Co-Star did something no other astrology app had managed: it made birth charts a group chat topic. The stark black and white design, the blunt push notifications, the way it turned "what's your rising sign" into a normal first date question. Credit where it's due. But if you're searching for alternatives, something stopped working for you, and it's usually one of three things. The AI-written one-liners started to feel random, or a little cruel for 9am. The chart turned out to be shallow, because once you've read your placements there isn't much left to study. Or the whole detached, clinical vibe just wore thin.
All fair complaints. Below are five apps ranked by what they actually fix, with honest cons for each, because none of them is perfect either. If you want the wider field beyond Co-Star refugees, we also keep our full top 10 astrology apps ranking updated.
TLDR: the best Co-Star alternative overall is Personology. It keeps the daily habit that made Co-Star sticky (daily readings, streaks, an AI guide) but swaps the one-liners for actual depth: your full birth chart crossed with your MBTI type, producing readings that feel written about you rather than at you. Free to start, iPhone only for now.
| App | Fixes what about Co-Star | Free tier | Best for |
|---|---|---|---|
| Personology | Shallow, impersonal readings | Free to start, premium adds the full Blueprint | Depth plus a daily practice |
| The Pattern | Vague daily blurbs | Yes, and it's generous | Long, emotional self-analysis |
| CHANI | The cold, cutting tone | Yes, weekly readings | Warm, reflective guidance |
| TimePassages | Thin chart data | Yes, basic natal chart | Actually learning astrology |
| Sanctuary | No humans anywhere | Yes, daily horoscopes | Live readings with real astrologers |
1. Personology: the depth Co-Star never had
Co-Star's core weakness is that its readings describe a Scorpio, not you. Personology attacks that head on. It crosses your natal chart with your MBTI personality type, which gives it 192 possible lenses (12 signs times 16 types) instead of 12. The app's own line sums it up: a Scorpio INTJ and a Scorpio ESFP share a sky, not a life. Having used both, that framing holds up in practice. Two people with the same big three get genuinely different readings here.
The centerpiece is the Blueprint, a seven chapter written reading covering your core patterns, career paths, relationships, friends and family, routines and habits, and your growth edges. It reads like a long profile of you, not a caption. Around it sits the daily layer Co-Star users will recognize: daily readings tied to your specific placements, tarot pulls, journal prompts, alignment percentages and streak tracking. Luna, the built in AI guide, can see your chart and your type, so asking it a question beats asking a generic chatbot that knows nothing about you. You also get a full birth chart with Sun, Moon, rising, every planet from Mercury through Pluto and house placements, romantic compatibility built on synastry plus psychology, a Friends feature for comparing Blueprints, and moon phase guidance for setting intentions across the lunar cycle.
Cons, honestly: it's iPhone only right now, with Android and web on the roadmap, so Android users are stuck waiting. The MBTI crossover is the whole point, which means purists who think personality typing has no place next to a natal chart will hate it on principle. And the complete Blueprint sits behind the premium subscription, though the free start is enough to tell whether the approach clicks for you. Try Personology here.
2. The Pattern: longer, heavier, more emotional
When people say they want "a deeper Co-Star," they usually mean The Pattern. Its readings run paragraphs, not sentences, and they focus on psychological patterns and timing cycles rather than planet talk. It barely uses astrology vocabulary at all, which is either liberating or maddening depending on who you are. The free tier is genuinely generous, and the bond readings between two people are among the most detailed anywhere.
Cons: it can be a lot. The app loves warning you that a difficult cycle is coming without offering much practical advice for it, and the jargon free approach means you finish a reading with no idea which transit caused it, so you can't go study further. We wrote a full head to head in The Pattern vs Co-Star, compared if you're choosing between exactly these two.
3. CHANI: the anti Co-Star tone
If your problem with Co-Star was the vibe, CHANI is the correction. Built by astrologer Chani Nicholas, it's warm where Co-Star is cutting: weekly readings, guided meditations, journal prompts and ritual suggestions tied to what's happening in the sky. The writing is the best in the category, full stop. It treats astrology as a tool for self inquiry rather than a personality verdict handed down from an algorithm.
Cons: the subscription is one of the priciest on this list, there's no compatibility feature at all (a deliberate choice, but people miss it), and the pace is slow by design. If Co-Star's quick dopamine hits were the part you liked, CHANI will feel like homework for the first week or two.
4. TimePassages: for people who outgrew the app format
Some Co-Star users don't want better vibes. They want more data. TimePassages is closer to professional chart software than to a horoscope app. You get the full chart with detailed interpretations for every placement and aspect, real time transit tracking, and enough reference material to teach yourself astrology instead of being handed conclusions.
Cons: the interface looks a decade older than everything else here, there's nothing social about it, and the good stuff (advanced charts, extra report types) costs money through in app purchases. It's a study tool, not a daily companion, and it makes no apologies for that.
5. Sanctuary: actual humans on demand
Sanctuary's fix for Co-Star is simple: talk to a person. The free layer at Sanctuary is a decent daily horoscope with a playful, meme literate tone, but the real product is live chat readings with professional astrologers, plus tarot and psychic readers, whenever you want one. For a specific question, a breakup, a job offer, a move, a human who reads your chart and answers follow ups beats any generated text.
Cons: those readings cost real money and sessions are timed, so it gets expensive fast if you get hooked. The free horoscopes are fun but no deeper than Co-Star's. Think of it as astrology as a service rather than an app you live inside.
What Co-Star gets right
Fairness matters here, because Co-Star earned its popularity. The chart math is legitimate and draws on NASA JPL data, and the app made precise birth time astrology mainstream when most horoscope apps were still sun sign only. The design is genuinely iconic. The friend comparison feature made astrology social in a way nothing before it did. And plenty of people actively like the blunt notifications; getting roasted by the sky at 9am is a feature, not a bug, for some of us. If the one-liners still land for you, keep it. The apps above are for the day they stop.

Frequently asked questions
Is Co-Star actually inaccurate?
No. Its chart calculations are solid and pull from NASA JPL data. The complaints are about interpretation, not math: short, machine assembled fragments that can feel random, contradictory or needlessly harsh. Accuracy was never really the problem people were having.
What's the best free Co-Star alternative?
The Pattern has the most generous free tier of the established picks. Personology is also free to start, so you can see whether the sign plus personality type approach fits you before paying, with the complete seven chapter Blueprint reserved for premium subscribers.
Why are Co-Star's notifications so strange?
They're assembled by software from short fragments written in house, then pushed with no context. That's intentional, since provocation drives screenshots and shares. Some land as poetry. Others read like a fortune cookie having a bad day, and there's no way to tune the tone.
Do any of these alternatives work on Android?
The Pattern, CHANI, TimePassages and Sanctuary all run on Android. Personology is iPhone only for now, with Android and web versions on the roadmap, so Android users should start elsewhere on this list and check back later.
