What's New in Solar System Clock

1.8.1

September 17, 2026

New in Version 1.8.1: - Siri now has access to the Solar Clock times on every planet and every moon when the full version is purchased. Siri responds to requests involving the words "Solar Clock time." Fixes in Version 1.8.1: - Fixes a crash where setting the calendar view to year zero would cause a division by zero error. This affected iOS 27, where the code to ensure zero was never entered as a year was no longer functional on some devices. We sincerely apologise for this error, and we would like to reassure our users that bugs will always be fixed as soon as we are notified of the issue.
