Not sure if possible in free app (you can try) but I've been using paid version which after latest update allows to change fps and surprisingly I can set 240 fps (although it looks like 120 fps with doubling of the frames to reach 240).
Video looks super smooth and crisp when played at 25% speed.
No luck with higher resolutions, only 30 fps available
Thanks for your post, I downloaded Ultracorder as well and made a video comparision between slow motion modes which I uploaded on Youtube and I´m not allowed to post because I have <10posts.
The internal slow motion camera always records on 720p 240fps with no options of changing the framerate, but you can choose the normal and wide angle lens. The wide angle lens footage looks worse than normal lens though.
In the Ultracorder App you can also choose 1080p with 120fps with the normal lens. It works fine and enhances the quality a little bit.
You can also choose 1080p 240fps but if you record with that setting, you get a file with 160fps and dropped frames. I thought maybe the memory write speed was too low, so I also tried recording it on my Sandisk Extreme MicroSD with the same result of 160fps.
In Ultracorder you can max. choose 30fps with the wide angle lens.
