ChronoFix is a beautiful native macOS app to fix, shift, copy and rename file timestamps — including EXIF metadata and video creation dates — in bulk.

Hi PH! 👋 I'm Tom, and I built ChronoFix after a two-week trip to Japan where my camera stayed on Amsterdam time — 3,000 photos, all 8 hours off, interleaved wrongly with my iPhone shots. The Terminal fixes (touch, SetFile, exiftool) all work, but none of them show you what's about to happen to 3,000 irreplaceable files. ChronoFix is built around a live before/after preview: every file shows its current and new dates side by side before you commit, and one click reverts the whole operation afterwards — including the embedded EXIF/video dates. Under the hood it's 100% native Swift/SwiftUI, works fully offline, and writes metadata losslessly — image pixels and video streams are never re-encoded. Free for up to 10 files per operation (every feature included), one-time $9.99 purchase for unlimited — no subscription, ever. I'd love to hear the weirdest timestamp disaster your library has survived. AMA!

Congrats on launching ChronoFix! The idea behind fix photo & video dates on your Mac — in bulk, losslessly is compelling, especially because the benefit is immediately clear to the people who need it. Wishing you a strong Product Hunt launch!
