, language pair, and installed speech and translation resources. Check language availability in the app before starting.
Can I save and export subtitles?
Yes. Revisit saved tasks in your translation history and export SRT or TXT with original, translated, or bilingual text.
Are translations always accurate?
No. Noise, accents, overlapping speakers, and specialized words can affect results. Review important details against the original speech.
