There's pretty much an app for everything nowadays and the Philippine Red Cross is no different with their Hazards App. The following are the salient features of the app:
1. "How to" guide and tips on how to prepare for and respond to various calamities such as fire, tsunami, floods, etc. You can even test your readiness by choosing "Test yourself."
2. Allows you to monitor up to 5 locations for any disasters. Upon first opening the app it will ask what town you live in and that will be the first location monitored. You can add 4 other locations for monitoring as necessary.
3. Allows you to report an ongoing hazard and mark it on the map. This is a pretty useful crowdsourcing tool especially if you're travelling during inclement weather and need updates on the route you're taking.
The last two features require an Internet connection, but with the wide availability of both postpaid and prepaid mobile Internet plans, this shouldn't be much of a hurdle.
The app is available for both Android and iOS and I think it would be a good addition to have on your smartphone.
