OLBip is an Android app developed by Paulo César, available for free in the Lifestyle category. It is a powerful tool that tracks thousands of ads on the biggest ad portal in Brazil, OLX. With OLBip, you can create alerts based on various criteria such as region, category, advertiser name, keywords in the title and description, price range, and more.

The app is incredibly user-friendly, and you can create alerts for a specific car, your dream home, or even a collectible item you've been searching for. OLBip will notify you as soon as a new ad matches your criteria.

When you click on an ad, you will be redirected to the ad display in the app. If the app is not installed, the ad will be displayed in your browser. It is essential to note that OLBip has no affiliation with OLX. Also, this app only works in Brazil.
