Orbweft Star Trails

Merge photos into star trails

$4.99 · Designed for iPad. Not verified for macOS.

Turn a still sequence into a finished star-trail image. Review frames, choose a trail style, preserve the foreground, then share the image and processing record. Orbweft combines still photographs into star trails or light trails on your iPhone and iPad. BUILD A REAL TRAIL IMAGE Import a fixed-camera sequence from Files or Photos. Full mode keeps the brightest sRGB channel value from each included frame. Comet fades earlier frames toward the last frame; Javelin fades both ends around a brighter middle. Average combines frames equally without alignment. CHOOSE WHAT TO KEEP Review individual source frames and exclude unwanted exposures. Compare the selected frame with the actual stack. Optionally subtract one matching covered-lens dark image and adjust the subtraction amount. Keep the first included frame below a horizontal foreground boundary, with a short feather. Set exposure from -2 to +2 EV. TAKE THE RESULT WITH YOU Export 8-bit sRGB PNG and JPEG, Frames.csv, Session.json, a processing PDF and Readme.txt together in a ZIP. Share the PNG alone or the complete package through iOS. Images are downsampled only, never enlarged, to a chosen 1024, 2048 or 3072 pixel long-edge limit. Source EXIF is not copied into exported images. RETURN TO A SAVED SEQUENCE Source copies and processing settings stay in local saved sessions. Reopen, rename, duplicate and delete sessions. The library starts empty; an optional synthetic 48-frame example is clearly labeled and processed by the same compositor. One upfront purchase. No subscription, ads, account, analytics, tracking or developer-server upload. Use a stationary tripod and matching oriented image dimensions. Excluding frames may leave trail gaps. Orbweft does not capture photos, register or align stars, fill gaps, develop RAW, remove aircraft automatically or create timelapse video. Processing uses decoded 8-bit sRGB values rather than linear-light or HDR integration. Supports JPEG, PNG, HEIC and TIFF stills, up to 120 frames per session and 32 MB per file. Up to 512 MB of source files per session, 20 sessions and 1 GB total library storage. Export packages contain results and processing records, not original-source backups, and cannot restore an editable session. Keep originals separately.
