Looking for a Co-Star alternative: what are you really after?
People rarely leave an astrology app because it is bad. They leave because they have exhausted what it can do: the morning notification is fun, then it starts repeating itself. So the useful question is not which app is best, but what you want to read.
Two different products, often confused
Daily horoscope apps — Co-Star being the best known — are built for short, regular use: a line in the morning, a compatibility score with a friend, a carefully designed aesthetic. The format is deliberately brief and very well executed. A written analysis answers a different need: understanding a whole configuration, with its nuances, its tensions and what connects them. Blaming the first for being short is like blaming a text message for not being a letter.
The signal that it is time to move on
Three symptoms keep coming back. You reread the same notification without knowing where it came from. You want to ask a follow-up — why? what about work? — and there is nobody to ask. And you start noticing the message could apply to anyone. All three say the same thing: you now want a reading attached to your chart, not a message of the day.
What Spikka offers instead
Your chart is computed for free, with the Ascendant, the houses and the aspects. From there you can question an assistant that works on that specific chart rather than on your sun sign, and order written analyses — natal chart, forecasts, synastry — whenever you want to go deep on one subject. In English and in French, on the web, with nothing to install.

A comparison of categories, made in August 2026 from public information. Co-Star is a trademark of Co-Star Astrology Society and is not affiliated with Spikka; app features change, so check the current state before deciding. The two formats also complement each other well: nothing stops you keeping a daily app and reading a deeper analysis elsewhere.
Frequently asked questions
Is Spikka an app I have to install?
No, it is a web space: it opens in your phone or desktop browser, with no installation and no updates. You can add it to your home screen if you prefer one-tap access.
Is there a daily horoscope?
Not as a morning notification. Your space shows the day's sky mapped onto your own chart, which is a different kind of information — and you can ask the assistant what a given transit means for you.
Is the calculation the same as in other apps?
Planetary positions come from ephemerides: computed properly, they are identical everywhere. What really separates two tools is the care taken with time zone and place, the house system, and above all the quality of the interpretation.
Can I try without paying?
Yes. Creating your space and computing your chart are free with no card required, and a few chat messages are included so you can test the assistant. Written analyses are then bought individually, with no forced subscription.
Can I compare my chart with someone else's?
Yes, in two ways: a shared chemistry reading, where the other person enters their own birth details from an invitation, and a full synastry report if you want the detail of the aspects between both charts.
Is my data used for anything else?
No. Your birth data is used to compute your chart and produce your analyses. Hosting is European — Frankfurt for both the app and the database — and the privacy policy details retention periods and your rights.
