The app is for the #eVscope telescope and works great! The screen view is just like the scope view. Looking forward to maybe being able to adjust exposure and gain in enhanced mode in the future. Right now you can't. The scope goto and tracking works perfectly. This is a fine all in one telescope which takes about 5 minutes to set up and start using. It is the future and I look forward to it getting better and less expensive as time goes on!

The app is intuitive, simple and easy to navigate. However it was laggin in making WIFI connection. The wifi connection drop unexpectively a few times during one observation. APP info was not clearly indicate that it needs a GPS/Celluar model. Tablet with A-GPS, GLONASS is not compatible with the app. The storage is not cleared after images was uploaded. This issue was reported to tech support a few days ago, but still no respons from tech support. Tech Sup was slow in respond.

Hello Jean, we apologize for any inconvenience caused, however, many people use tablets with no GPS you just need to correct your settings appropriately. It currently takes us up to 72h to get back to our customers (especially when they reach out on Fridays at 7 PM - our local time). Thank you in advance for your understanding.

Newest version 1.3 is superb. Works well on Apple and Android. Vastly improves on image quality at the eyepiece and final tablet images. Also many bugs are now non-existent. The eVscope is my favorite possession. Older info: App is excellent but they are working out a few intermittent bugs. The app seems to work far better on my ipad than my samsung galaxy s9. On my samsung, the target list takes a long time to load and sometimes I have to restart phone to get it to be the Operator (this is the controlling user of the scope). But even in the past month, 2 updates have added cool stuff and fixed some bugs. The eVscope itself is amazing. Do not believe the videos and haters out there. Check out Unistellar Facebook pg.
