Superimpose X is a serious photo editor, and the editor is yours with the app — layers, masks, blend modes, brushes, effects, shadows, text and precision tools, with no subscription to use any of it. When you want more, two studios are built right in and unlock with a subscription: an AI Editor that generates and transforms images, and a true multi-track Video Editor. THE PHOTO EDITOR Build complex edits by hand with the control of a desktop app and none of the complexity. Cut out people and objects, combine images, paint masks, adjust colour, add depth and shadow, then refine every detail. • Layer-based editing with up to 24 layers • Magic Wand, Magic Lasso, brush and shape masks • 18 blend modes and 16 adjustment layers • Non-destructive layer blur and adjustments • 63 photo effects, plus clarity, colour, tone and detail controls • Text and curved text • Motion, Zoom, Spin, Lens and Selective Blur, and gradients • Warp, perspective transform and distortion • Paint, smudge, clone stamp and effect brushes • Shadow and Light Wrap tools • Camera fill with real-time masks and blend modes • Masking Library for reusable cutouts and stickers • Session Library that saves your projects automatically • PSD export with layers • Over a million royalty-free stock photos AI EDITOR Start from a photo, a sketch or a sentence and let AI do the heavy lifting, then take the result back into the layer editor to finish it properly. • Image generation from text • AI editing and inpainting • Background creation and replacement • Outpainting and image expansion • Enhance, relight and repair • Sketch to image • Headshot generation • Face swap • Image to image transformation • Image to video • AI people masking VIDEO EDITOR A real multi-track editor, not a template filler. • Edit video, images, audio and text on multiple tracks • Stack effects and animations for results that are yours • Masks for precise work, including green screen • Track objects through a shot and ramp clip speed • Animate text with elegant presets • Split, trim, rotate and freeze clips • Colour effects, blurs and distortions • Audio EQ, filters and transitions • Royalty-free photos, videos, music and GIFs • Export in a range of formats, including GIF ONE APP, ONE PROJECT The three studios share the same project. Composite a frame in the photo editor and drop it on the timeline. Generate a background with AI and mask it by hand. Pull a still out of a video and edit it as layers. Nothing is exported and re-imported just to move between them.

Is tonight worth setting up for – and from when to when? Astrowetter answers exactly that question. With a score, a time window and an honest statement of how certain it is. ONE APP INSTEAD OF FOUR OR FIVE Until now, finding out whether a night was any good meant keeping several apps and websites open: one for rain radar, one for cloud layers and dew point, one for seeing, one for an overall score – and often a spreadsheet to compare the hourly values. The reason for all the switching: each of these tools shows a single weather model and hides the fact that the others say something different. Astrowetter runs up to four weather models at once (DWD ICON-D2 and ICON-EU, NOAA GFS, ECMWF) and shows how far apart they are. If all four say clear, set up. If they disagree, you see it immediately – instead of finding out at the telescope. MORE THAN WEATHER Astrowetter does not judge cloud cover alone. Transparency, fog risk, wind speed and moonlight go into the score as well. So you see at a glance whether the night suits galaxies, emission nebulae, the Milky Way, or the moon and planets. The recommendation sits right under the verdict and the time window. THE NIGHT BAND The whole night from dusk to dawn in one picture: cloud cover as the median of the models with their spread behind it, and below it low, mid and high cloud, seeing and the moon. The observing window is marked in green. WHAT'S INSIDE • Verdict with score, time window and confidence ("4 of 4 models say clear") • Seven nights at a glance • Radar film of the last two hours with 50 and 100 km rings, then the forecast cloud cover hour by hour until morning • Seeing in arcseconds, estimated from the jet stream and air layering • Dew point spread, fog risk and wind – so your optics stay clear and nothing shakes • Moon times: phase, rise and set with their compass direction, countdown to new moon and full moon • Sun times: sunset and sunrise with their direction, plus the start and end of astronomical darkness • Light pollution on a zoomable map, in mag/arcsec² and as a Bortle class, plus the way to the nearest darker sky • Planets with altitude, best time and direction • A compass for moon, sun, planets and the Milky Way: turn the phone until the symbol turns green — then you are facing exactly right • Favourites for several observing sites: switch at the top with a swipe • ISS passes with the track on a world map – green where it is visible from your location • Milky Way: when and how high the galactic centre stands • Reminders for good nights, optionally only for "good" or "very good" • Widgets for the Home and Lock Screen • Shooting tips for the Milky Way, ISS, planets, moon, star trails, galaxies and nebulae • Exposure calculator using the NPF rule, so your stars stay round HONEST, NOT PRETTIED UP Seeing is estimated, not measured. The Bortle class is derived from satellite data. Forecasts beyond two or three days are uncertain – the model spread usually shows that by itself. The two high-resolution DWD models cover Central Europe and Europe respectively; elsewhere the app works with the remaining models and says so. YOUR DATA No account, no ads, no tracking, no subscription. Your location is only requested when you tap "Current location". Sun, moon, planets, Milky Way and ISS are calculated on the device. Maps and place search come from Apple Maps, weather data from Open-Meteo. All sources are listed in the app under "Info". English, German and Spanish. For iPhone and iPad.

Verdict

The call

The clearest difference is in-app purchases: Astrowetter at none against Superimpose X's 8. Astrowetter also leads on review sentiment (100% vs 86%) and price ($2.99 vs $4.99). Superimpose X's advantage is chart position (#21 vs unranked) and iOS requirement (15.0 vs 26.5). On update cadence, ads and device support there is nothing between them.
