Comparison
Täherada vs Co-Star - which astrology app is better in 2026?
An honest comparison of Täherada and Co-Star astrology apps - features, pricing, languages, AI, privacy. Helps you pick the right one.
If you are looking for a solid astrology app, sooner or later you will bump into Co-Star - the New York-born horoscope app that went viral in 2020 thanks to its blunt, dark-humoured voice. Täherada is a later-generation app built in Estonia, available in 15 languages, powered by live cosmic data, and giving you a personal AI companion. This guide answers honestly which one would suit you better - we are not here to trash Co-Star, we are here to explain the differences.
At a glance
What Co-Star does well
Co-Star did one thing better than any other app before it: it made astrology cool. Dark minimalist design, blunt push notifications ("today you leave on time"), and a "friendly roast" voice worked perfectly with meme culture and Twitter/X. Co-Star quickly became the go-to app for millions of Gen-Z users in the US.
Co-Stars second strength is the "Friends" feature, showing astrology compatibility between you and your friends. It is social, fun, and pulled in a lot of new users. Co-Stars birth chart is also visually gorgeous - it is known for the bold white text on a dark background aesthetic.
Where Täherada wins
First - language. Co-Star is English-only. If you are an Estonian, Finnish, Swedish, Lithuanian, Ukrainian, Russian, or other non-English speaker, you either use Co-Star poorly ("I miss the point of half the pushes") or switch apps. Täherada is built from day one in 15 languages including Baltic and Nordic ones that big US apps usually ignore.
Second - AI conversation. Co-Star sends you static pushes. Täherada lets you chat with a real AI astrologer (powered by GPT-5) who knows your birth chart and answers your specific questions. "Why cant I get along with my partner" gets you a personal answer on Täherada; Co-Star would send you an 80-character push instead.
Third - privacy. In 2020 Co-Star reported a data breach where user birth dates and coordinates were exposed. Täherada is a GDPR-compliant EU service. You can export or delete your data at any time - it is built in, not added on later.
Fourth - live cosmic data. Täherada integrates NASA (APOD, planetary data) and NOAA (solar storms, Kp-index, aurora activity). When you read your horoscope you see actual astronomical context - not just a birth chart calculation.
Where Co-Star might fit better
If you are an English-speaking US user who enjoys meme culture and short, dryly funny push notifications, Co-Star will probably fit you better. You do not even need AI to replicate that tone - Co-Star is the master of its own voice.
If you do not enjoy chatting with AI ("I do not want to talk to the astrologer, I just want a little notification") and prefer an app that decides when to send things for you, Co-Stars automatic push model will probably feel comfortable. Täherada makes chat an option, not a requirement.
Price comparison
Co-Star Plus costs $7.99 per month and unlocks extended horoscopes and more friends. Täherada Premium costs €4.99 per month (or €49/year, which is ~€4.12/mo) and unlocks unlimited AI chat, a personal annual forecast, synastry deep analysis, ancestral chart, and every gated feature.
In euro terms Täherada is now noticeably cheaper (€4.99 vs ~€7.30) and offers significantly more features. The most important is the AI chat - if you use even one AI chat per month, Täherada Premium pays for itself.
Verdict
If you are not a native English speaker, want truly personal answers, and value EU-based privacy - pick Täherada. If you enjoy Co-Stars meme-like voice and a steady drip of push notifications is enough - stay with Co-Star. Both are good products; they solve different problems.
Frequently asked questions
Does Täherada use the same astronomy data as Co-Star?+
Yes - both use Swiss Ephemeris, the industry-standard ephemeris. The difference is in interpretation and presentation, not in the underlying numbers.
Can I import my Co-Star birth chart into Täherada?+
Not directly, but you just re-enter your birth date, time and place - the same three data points you gave Co-Star. The resulting chart is identical.
Which app is better for an Estonian-language user?+
Täherada is built in Estonia with full Estonian content - horoscope, AI chat, push notifications, emails. Co-Star is English only, so for Estonian users Täherada is the much better choice.
Is the Täherada AI chat free?+
You get one free question per day. Additional access costs €1.49 (1 question), €2.99 (3), or €4.99 (6), or unlimited with Premium. Co-Star does not have an AI chat at all.
Does Täherada support Android and iOS?+
Täherada is a progressive web app (PWA) - it runs on all devices (iOS, Android, Windows, Mac) directly in the browser. You can add it to your home screen like a native app, without going through the App Store.
