Comments on SkyPortal for Android

★★★★★ Rick Collins · Sep 28, 2025

With the GPS module on my new electron NexStar 8SE, I can move the scope to any visible object with ease. Do a quick alignment and enjoy the night sky's.

★★★★★ The story Incident · Jun 1, 2026

For those who can't afford sky safari this app is the best, why because it was Wi-Fi and almost has the same features of sky safari while half of it, now because I have sky safari pro, it's a little useless, but I rated 5 stars so you all and electron won't get mad, also call me artan and forget my email

★★★★☆ Kimomo · Mar 27, 2025

The only reason it is not 5 stars is that the ap is not accurate according to my location. I even manually put in my current latitude and longitude coordinates and elevation, and my app is still slightly off. This is causing a discrepancy in my telescope alignment with the stars. I tried playing with it to reverse polar and other settings, and I even tried changing the time and still had the same issue. This is the only drawback to this app for me. Does anyone have any pointers or tips?

★☆☆☆☆ Brittany Thompson · Apr 7, 2026

I've been using this iPhone app for years and recently switched to an android, and I'm not sure if it's because of a new update, but it won't #connect to scope" which I've never heard of before, and I don't have the compass option that I've always used to move my camera around and see everything I'm pointing at. This is so disheartening.

★☆☆☆☆ Gage Salerno · Jan 10, 2026

This only works when connected directly to the Electron Wi-Fi module. This app will not allow you to send the Wi-Fi module your routers' internet SSID and password so when using the app you cannot connect to the internet.

★☆☆☆☆ Aaron Silverman · Jan 19, 2026

This app was 5-star great until a recent update. I've used it for years. Now, the compass is broken. If you try to use the live sky map or locate an object, the current location coordinates continuously change very rapidly, and the view is blank except for occasional brief flashes of lines. Hoping for a fix soon!
