### 5/5 — 10/10

Crucial astronomy app, 1 of my go to 3

### 5/5 — Genuinely an amazing app

*2026-05-24*

This app is incredible. Is accurate and has so much information. I am unsure how I would properly function without this. From Aurora forecasts, seeing, clouds, transparency, astronomical calendars, and so much more the app is a MUST for any astronomer or those aspiring.

Thank you!!!

### 3/5 — Just not accurate

*2026-05-18*

Love the interface but the forecast for me is not accurate. Shows no clouds (dark blue) when there is 109% cloud cover. East of England.

### 1/5 — Used To Be Great

*2026-05-08, version 14.8.4*

The app used to be great.. then it just stopped working.  Even after updating it fails to give a forecast.  Just a notice saying “network error”.  Too bad.. I used the app frequently for about two years.  Now it’s useless

### 5/5 — Precision tool that helps determine when to shoot

*2026-02-22*

I LOVE this app.  It’s been a godsend for astrophotography and helping identify good seeing for my location.  That is very beneficial when determining if I want to shoot in Ha, for better detail, or if Oiii is the play tonight since the seeing is a bit worse.  The accuracy astonishes me… why can’t all weather reports get this precise!  Really one of the best values I’ve found.

### 5/5 — Love it!

*2026-02-20, version 14.5.3*

Everything I need in one place, works very well and usually almost spot on, prob more accurate than our local TV weatherman, ha ha!

### 5/5 — Best app for astrophotogrpahy

*2026-02-10, version 14.0.4*

This app is the most accurate I’ve used yet. Worth every penny.

### 1/5 — Stopped Workong

*2025-11-15, version 12.6.11*

I’ve had this app for some time now. And on my iPhone iOS 18.7.2 it stopped working a few weeks back.  The main page keeps reloading, no matter where I’m at in the app. It’s essentially useless now.  And I can’t find any way to contact the developer for support..  I will really miss this app, and will be hard pressed to find a replacement.  But I don’t seem to have any other option as this point.
