Postra Mobile

Postra turns your camera roll into a single flow: find, compose, refine, and export. No tagging required — just open your photo library and let on-device AI understand your photos.

Find the one shot

• Recent, Random, or AI search to surface buried photos fast

• Search by words like "flower" or "sky" with on-device AI text search

• Tap any photo to gather visually similar ones

• Filter freely by camera, lens, and color

Build photo collages

• Grid, Free, and many Design templates for flexible layouts

• Presets for Instagram, X, Threads, Stories, and note aspect ratios

• "Preview" — see exactly how your post will look before sharing

Refine

• One-tap color presets, plus brightness, HSL, curves, and crop

• Copy & paste adjustments to other photos

Finish and export

• Add a caption band with EXIF (camera, lens, aperture, date)

• Print-style finishing with paper texture and drop shadow

• High-quality export at each platform's aspect ratio, ready to share

Privacy first

• All analysis, layout, and export happen entirely on your device

• Your original photos are never modified

• No account, no tracking, no ads

Note: AI text search downloads a search model (~146MB) once on first use. Your photos are never uploaded.

For iPhone and iPad.
