Love it!

So easy. Love it!

Used it for many years. Great App

I love this app. I use it every day. It’s a shame that the alarm feature stopped working a few years ago. But since sidereal time only changes four-minutes a day, it’s easy to kind of remember. I would happily pay the $4.99 again to get the alarms working.

Alarm Doesn’t Work

First off, this app is a great idea. I love the ability to track and plan around optimum sidereal times. I just wish the alarm feature would work. I wake up to find the notification in there on my screen, but no noise or notification to my watch, even though I’ve allowed them to come through my sleep focus settings.

Also, it would be great if the β€œContact Us” function didn’t require me to setup the canned email client on my iPhone in order to email the developer. I don’t want to do that and since there was no way to get the email address that I could find, I’m forced to leave a review in the hope that the developer reads my concerns here.

It might sound like I’m unhappy with this app. Far from it. These are just areas of improvement I see. Thank you!

Gotta have this app , so modern

Remember the old days, before the internet, before cell phones, when time was synchronized with the WWV radio. And sidereal time was calculated with your HP calculator? The one with RPN (Reverse Polish Notation). Gone with the wind. Now it’s easier than falling off a log.

Pro Purchase problems

Purchased pro version. Had to reset phone. App has an option to restore pro purchase I’d already paid if the app needs to be reinstalled on a device. It did not work.

FAQ

What is local sidereal time and how is it used?

Local sidereal time is a timekeeping system used by astronomers to accurately locate celestial objects in the night sky. It is based on Earth's rotation relative to the fixed stars or the March equinox, allowing for precise pointing of telescopes.

What are the benefits of using this app for personal development?

Studies suggest that certain local sidereal times, specifically around 13:30 LST, may increase psychic abilities and remote viewing skills by up to 400%. The app can help users track these times for meditation or personal exploration.

What features are available in the pro version?

The pro version offers advanced functionalities such as receiving notifications for specific sidereal times (e.g., 13:30 LST), planning future meditations by accessing upcoming 13:30 LST times, calculating sidereal time by address, latitude, and longitude, and converting current dates and times to sidereal time. It also allows users to touch anywhere on a world map to find the local sidereal time.

Is this app compatible with my device?

While the description does not specify exact compatibility, this app is designed for mobile devices. Users should check their device's app store for specific operating system requirements (e.g., iOS or Android versions).

How can I find the local sidereal time for a specific location?

The app calculates local sidereal time based on your current location. With the pro version, you can also calculate sidereal time by entering an address, latitude, and longitude, or by touching any point on an interactive world map.
