AstroShader vs ClipKit

One-time purchase. No subscription. AstroShader is an astrophotography app for capturing, stacking and editing. All you need is a stand, tripod, telescope or rock (to lean your phone on). AstroShader lets you align and stack live during the image capture process. You can also align and stack images from you Photos library. No need to transfer images to a computer to align and stack them separately (but there is a built in intervalometer if you need it). To take an image follow these steps: • Use a stand, tripod, telescope mount (or lean your iPhone on a rock). • Zoom in on stars and set focus manually, or use autofocus. • Set the exposure time, ISO and white balance, or leave to auto-exposure. • Set the number of exposures to be automatically aligned and stacked. • Calibrate your images from the edit tools. • After the capture is complete you can edit and save your image—including as 16bit TIFF. • You can open images directly to use the edit tools in AstroShader - rather following a new image capture. Image capture options include: • Number of exposures to be aligned and stacked • Exposure time • ISO • White balance • Camera type • Countdown timer • Manual focus • Pause the capture to reposition iPhone or telescope Edit options include: • Stretch image • Background extraction • Dynamic background extraction (DBE) • x5 Histogram curves for fine tonal adjustment • x3 sharpen layers each with radius and intensity with layer blending rather than chaining • Brightness (low light enhancement) • Saturation • Black point • Temperature • Tint • Save format options; HEIF, PNG, JPEG, TIFF

ClipKit is the privacy-first video utility for iPhone and Mac. Every operation runs locally on your device, on the Apple Neural Engine and Apple silicon — no servers, no uploads, no accounts. EIGHT ONE-TAP TOOLS • Social Ready — auto-trim silence, reframe to 9:16, and normalize audio for vertical platforms. • Neural Captioning — generate accurate, on-device subtitles and burn them in, or save an .srt sidecar. • Studio Voice — strip wind, traffic, and hiss to bring vocals forward. • Privacy Redaction — automatically detect and pixelate every face, frame by frame. • Metadata Scrubber — strip GPS coordinates, device names, and EXIF data with one tap. • ProRes Compressor — convert massive 4K ProRes files to high-quality HEVC at hardware speed. • Instant Recap — pick the best moments from long footage and assemble a 15-second teaser. • Background Magic — blur or replace the background using on-device person segmentation. PRIVACY BY DESIGN ClipKit works fully offline. Drop it into airplane mode and every feature still works. There is no telemetry, no cloud, no analytics. Your videos never leave your hardware. SECURE VAULT Save processed clips into a biometric-locked vault, encrypted with CryptoKit AES-GCM and a key gated by Face ID, Touch ID, or your Mac's biometrics. FOUR WAYS IN Pick from Photos, choose a file, drag-and-drop on Mac, or share a video from any other app. ClipKit handles the rest. Built natively for Apple silicon. Optimized for iOS 18 and macOS 15.
