TL;DR: Different jobs, not the same app
If you strip the marketing away, Raka and Co-Star are trying to do two different jobs. Co-Star is a daily personality companion. It gives you a sentence in the morning, a nudge in the afternoon, and a way to see how you and your friends line up. It is a social object as much as it is an astrology app.
Raka is a reflection practice. It gives you a natal chart, a growing tarot vocabulary, and an AI reading coach you can actually talk to. It is closer to a private journal with a teacher inside than to a feed of witty forecasts. Nobody sees your readings but you.
This distinction matters because comparing the two on raw feature count is misleading. Raka has tarot and a full learning path that Co-Star simply does not offer. Co-Star has a social graph and a distinct writing voice that Raka does not try to match. Neither is trying to be the other.
So the honest question is not which one is better in the abstract. It is which job you actually want the app to do for you in 2026 — get through the day with a smart quip, or build a slow, personal practice you can lean on when things get heavy.
Pricing and free tiers compared
Raka has a clear two-tier model. The free tier gives you a full natal chart, daily readings, and enough of the tarot experience to know whether the app is for you. The Mastery subscription is $9.99 per month or $79.99 per year and unlocks unlimited AI chat, all five premium spreads, and the entire 90-lesson learning path.
Co-Star is famously free to install and free to use for most of what people love it for: the daily horoscope, the natal chart, and friend compatibility. It layers paid options on top for deeper readings and one-off chats with human astrologers, and those prices vary by market and offer.
On a pure cost basis, Co-Star is cheaper if you only want a daily line and a compatibility check. Raka is priced like a small course or a journaling subscription, and that is the honest framing: you are paying for depth of interaction, not for a forecast.
Neither app pushes big one-time purchases the way older astrology apps did. Both let you try before you commit, and both make it easy to cancel. If you are cost-sensitive, start free on either side and only upgrade once you know what you actually use.
Tarot: the biggest single difference
This is the clearest gap in the whole comparison. Raka is a tarot app as much as it is an astrology app. It ships with five premium spreads — daily draw, three-card, Celtic Cross, decision, and shadow work — and an AI reading coach that walks you through interpretation instead of just naming the cards.
Co-Star does not do tarot. It has never claimed to. If you want tarot inside Co-Star, you are out of luck; you would need a second app. That is not a knock on Co-Star, it just means the two apps are not substitutes for a tarot practice.
Raka also includes a 90-lesson learning path that teaches the cards, the suits, elemental correspondences, and how tarot and astrology speak to each other. Over a few months, that turns a beginner into someone who can actually read for themselves without leaning on the app for every meaning.
If tarot is even a minor interest for you, this alone tips the decision. Raka replaces both a starter tarot deck plus book and a daily astrology app with one tool. Co-Star stays in its lane as an astrology companion.
Astrology depth and natal chart quality
Both apps calculate a proper Western natal chart from your birth date, time, and place. The math is not really where they differ. What differs is what happens after the chart is drawn.
Co-Star turns your chart into short, punchy interpretations and a stream of daily updates tied to current transits. The voice is opinionated and often funny, and that voice is the product. The chart is the raw material for the daily line.
Raka turns your chart into a conversation. You can ask the AI reading coach why your Saturn placement keeps showing up in hard weeks, or how a current transit is coloring a tarot spread you just pulled. It cross-references classical astrology with tarot symbolism and depth psychology.
For someone who already knows their big three and wants a witty reminder, Co-Star is enough. For someone who wants to actually understand their chart at the level of aspects, houses, and progressions, Raka goes further because it will keep answering follow-up questions instead of handing you one sentence and moving on.
Tone and voice: sass vs. reflection
Co-Star's voice is its identity. Short, blunt, sometimes brutal, occasionally hilarious. The push notifications are quotable enough that they end up in group chats and on social feeds. If you like being read for filth by your phone at 9 a.m., that is a real feature.
Raka's voice is deliberately different. It is grounded, reflective, and coach-like. It asks questions back. It is more likely to say, gently, that a card is pointing at something you have been avoiding than to hand you a one-liner about it. That is by design.
Which tone is better depends entirely on what you want from a spiritual app. Sass is great when you want to feel seen quickly. Reflection is better when you want to sit with something for longer than the time it takes to screenshot it.
Neither voice is wrong. But they attract different users. A lot of former Co-Star users end up wanting more depth once the novelty of the sass wears off, and that is often when Raka becomes interesting.
AI conversation: snippets vs. dialogue
Co-Star uses generation for its interpretations, but the interaction model is essentially one-way. You open the app, you read what it says, you close the app. There is limited room to push back, ask follow-ups, or steer the conversation toward what you actually want to talk about.
Raka is built around dialogue. The Mastery tier gives you unlimited chat with an AI reading coach that remembers your chart, your recent readings, and the context you have shared. You can pull a card, ask what it means for your current transit, then ask what practice might help, all in one thread.
This is the difference between reading a horoscope and having a mentor. The horoscope tells you what today is. The mentor helps you figure out what to do about it. Both have their place, but they are not the same product.
