This is a fairly basic SSH app. The pro version offers only a few small extras over the free version, so I suggest to check that one out first before you get the Pro version. I feel like there are some UX improvements to be made here. Some of the buttons are extremely hard to hit because the hit boxes are too small. Also every SSH session opens inside a sort of popup instead of full screen. While a lot of commonly known themes are available, it doesn’t look like they have much impact. For example the background color is always the same. Customization in general could be improved. There is also no option to change the font face.
