MANILA - Google on Friday launched Datally, an app that allows users to cut back on their mobile data costs by better monitoring their usage.

Datally allows users to track their data usage in real time and restrict data access for certain apps. It also has a Wi-Fi finder feature, Google said.

Beta testers who have had Datally since early 2017 said they were able to save an average of 30 percent on data, Google said. Engineering student James Makiramdam said his data allowance was cut by up to P400 per month.

"Kung dati naglo-load ako twice a week, pero with Datally since may control ka na sa data usage, parang kailangan ko na lang mag top-up once a week," Makiramdam said.

(Before, I needed to load twice a week, but with Datally, since it allows you to control your data usage, I only need to top up once a week.)

Datally helps users review their daily, weekly and monthly data usage report, helping them understand their consumption pattern, said the app's product manager, Brian Hendricks.

A bubble showing data use appears every time an app is opened.

"It empowers you to control your data, to make sure that your data goes to the app that you care most about," Datally Product Manager said.

Google recognizes the constant worry of Filipinos that their data balance may not be enough, said country manager Ken Lingan.

"I think as more and more Filipinos growing online through mobile devices. We will continue to make products and platforms to help them make the most out of it," Lingan said.
