A new week has dawned, and with it comes a new list of great things happening on Android. This is the Google Play App Roundup where we tell you what needs to be on your phone or tablet right now. Just click the links to head to Google Play and grab these apps for yourself.
Good old control-f is one of the most useful keyboard shortcuts, though some people still don't even realise it's a thing. Crazy, right? What if control-f existed in real life? I'm sure people would want to know about that. CTRL-F for Android aims to be just that, a real world version of the find command. It won't find anything, but it's pretty good at scanning text and making it searchable.
CTRL-F is basically a fancy interface for optical character recognition with search built right in. To start using CTRL-F, simply find a document you want to search, and use the app to snap a photo (or import an existing image). Printed text works best, and the font needs to be at least somewhat conventional. Really weird stuff might now be detected correctly. After you take the photo, CTRL-F lets you frame the text for better detection.
The app then processes the image by straightening the font and reading it. It supports over 50 languages, but I only tested it in English. The entire scanning process takes about 20 seconds for a single dense page of text. The processed image you get looks like a very high-contrast version of the photo you took, but behind the scenes is a full searchable text document.
The accuracy is surprisingly good for most documents. I've found that glossy materials tend to cause more issues than those on matte paper. Varying fonts also seem to cause issues. Searching is fast and accurate most of the time, though. All the documents you've imported and had scanned will remain available from the main screen in CTRL-F.
The data in CTRL-F isn't stored as some wonky non-standard file. If you want to export a searchable PDF, the option is available in the overflow menu. I'd like to see some sort of batch processing mode in CTRL-F, but the current functionality isn't bad, especially when you consider it's free.
