I haven't downloaded it, I'm just going by the screenshot so if I'm wrong then apologies.

The big criticism I've had of most software for a long time is that it doesn't make cave diving profiles easy. They all assume a straight descent at a constant rate. Not many allow you to, for example, enter a start depth, an end depth and specify how long it is going to take you to do that. Most rely on a preset descent rate that gets used for all depth changes which is really restrictive on cave planning.
