Apertin

Apertin とは？

Apertin is an ultra-lightweight desktop app that rescues photographers from slow software. Instead of loading heavy 50MB RAW files (.ARW/.CR3/.NEF), it instantly extracts embedded JPEG previews. Combined with a Tinder-style swipe mechanic, it turns photo culling into a game. Swipe right to KEEP, swipe left to TRASH, and use spacebar for a quick 100% focus check. It's completely free, open-source, and 100% local-first. Stop waiting for Lightroom!
