About this app
Your night-sky photos deserve an editor that understands stars.
Generic photo editors smear stars into blobs, crush the Milky Way into mud,
and turn dark skies grey. Starro is built only for astrophotography — every
slider, preset and processing step knows the difference between a star, sky
glow and noise.
STAR-SAFE EDITING
• Built-in star detection protects pinpoint stars while you push exposure,
contrast, dehaze and structure
• Light, Color and Detail controls tuned for night-sky dynamic range
• Fully non-destructive: stack multiple edit passes, revisit or remove any
of them later
ONE-TAP ASTRO PRESETS
• Milky Way, Nebula, Star Field, Moon and Deep Sky starting points
• Every preset is just a starting point — fine-tune everything
SEQUENCE & BATCH PROCESSING
• Import whole capture sequences and process them in one run
• Exposure normalization evens out frame-to-frame brightness drift
• Background processing with progress notifications — leave the app and
come back to finished images
WORKS WITH TRAILIUM
• One tap sends processed frames to Trailium to build star-trail images and
timelapse videos — no export/import dance
• Made by the team behind Trailium and Intervals: a complete phone
astrophotography workflow from capture to final image
PRIVATE BY DESIGN
• 100% on-device processing — your photos never leave your phone
• No account, no ads, no tracking
• Free
Whether it's your first Milky Way shot or your hundredth deep-sky sequence,
Starro turns the frames you captured into the sky you remember.
