What it does
SERAPH gives photos the proportions designers and photographers have been using for centuries — the golden ratio (φ ≈ 1.618). Drop in a photo, drag the φ-locked crop frame, and export. That’s it.
Key features
- Golden-ratio crop frame, locked to φ — drag, pinch, rotate, never lose the ratio
- Composition overlays — golden gridlines, golden triangle, rule-of-thirds-φ
- Batch mode — load a folder of photos, crop them all, export as a single ZIP
- Smart suggestions — φ-anchored crop variants generated from the source image (Pro)
- Custom ratio input — type any number, snap to φ on demand (Pro)
- Direct save to Photos — one tap, no extra dialog
- Native iOS share — AirDrop, Messages, Instagram, anywhere
- iOS Share Extension — share a photo to SERAPH from any app to start cropping immediately
Free & Pro
The free tier includes 10 watermarked crops per month, with single-photo cropping, standard aspects, and the basic golden-rectangle overlay. SERAPH Pro unlocks unlimited crops, no watermark, all composition overlays, smart φ-anchored suggestions, custom ratio input with φ snap, batch mode with session resume, and export presets.
Pro is available as a monthly subscription ($4.99/mo), an annual subscription with a 7-day free trial ($29.99/yr), or a one-time Lifetime purchase ($79.99).
