User Reviews
Pros
- Rich feature set and depth with extensive astronomy tools and mapping, enabling deep exploration of stars and galaxies.
- Real-time sky following and augmented reality capabilities, enhancing interactive learning.
- Clean UI and beginner-friendly design that makes the app accessible to newcomers.
- Strong educational value with comprehensive content and visuals that aid teaching and exploration.
Cons
- Subscription pricing and perceived lack of added content; users feel they’re paying for minimal new features.
- Time range limitations to 1600 AD (and re-installation restrictions) that limit long-term simulations.
- Navigation/compass accuracy issues (about 20° off) affecting real-world pointing and usability.
- Data accuracy concerns after updates (inaccurate solar and lunar data) and occasional reliability problems.

It doesn’t navigate properly. I can point my iPhone towards the moon stars or planets. It’s always about 20° off. I’ve tried to calibrate the compass. With these large errors, the app is useless.

Too much reliance on Constellations
by Da*****, 2025-02-13
Update 01/11/2022: So after about a year of the subscription fee I'm disappointed to say there's been nothing added since my original review. It makes me wonder what exactly I'm paying for. It seems like they just want to resell me the app over and over again without giving me anything in return. I understand that apps require upkeep and without it they quickly become abandoned, which in turn means they inevitable quit working as they fall further and further behind. On the other hand I want more than just maintenance updates if I'm gonna be paying a hefty annual subscription fee. I guess time will tell but I doubt I'll be subscribed for much longer if no further content is ever offered. It's a shame too because I really want to support science apps but I also want to feel I'm getting my money's worth. This is a great app but there's always room to grow. Do the devs agree?
When the devs first released this new version of their astronomy software, Redshift, I was excited. I've spent countless hours with their old version exploring and reading everything it had to offer. I quickly preordered the new version and waited for it to be released while wondering what new treasures were in store. Then after it was finally released came the disappointment. While the new Redshift looked more polished there seemed to be very little in terms of new content and what seemed even worse to me at the time was that now it came with a subscription fee. I was tempted to rush to the app store to write a scathing review but I decided to wait to see if anything new might still be coming. Ultimately, it was the right move. Adding the ability to explore different galaxies like you would for objects inside the Milky Way is a fantastic new addition that really expands the feeling of depth to this model universe. I do wish you had more range to view the universe on the grandest scale but you are only able to zoom out 100kpc away from any galaxy. I would like to be able to rotate the universe from a greater distance and then zoom down into a random galaxy. While I don't expect to be able to see objects in the far away galaxies it would be cool if eventually they added certain objects that we can observe in the nearby galaxies such as the LMC, SMC and Andromeda. Hopefully, that's why they have subscription fee now, to have ability to keep adding content. I can't wait to see what develops but for now it's a solid 4 stars with potential to be a perfect 5. Thanks to the devs on their awesome astronomy app!
