It's not just Facebook and Google who are slimming down their mobile apps for the sake of regions where data is slow or spotty. Twitter has confirmed to TechCrunch that it's testing a native Android equivalent to its Lite website in the Philippines, where slower phone networks and limited phone storage make the standard app less practical. While many of the core Twitter functions are still there, the focus is on cutting out all the media that chews up valuable bandwidth. There's a "Data Saver" mode that avoids displaying pictures and videos unless you opt to see them, and Twitter says it can use up to 70 percent less data overall. Even the app itself occupies just 3MB of space.
