### 3/5 — unreliable for me

*2026-01-12*

freezes almost every time I use it and the settings, including the IP address are not not saved requiring input each time the app is opened.

### 5/5 — Great app

*2025-10-14*

This is a good app because it is a portable application that allows you to sit inside and watch your Astro image reveal its self from the darkness

### 4/5 — Look great. Waiting for more features.

*2025-08-02*

Missing a few things. Doesn't show how many images have been taken out of the sequence or progress. Doesn't show the HFR data.
