Main Feature - Support more than twenty popular apps - Launch search with just one hand - Support custom search target - Support for iPad Design concept The OneSearch design concept is to make a great search box and link it to the search function of other apps. Make in-app search a one-step experience. We wanted to optimize the complex interaction of having to find the app, then find the search function in the app, and then enter text. In OneSearch, you just type, click, and do a search.
