I'm considering the BlackbeardX and have read great things about the hardware, but the software seems to be the weak point. Reading through the reviews of the software in Apple's app store, there are comments referring to the app crashing, "plagued with problems", etc. However, most of the reviews are years old. Has there been improvement in the stability of the app? Overall the app gets a 4.4 out of 5 stars, not bad, but I'm looking at dropping $320 for the hardware, so I'd like to be confident in the overall benefits of the entire system, not just the hardware. One other question please; what is the difference between the basic Mantis X app and the Laser Academy? Is the Laser Academy required for use with the BlackbeardX? Thank you for any input.
