What's New in Astro Stacker

2.0.4

July 9, 2026

This update is all about reliability and a smoother editing experience: • Fixed image import — selecting photos from your Photo Library or Files now imports reliably, every time. If something can't load, you'll get a clear message instead of a silent failure. • Faster, more stable post-processing — one-tap style presets (Natural, Nebula Pop, Cosmic Drama, Scientific) now each give your image a distinctly different look, with a live preview as you tune. • Redesigned Analysis screen for a cleaner overview of your dataset before stacking. • Clearer next steps after stacking, with quick access to post-processing, save, and export. • Improved account sign-in so your stacking history and Pro subscription stay tied to your account and sync across your devices. • In-app feedback now sends reliably — tell us anything via Settings → Send Feedback. • Various bug fixes and performance improvements. Thanks to everyone who reported issues — this release fixes several of them directly. Clear skies!

User reviews

Would be great if it worked

This app has the potential to be the best for astrophotography and image stacking if it actually stacked your images without crashing. There are a multitude of settings and adjustments that you could make that you wouldn’t find anywhere else and it’s layout is great but anytime I attempt to stack any number of images (even two on the lowest settings), every time it gets to 65% it automatically crashes. I’m not willing to jeopardize any money on upgrading my free subscription to find out if it works then I doubt it. Make it work and it’d be well worth the money though.

Response from developer

hi thanks for your feedback, we had some issues with that version and have since upgraded it please check it out would love to offer you some more credits to really test all the settings!

nope

App makes it so you sorta have to pick a paid option to do anything. tapping ‘free’ when a paid/free choice pops up does not work. I paid the seven bucks. It isnt worth the seven bucks I paid for it. Now I have to wait for it to show up on my itunes account or whatever to request a refund. It isnt siril. It isnt pixinsight. It couldnt produce results with known good input. skip it. would have rated it one start except nobody takes a one start serious.

Crash. Crash. Crash

Simply crashes every time you try to stack anything. Garbage.