If your bar for AI is that it should hold a coherent conversation and remember you across sessions, Raka clears it and Co-Star does not really try. If your bar is that it should say one funny thing and go away, Co-Star is more efficient.
Learning and long-term use
Raka's 90-lesson course is one of the most underrated parts of the app. It is structured like a real curriculum, moving from basic card meanings through spreads, then into astrology fundamentals, then into how the two systems speak to each other. It is the difference between owning a deck and knowing how to read one.
Co-Star teaches by osmosis. You pick up terms — Venus retrograde, Saturn return, moon square Pluto — from the daily copy. That works for some people, and it produced an entire generation of casual astrology fluency, but it is not the same as sitting down with lessons.
This matters for long-term retention. Apps that only give you daily fortune-cookie content eventually get boring because there is nowhere left to go. Apps that teach you something get more useful the longer you use them, because your questions get sharper.
If you can see yourself still opening this app in 2028, the learning path matters. Raka is designed for that arc. Co-Star is designed to be delightful right now, which is a legitimate but different design goal.
Community, friends, and social features
This is the area where Co-Star clearly wins. Adding friends, comparing charts, and seeing your compatibility with the people you actually know is a real feature and a real reason to open the app. It turned astrology into something you do with your group chat, not something you do alone.
Raka has no social graph. It is a private tool. You cannot add friends, you cannot see anyone else's readings, and nobody sees yours. That is a deliberate choice tied to the reflection-first positioning, but it is a genuine trade-off.
If a big part of what you want is comparing your chart with a new date, a coworker, or your best friend, Co-Star does that natively and Raka does not. This is one of the few places in this comparison where the answer is unambiguous.
On the other hand, if the social layer is exactly what you want to escape — if you want a private space to work with your own patterns without performing them — Raka's silence on this feature is the point, not a bug.
Privacy and data posture
Raka positions itself as a reflection tool and treats your chart, journal notes, and reading history accordingly. Personal chart data lives on-device where possible, and the app does not need a social graph, so there is nothing to broadcast even by accident.
Co-Star's model is different by necessity. To power friend compatibility, it needs a cloud profile tied to other users. That is not sinister, it is just how any social feature works. It does mean that your chart and some behavioral data live server-side.
Neither app is uniquely careless, and both let you delete your account. But if you are the kind of user who reads privacy pages before installing anything, the shapes of the two products are meaningfully different. One is a private notebook; one is a small social network.
For sensitive material — tarot spreads about relationships, work anxiety, or grief — a lot of users prefer that the app not know their friend list. Raka's design choice makes that a default rather than a setting you have to hunt for.
Who should choose Raka, who should choose Co-Star
Choose Co-Star if you want a daily witty forecast, if you love the specific voice, and if the friend-compatibility feature is a real part of the fun. It is a well-made app that knows exactly what it is, and if that is what you want, nothing else quite scratches the same itch.
Choose Raka if you want tarot, if you want an AI that actually converses, if you want to learn the systems instead of just consuming daily lines, and if you want a private space rather than a social one. It is the better fit for people building a long-term reflection practice.
Both apps can also coexist. Plenty of users keep Co-Star for the morning line and open Raka when something bigger comes up — a decision to talk through, a card to sit with, a natal placement to actually understand. They are not really competitors on your home screen.
If budget is the deciding factor and you cannot justify $9.99 a month, start with Co-Star free and Raka free, use both for two weeks, and see which one you open without a notification prompting you. That is the honest test.
Honest limitations of both apps
Raka is new. It launched in 2026, and while the tarot course and AI coach are strong, it does not yet have the years of copy library and cultural gravity that Co-Star has accumulated. Some people will bounce off it simply because it does not have the same recognition.
Raka also does not have a social layer, human astrologer chats, or a friend graph. If those matter to you, that is a real gap. Nothing about the roadmap suggests a pivot toward social — the app is intentionally private — so this is unlikely to change.
Co-Star's limitations are the mirror image. There is no tarot, no long-form AI conversation, no structured learning path. The daily voice, while iconic, can also feel repetitive after a year or two, and some users age out of the tone as their questions get more serious.
Both apps are self-reflection tools, not fortune-telling engines, and neither replaces therapy, medical advice, or a real conversation with a trusted person. Use them as prompts for thinking, not as instructions for living.
Final take
Raka is the better app if you want depth: tarot, a real curriculum, an AI you can actually talk to, and a private space to build a practice over months and years. It is priced like a small course because it functions like one.
Co-Star is the better app if you want personality and social: a sharp daily voice, friend compatibility, and a low-friction way to make astrology part of your group chat. It is free to start, and for a lot of casual users that is genuinely enough.
The two apps are not really rivals. They are answers to two different questions about what a spiritual app should do in 2026 — entertain you daily, or help you understand yourself over time.
Pick the one whose job matches yours. If you still cannot decide after reading this, install both on the free tier, use them for a week each, and notice which one you open without being pinged. That is the answer.
