A photo library worth keeping starts with sorting it.
SpectraSort sorts through thousands of your photos in seconds and surfaces the ones that match your taste. It runs entirely on your device. Nothing leaves your phone.
FAST
Powered by Apple's Neural Engine, SpectraSort processes up to 100+ photos per second on the latest iPhones. A library of 2,000 photos sorts in under 30 seconds.
SMART
Tell it what you're looking for: city scenes, nature, portraits, food, architecture, or up to 3 of any of 8 built-in subjects. Add your own keyword for anything else — your dog, your bike, that trip to Lisbon.
TUNABLE
Every photo is scored across seven quality dimensions: sharpness, exposure, contrast, noise, composition, color harmony, and visual balance. Dial each in individually, slide between technical and artistic, or spin the balance dial — subject-driven on one side, quality-driven on the other.
QUICK START
We ship with three ready-made profiles you can use immediately:
• City & Travel — for the trip photos
• The Outdoors — for landscapes and adventure
• Faces — for portraits, candids, family
Or build your own. Save it. Switch between them.
TASTE PROFILE
Keep using the app, and a Taste profile quietly takes shape — a portrait of your preferences, assembled from the photos you choose to keep and the ones you let go. Use it as-is or as a starting point to fine-tune.
PICKING PHOTOS
After sorting, the photos you're looking for are surfaced to the top. Swipe through your picks the way you'd expect — right to keep, left to let go. Save your keepers to a new album, share the standouts, delete the rest in bulk.
PRIVACY
Everything happens on-device. No uploads, no cloud, no accounts. Your photos never leave your phone.
PRICING
Sorting itself is always free. Upgrade once to save, share, and bulk delete — $7.99 for life.
