5 of 5 iPolar May 1, 2024
Reviewer: Bob  
I have an HEM15 with a built-in iPolar.  I also have a QHY Polemaster.  The Polemaster does not do plate solving.  It uses the RA rotation method.  I found the alignment procedure for the iOptron to be very quick and easy compare to the Polemaster.  I am using a laptop, so I can't comment on phone apps.  I would like to see an upgraded connector.  The mini-B is close to obsolete.

On another note (to iOptron), we know most phones and Ipads have USB ports.  Maybe a modified windows software using a USB cable direct?

1 of 5 Its 2024, Still no good software March 24, 2024
Reviewer: RKumar from sunnyvale, CA United States  
I brought it back in 2020, For 3 years they have been saying they are making software for Mac, iOS, and Android. But all we have is bugging Mac software which keeps crashing and stops working with every update. For Windows, we have to invest another minimum 400$.

To all future users, please stay away from this stupid and expensive hardware, it is of no use without software. Till their sale take a hit, they are not going to improve.

4 of 5 Needs polar alignment app for Android October 16, 2023
Reviewer: Anonymous Person from United States  
Please make an Android app that is the functional equivalent of the Windows alignment software allowing USB OTG connection. There is an existing Android app called USB Camera ( that is able to connect to and control iPolar via USB OTG as a web cam.

2 of 5 ioptron erratic quality on mounts and ipolar scope September 19, 2023
Reviewer: albert poncedeleon from carbondale, IL United States  
I have three ioptron mounts. All suffer from one problem or another. High error in tracking, more than stated in their website. Ipotron polar copes fail to make contact with the cable and the female connector in the polar scope gets loose and fails to make contact. They do not have support for these ipolars and nothing for the bad PEC of the mounts. Expensive and mediocre quality.

1 of 5 Cem26 w/ ipolar December 31, 2021
Reviewer: Oriol Quirant Banus from Vilamaniscle, Girona Spain  
Do you spend $ 1400 on a mount with Ipolar, or $ 2XX and you have to pay $ 10 more for the App in the Mac App Store? Seriously Ioptron? Is this all the support you offer to your clients?
What a shame.
And you don't have an App for Android / IOS?
Then you go on saying that you have the latest technology.
The next HandControl will be a caveman stick.
