Made for the eyepiece
A planetary almanac you can see.
The Wanderers' Almanac is not a general-purpose planetarium with the planets buried in a menu. It is a compact visual companion for observers who want to know what a planet and its moons are doing now—or at a time they plan to observe.
Move backward or forward in time, swipe between planets, label the major moons, and mirror the view to match your telescope. Open the ephemeris when you need the numbers behind the picture.

Frequently asked questions.

Which devices are supported?
The Wanderers' Almanac requires iOS 17.6 or later. Available for both iPhone and iPad.
Is there an Android version?
An Android version is planned, but it is not available yet. No release date has been announced.
Does the app need an internet connection?
No. The astronomical calculations and bundled ephemeris data run on the device, so the app remains useful at observing sites without a network connection.
Why does the app ask for my location?
Your observing location is used on the device to calculate rise, transit, and set times along with altitude and azimuth. Starstone does not collect or transmit your location or other app data.
What do the moon-label colors mean?
White indicates a normal moon position, red indicates a shadow-transit state, and yellow indicates an occultation state. You can turn moon labels off in Settings.
How accurate are Great Red Spot transit predictions?
Jupiter's Great Red Spot is a dynamic weather phenomenon, and its observed position drifts over time. Transit predictions may therefore vary by a few minutes from other sources. The Wanderers' Almanac will be updated regularly with the latest observed position so its future predictions remain as accurate as possible.
How do I match the view in my telescope?
Use the vertical and horizontal mirror buttons at the upper left of the planet view. These controls help match the display to different telescope, diagonal, and optical configurations.
How do I return to the current time?
Double-tap the date and time shown near the bottom of the main screen. The time slider will return to now and resume following the current time.
Are there ads, subscriptions, or tracking?
No. The Wanderers' Almanac is a paid app with no ads or subscription, and Starstone collects no data from the app. See the privacy statement for details.
Can my family share the purchase?
Yes. The App Store listing supports Apple's Family Sharing for up to six family members when Family Sharing is enabled.
