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.
Should add drop in feature
My location is a slightly different from the location shown in the app. It would be nice if you could add drop pin feature
Remote viewing??
Useful for astronomy and astrophysics but the app seems to promote pseudoscientific "remote viewing" experiments? Not sure how to feel about that
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.
Didn’t work
Kept crashing while trying to load
How often do I have to pay $4.99???
Every time I want to use the app, I am prompted whether to buy the Pro Version or not. I hope you do not mean to insinuate your clients need to pay for every time they are inclined to use your sidereal app. But, even after I paid the $4.99, I still could access the LST I wanted. I paid for no service at all. Talk about a rip off!!!
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 “Contact 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.
What do you get with a purchase of this app?
I’m trying to figure out what this app does? It’s unclear in the notes and quite honestly I think that you could price this app at a more affordable price with a better description of the advantages of 13:30 time. Just saying.
Excellent tool, good support!
I am really happy with the $4.99 upgrade to pro. Nice app - thank you!
No alarm sound for the notification
Even when turning on the sounds in the notification setting There’s no alarm or tone it just pop at the screen
Useful
Meets my needs.
1 star
One of the most annoying things developers do is program a pop up to incessantly ask you to write a review while you are trying out an app. Canceling the request on this app ensures it will pop up again in a minute or two. I have no idea how well this app works because it won’t leave me one until I review it. And this is after I paid for the upgrade to get local times. Hope this helps.
Notification’s
You can’t clear old notifications unless you completely turn them off what a pain
Wonder about the accuracy and security of this app.
For weeks now there’s a bug that causing a red flag which hasn’t been fixed yet. They don’t seem bothered to quickly fix it. Considering I am using a paid version, I would say it’s a total waste of money.
Thanks for the reminder!
Great app! Pretty simple and straightforward. I have the app set to send me a notification 15 before 13:30 sidereal time everyday. Both the wife and I have had awesome experiences when meditating during 13:30 LST. 🙏🏼
I
I am buy this application but every time ( try a gain )
Notification
It says I have a notification but I can’t find it, other words I don’t have any notifications from the app that I can see just the number 1 at the app
الاطبيق لا يعمل
التطبيق لا يفتح لا نستطيع استخدامه
Alarm feature
This is an amazing app. I will suggest a feature to place an alarm (not just a notification) about an hour or half hour before 13:30 hour or any time
Saudi Arabia /Riyadh
The App can not define my location
Question about DST
Since the current (spring/summer) clock time in most of the US is fake daylight savings time, do we need to add an hour to the app’s stated local sidereal time when we are in fake DST? Then use the stated LST time as true sidereal time when we are returned to standard time in fall/winter? The app doesn’t automatically correct for daylight savings time according to our individual location?
Takes forever to load.
Takes forever to load. No extra features. Get another LST APP
Yes !
I love the pop up reminders. Also the informative articles about ST. Thank you. Could you leave the pop ups on longer. They are easy to miss if you look away.
A Very Strange App...
...it just opens on a screen that says “Getting Time” but it never seems to manage it. Most menu options says that it’s necessary to purchase the Pro Version - for which there is a helpful button. The explanatory notes provided by the author hint that his knowledge of astronomy is poor but he does seem to think that Sidereal Time has some sort of effect on the user’s psychic powers... very strange. In summary, an App to be avoided.
