There are 2 ways you can extend a helping hand:
One is by donating to Red Cross through iTunes. With your iTunes account, the process is quick and easy. According to 9to5Mac, "Apple has responded in the same way to a number of previous disasters, including Typhoon Haiyan in the Philippines, the earthquake and tsunami in Japan, the earthquake in Haiti and, of course, Hurricane Sandy. Apple also invited donations for cancer research organization City of Hope in 2014."
And two, another easy and convenient way to help, which John Gruber of Daring Fireball has linked to, is UNICEF's relief efforts through Square.
No doubt, humanity's finest hour is when people from all over the world come together, setting differences aside, to extend a helping hand to those whose needs are truly dire..
