ReeXpose is the best app for long exposure photography on the App Store. Designed by professionals for professionals, ReeXpose closes the gap between your iPhone and a DSLR camera, allowing you to shoot long exposure photos in RAW. All without the need for additional ND filters! Select your capture mode, adjust your exposure, chose your capture duration and ReeXpose will do the rest. The result will be a single, 12-bit DNG file editable in your favorite editing software. Use the “motion blur” mode to make people disappear, smooth the movement of clouds, or give running water a characteristic silky appearance. Use the “light trails mode” for stunning star trails or to transform moving cars into gorgeous rivers of light. Enjoy the flexibility of full manual controls and the extended dynamic range given by RAW files. ReeXpose is brought to you by REEFLEX, the small studio behind the development of Reeflex Pro Camera and ReeHeld. — MAIN FEATURES — • RAW capabilities for long exposure*/**/*** • Motion blur & Light trails modes • Extended capture time ranging from seconds to minutes, hours, and Bulb (unlimited) • Full manual controls for ISO, shutter speed, focus, and white balance • Live preview: watch the RAW photo developing on the screen • Interims results: allows taking intermediate photos during a long capture • Parallel bracketing: allows capturing 2 photos at different selected exposures for HDR bracketing in post-production • Exposure guides like histogram and zebra stripes • Focus peaking • Apple Watch integration for remote shutter • Photo backup in the File app • Gyroscopic tiltmeter and Grid (rule of thirds) • GPS location in the photo’s metadata • Multi-Language support • Blazing fast processing & saving time (1ms) • Lock Screen Widget for quick access • Tap-to-focus (Auto-focus) — ACCESSIBILITY — • Color-blind users can tune the app to suit their needs best, customizing the UI and color coding. — IMPORTANT REMARKS — • Note #1: *The RAW format is not supported for the ultra-wide camera on devices older than the iPhone 12 series (this is a limitation given by the manufacturer - Apple) • Note #2: **As usual for long exposure, you must use a tripod and keep the phone as steady as possible. The app does NOT stabilize the images automatically. If this is what you're looking for, then please have a look at our other app (ReeHeld) • Note #3: ***Bayer RAW images, which are the standard in professional photography, necessarily require editing in post-production in order for you to obtain a properly elaborated photo. The RAW image captured differs from what you see in the live-preview when shooting, as the live preview is based on the elaborated live output which is in JPG. Hence you might notice differences in what you see on the screen when shooting vs the final DNG image (Bayer RAW). We, therefore, suggest fine-tuning your exposure by manually adjusting SS and ISO, and taking several shots in order to find the best settings for your desired shot. — GET IN TOUCH — • We'd love to hear from you!

Browse the Moon, star fields, star clusters, nebulae and galaxies, including Messier objects and showpiece deep-sky targets. Planets are included for locating and framing. Detail on planets needs added optics, so Tonight does not recommend them for automatic phone capture. CAPTURE Aim, align and hold still.

Verdict

The call

The clearest difference is review sentiment: Astrosimo at 100% against ReeXpose's 45%. Astrosimo also leads on rating (5.0 vs 4.3) and update cadence (every 2 days vs every 6 weeks). ReeXpose's advantage is ratings volume (457 vs 1) and iOS requirement (18.0 vs 27.0). On price, ads, in-app purchases and monetization model there is nothing between them.
