The UNICEF Experience app for Android and Apple devices allows you to make contributions to the United Nations fund that buys items for aid work around the world. You could pay $1,933.51 for an emergency tent, for example, or $32.35 for a first aid kit. The app uses the PayPal payment system to complete your donation. If you need to set up a PayPal account, you can do so on the PayPal app.
You can also use PayPal to donate to the Philippine Red Cross. See how to do so at the Philippine Red Cross website, www.redcross.org.ph.
World Vision Now, from the faith-based World Vision relief group, is a free app for Apple devices that has a "Donate Now" button accompanying reports on the devastation in the Philippines. The button links to a Web page where you can tap to choose to donate suggested amounts up to $150, or fill in a blank for any amount.
Hurricane by American Red Cross, free for Android and Apple, has functions for preparing for a hurricane, getting alerts, and tracking storms. But there's also a button for making $10 Red Cross donations via text.
The hurricane app also includes a link to a second app, Team Red Cross, that you would use to sign up as a Red Cross volunteer in your home area. Assignments, according to the app, may include "disaster assessment, feeding, bulk distribution."
