Celestium for Android.
Celestium is coming to Google Play. It runs the same on-device astrology engine as the iPhone app; real ephemeris, computed on your phone, nothing sent to a server.
Leave your email and we'll tell you the day it lands. Your first week of Premium is on us; the code will be in that email. It's a free trial, so cancel any time before it renews if it isn't for you.
You're on the list. 🌙
We'll email you the day Celestium lands on Google Play, and your code for a week of Premium will be in it. Nothing between now and then.
On iPhone, iPad, or Mac today? Get Celestium on the App Store →
Rather follow along in the meantime? The weekly sky notes live on Substack.
The Android beta is here — a direct download while we finish the Google Play listing. Same real ephemeris, computed on your device.
Version · arm64 phones · Android 9 and up · about 150 MB
How to install
- Tap Download above on your Android phone.
- Open the downloaded
.apkfile (check your notifications or Downloads). - If Android asks, allow “install from this source” — this is expected for apps not yet on the Play Store. You can turn it back off afterward.
- Tap Install, then Open. That's it.
No auto-update yet — check back here for new versions. This is an in-progress beta, so a few things from the iPhone app aren't here yet. Found something? Tell us.
