Review summary

OnStep Controller2 is praised for its rich features, easy setup, and stable integration with telescope hardware, especially replacing older hand controllers and enhancing user experience. Users appreciate its open-source nature and continuous development. However, multiple users report frequent app unresponsiveness and freezes, impacting usability. A few features such as accurate UTC offset handling, PEC index indicator, and enhanced focus controls are missing or need improvements.

Pros

Easy setup and connection.
Rich features making it a complete and easy to use telescope control app.
Effective replacement for traditional hand controllers and other control methods, especially with Bluetooth integration.
Stable operation with OnStepX and useful for observations without a PC.
Open-source project with strong community appreciation and continuous improvements.

Cons

App frequently becomes unresponsive or freezes, causing pop-up errors every few seconds.
UTC offset settings are inaccurate, requiring a manual hour adjustment.
Missing some features like PEC index indicator and polar hour angle calculator for better debugging and alignment.
Lack of certain controls like a slide bar for focus adjustment instead of just buttons.

2024-05-19	Fl*****	Pixel 6 pro, android 14, FYSETC E4, the app is not responding So on the plus side, setting the app and connection up was very easy. On the downside I get a 'the app is not responding' pop-up every 5-10 seconds. If there is anything I can do to help troubleshoot I'd be glad to be of service.

2023-08-31	BM*****	Good app. Just found a small bug. The UTC offset needs 1 extra hour to be added. For example +5:30 (India) needs to be set as +6:30 else it becomes 1hr more !
