Here's another interesting app (site) done by a Filipino company - Haybol.ph. The site is essentially a search site for Philippine real estate properties that are either for sale or rent.
The site allows you to search for properties by street, city, barangay or province and aside from just going through a list of properties it offers a view of the exact location using Google Maps.
If you are a seller you can just simply post your listing for free.
You can visit the site at http://www.haybol.ph.
