Every morning, five days a week, we publish iPhone how-tos to help you get the most out of your phone. But just as important as understanding how your Apple devices work is finding the best apps to use with them. That's why every Saturday we share one of the apps the iPhone Life Team has used and loved with our readers. According to AARP, only four out of ten American adults have created a will. Writing a will is an important step for every adult, particularly for those of us with children, because we don't want those we've left behind unprotected and confused about our final wishes. Since I'm one of the six out of ten who haven't made a will yet and don't want to spend the time and money to visit a lawyer, I've made it my mission to find a way to write a do-it-yourself online will, preferably for free. I've found an iPhone and iPad app called Tomorrow that not only helps users write a will, including designating heirs, executors, and guardians for children and pets, but also walks us through the process of purchasing life insurance and setting up a trust for our beneficiaries. To learn more about how the Tomorrow last will and testament app works, read on.
