Thanks, for the file, Aled! I've added it to the Freediving Media Base, to the software section:
software @ APNEA.cz
There are already eight static apnea tables applications. You can also check the one at
APNEA.cz - Apnea Training Manager - it goes little bit beyond the usual ones - it offers not only static tables, but also more complex exercises, full training sessions, or even courses or yearly training plans, dynamic, depth, and theory sessions, logging, statistics (still in development), team management, and much more.
