About this app

Picastro — Social media for astrophotography

Picastro is a purpose-built social platform for astrophotographers and astronomy enthusiasts.

No noise. No compression. No algorithms deciding what matters. Just real people, sharing real images of the night sky.

Whether you’re capturing your first star trails or processing a deep 20-hour narrowband image, Picastro gives you a place to share your work, learn from others, and actually enjoy the process.

Your images in full quality. Always!
Astrophotography takes time, patience, and precision. Your images shouldn’t be reduced to blurry, compressed versions of your work. Picastro preserves your images in high resolution — what you upload is what people see.

A real global community — not a content machine.
No bots. No fake accounts. No chasing likes. Picastro is built around a genuine community of astrophotographers who want to share, improve, and support each other. It’s not about attention. It’s about progress.

Learn naturally as you go. Every image on Picastro carries context. With StarCards©, you can see exactly how an image was captured — telescope, camera, filters, exposure time, and more. No gatekeeping. No guesswork. Just real insight from real people.

Built for beginners in astronomy and astrophotography and experts alike.

Starting out? You’ll find a welcoming space where you can share your first images without feeling out of place. More experienced? You’ll discover high-level work, detailed setups, and meaningful discussions. Everyone starts somewhere. Picastro meets you there.

Designed for mobile and tablet. Built for simplicity.
Picastro isn’t a complicated web platform adapted for your phone. It’s a native mobile experience designed to be fast, clean, and easy to use — so you can spend more time exploring the night sky and less time figuring out how to post.

Safer image sharing
Your work matters. Picastro includes built-in protections designed to make your images harder to scrape, copy, or misuse — so you can share with more confidence.

No ads. No clutter. No distractions. Picastro is subscription-based by design. That means no adverts, no spam, and no algorithm-driven content feeds. Just a clean, focused space for astrophotography.

Ratings and reviews

Nice app geared towards astrophotography with pleasant UI design elements and intuitive feel. Uploading images is streamlined with options to be technical with your entry or more lighthearted when you just want to share something quickly. Having a trial period to try before you buy is a welcomed addition. User base feels small with maybe a dozen repeat members that interact. So if you are looking for reach this may not be it...Yet. Given the small footprint, current pricing feels high.

Developers locked down the app so you cannot have Developer Mode, Rooting, etc. anymore with the most recent update. They claim that Dev Mode is no longer necessary because the app is "92% faster" and shouldn't need to change animation speed in dev mode. I noticed little to no change on this claim. Go figure when phone animation speed has no effect on apps anyways. It's a great app for Astro, but a very disappointing change for things on Android. No, I'm not turning it off for one app, sorry.

A really greater app that even provides free monthly datasets (spacetime pictures). The only minor thing I'd love to see is a way to copy text within the app.
