Orbit vs Co-Star: Which Astrology App Fits You?
Co-Star is a social daily-horoscope app; Orbit is built to compare two birth charts in detail and explain how they relate. They overlap on compatibility, but they start from different questions: Co-Star asks "what does today look like for me?", Orbit asks "how do you and this person really fit?"
We make Orbit, so we have tried to describe Co-Star fairly from its public information. Orbit's iPhone app is not on the App Store yet; the reading is available on the web.
The short version
| Co-Star | Orbit | |
|---|---|---|

| Compatibility | Add friends to see how you relate | The central feature |
| Tone | Short, blunt, deadpan | Plain-language explanations of each angle |
| AI | Automated templated text | AI-written reading plus an AI astrologer for questions |
| Adding a friend | Friends join the app | A link lets them add their own birthday |
| Availability | On the App Store | On the web now; iPhone app coming |
Where Co-Star is strong
Co-Star has a distinctive voice and a daily habit built around short, personalised notes. The social layer, where you see friends' charts alongside yours, is part of the appeal. If your goal is a quick daily check-in, it does that well, and it is established and widely used.
Where Orbit is different
Detail in the comparison. Orbit calculates planet positions from the exact minute and place of birth, then looks at the angles between the two charts (the method described in Synastry Explained) and explains each in plain language.
Follow-up questions. The AI astrologer answers questions using your Sun, Moon and rising sign and the current sky, so you can ask "why do we argue about this?" and get an answer grounded in your charts.
Low-friction invites. If you do not know someone's birth details, you can send them a link and they enter their own.
A daily reading too. Orbit also gives a daily reading based on your own chart, so it covers the same daily habit.
Who should choose which
- Choose Co-Star if you want a quick, social, daily habit and enjoy its tone.
- Choose Orbit if you have a particular person in mind and want to understand the relationship in detail, and prefer to ask questions rather than just read.
- Use both if you like the daily note and also want a detailed comparison.
What to check before you pick any astrology app
Whichever app you try, these questions matter more than the marketing:
- What happens after the free tier? Note what is locked, how often it renews, and what the weekly, monthly and yearly options really cost.
- How do you cancel? Subscriptions bought through Apple are managed in your Apple ID settings; cancel before the renewal date if you do not want to continue.
- Who writes the interpretation? A human astrologer, a template or an AI. Each has strengths; none is a prediction.
- How is your birth data handled? Look for a clear privacy policy. Orbit's is on the privacy page.
- Does it explain its method? Good apps show you the planets and angles behind a result so you can check them. Our method is on the about page.
If you are comparing Co-Star with Orbit specifically, trying each one's free features with the same two birth charts is the quickest fair test.
Price and terms
Co-Star is free to download with paid tiers. Orbit Pro plans are on the pricing page. Prices on the App Store change, so check each listing and the renewal terms.
A fair note
Neither app can predict how a relationship will turn out. Astrology is a tool for reflection and is not scientifically validated as a predictor of relationship outcomes. Treat any comparison as a conversation starter.
