Do you know you can watch Chinese space station passing over you? It is probably a whole magnitude dimer than ISS, but still is truly bright, matching that of Jupiter.

I love watching ISS passes. Spot the station, official NASA app and a bunch of others do a fairly good job of predicting it for free. As Chinese counterpart (Tiangong) finishes assembly in 2023 or so, it piqued my interest of viewing it. But most apps (like Skywalk) only offer its prediction and notification as in-app purchases.

As an iOS developer and part time astronomy educator, I coded it up to solve my personal pain points, and I felt obliged to craft Space station passes without monetization in mind to educate the masses!

– Entirely free, no ads, no in-app purchases.

Heavens-above style sky chart

– Optionally sends pass notifications, so that notifies me look up at the right time.

P.S my kiddo loves seeing those "wandering stars" with me haha.

No free app that predicts Chinese space station passes, so I made one!

  1. Super well designed app. Love the mini tutorials. I’m going to feature it on my website MacObservatory.com if that’s ok?
