### 5/5 — Much gratitude to the developers

*2023-12-07*

This is a perfect little app, I use it everyday. I send my thanks to whoever took the time to make this. Mahalo

### 4/5 — Ok for a quick look

*2022-10-31*

I’ve been using this app for a long time just to check basic info.  I’d like to be able to zoom in.  Not optimal for visually impaired. The background color doesn’t work with the colors of planets/signs.  Should be more contrast.  Like black background with bright colors.  I have a terrible time with that.  I never expected this app to be professional since it’s free.  So I’m okay with it except for the notes above.

### 1/5 — WYSIWYG

*2019-07-21*

If you don’t understand the screenshots in the App Store, do not download this application.  It does not provide any information about how to interpret the data which is displayed.  

I was looking for a tool to tell me where the sun would appear in the sky on various days of the year.  Aside from the fact that the app only supplies real time data, I have no idea how this relates to the position of the planets in the sky.

### 3/5 — VOC not accurate

*2017-11-29*

Just updated this app and although they fixed the aspects (that weren’t an option) the VOC is still wrong. Would like to see an aspect feature

### 5/5 — Excellent

*2017-11-09*

I love this app for its simplicity 🌎🌞🌛
I carry my birth chart details around in my head so I don’t need anything more than an uncomplicated list of planetary positions to check my transits any time anywhere. 
Many thanks to the developers for keeping the app updated, I couldn’t be without it❣️

### 5/5 — Perfect app

*2012-10-17, version 1.6*

Quick, easy, useful. Use it everyday. Thanks dev.

### 4/5 — A handy tool

*2012-03-13*

I would like more options for configuring the app. Please fix the void of course function -- even your sample image shows moon void even after entering the next sign. It gets stuck in void a lot. 
The app is pretty cool tho.

**Developer response:** Please try our new version 2.0 and let us know if the void of course issue is now resolved.  Thank-you!

### 1/5 — of very limited use

*2011-03-21, version 1.6*

This app does not allow for local time, nor does it allow you to view other dates and times and actually use it as an ephereris.  You can type in your latitude and longitude, but it has no effect on the readings you get - so what's up with that?
I think that $1.99 for an ephemeris that does not allow you to look at anything but this exact moment (and not even at your locale, but heaven only knows where) is not worth the price.

### 3/5 — No Aspects

*2011-01-15*

Disappointed that there are no aspects even though there is supposedly an aspect selection.  I want to know who is conjunct, opposition, retrograde, etc.  Just knowing what signs the planets are in isn't enough.  I would not buy again but keep looking.

### 2/5 — Poor Customer Support, would like my $ back, please.

*2010-10-11*

I was very disappointed in the customer support regarding the moon void-of-course for this application.  For some signs it is always void and other signs it is never void.  All I received from the developer is an explanation on when the moon is void and I am already well aware of that.  The developer did not respond to my next email.  This is a mediocre application with no customer support.  I would love to have my $ back.
