STELLAR REVIEWS
“Absolutely love this. The colors are beautiful and I love knowing when the Full Moons and Retrogrades are happening.”
“This calendar is fantastic. I love being able to plan my work around big transits and retrogrades coming up. This calendar makes it really easy to do so. The art is stunning.”
“Love this calendar. I love that it's divided by zodiac signs and not by the months. It's a new, fun, astrological spin on time and space.”
“I *love* this calendar. A totally cool way to restructure the way we think about the passing of time, and as a budding astrology student it's awesome to have the planetary transits right there.”
“I love the concept of going by the zodiac calendar. A visually beautiful calendar and unique concept!”
Would be cool to have widgets that can give us a quick overview of any planetary goings-on. Would be nice to be able to skim the calendar itself and be able to see what changes are happening maybe with shorthand symbols. I think the ‘lunar phase’ app does this really well and I use their calendar on my Home Screen to see everything but it’s just the moon so it’s a bit easier. Maybe a way to search for the next specific planetary movement… like the next time Mars is in Scorpio or something. Would be helpful for planning events. Also… Please please please make it a possible one time purchase when it’s out of beta, I don’t care if it’s super expensive. I really like this app but don’t like subscriptions and it’s hard to justify for a calendar app.Maybe having conjuncts also as June 27 the moon conjuncts with Saturn
Developer Response
Thank you, and these are thoughtful ideas. A lot of them come back to making transits easier to take in at a glance, which is something I think about a lot. Conjunctions and other aspects in particular are on the roadmap, so those are coming in a future update. On pricing, I hear you on subscriptions, and keeping the app fair and accessible genuinely matters to me, so that's something I'm weighing carefully as it grows. Thanks for taking the time to provide all this genuinely helpful feedback.
So much better for following seasonal changes
Lina Vornovi
This app is amazing. I’m not an astrology person, but I grew up with it and so I just wanted a calendar aligned with solstice / equinox dates better. I moved to a cold city from a tropical climate and adjusting is hard. This format follows seasonal changes way more accurately and I feel more connected to nature and the passage of time, it’s helped me adapt. I got the calendar on Etsy too because I appreciate and support that this is free.
Developer Response
Thank you, this is wonderful to read. Aligning the calendar to the solstices and equinoxes is exactly what it's for, and it's especially meaningful that it's helped you feel more connected to the seasons while settling into a new climate. That sense of moving with nature instead of against it is the heart of the whole thing.Thank you also for picking up the print calendar on Etsy, and for the kind words. Wishing you an easy adjustment to your new home.
Great Zodiac Calendar App!
NoirAlice
I love how simple and elegant this app is and keeps you up-to-date on the latest celestial events. It seems so many apps are going to the subscription service, so I appreciate that this is free. Thank you so much! I would love for this app to include the sidereal calendar, as that is my preferred method of interpreting the skies. My only suggestion! 👍
Developer Response
Thank you, keeping it clean and easy to use while still holding all the deeper detail and nuance is exactly what I aim for, so it means a lot that it comes through. A sidereal option is on the roadmap, so stay tuned, you'll be able to read the skies your preferred way in a future update.
Just what I was looking for!
Nizhoni_e
The only thing missing is the ability to integrate the calendar directly into iCal for all devices instead of just viewing everything in app. (also a possibility that I haven’t figured out how to do that on my own lol) Beautifully done!
Developer Response
Thank you, so glad it's been what you were looking for. You haven't missed a setting, that part isn't possible yet: right now the app brings your calendars in to view alongside the astrological events, rather than sending its own events out to iCal across your devices. Letting those sync out to your other devices is on the roadmap though, so stay tuned for it in a future update.
