How far into the developmental aspects would this program get someone? Say I wanted to participate in M.A.D could I obtain that skill even on a mediocre level?
how far you go doesnt depend on the app, it depends on the time, effort and efficiency to which you learn. as for MAD, the only one im familiar with is the doctrine of Mutually Assured Destruction which id advice against for health reasons.
Mobile App Development.
and with all the time, effort and efficiency in the world there is still a cap on how much you can learn solely within this app, (i assume).
