WhatsApp Now Lets You Delete and Revoke Messages You Sent by Mistake

The feature is rolling out gradually to WhatsApp users this week.

Clever Camera App Uses Deep Learning to Perfectly Retouch Your Photos Before You Take Them

Professional photographers often spend hours painstakingly perfecting their images in Lightroom and Photoshop before sharing them with the world. But researchers at MIT are promising similar results generated so quickly that your smartphone can correct and retouch a photo before you’ve even taken it.

As with many image-processing breakthroughs we’ve seen over the past few years, the ‘secret sauce’ of this new app lies with an artificial neural network that’s able to learn how to retouch photographs using before and after examples. In this case, researchers used a data set they created in cooperation with Adobe Systems which included 5,000 images that had each been color-corrected and retouched by five different professional photographers, allowing the neural network to generate its own guidelines on what the final result should look like given a specific starting image.

This App Can Scan and Solve Math Equations Instantly

A viral video about a new app looks like a dream come true for anyone who struggles with math.

Based on the promo clip, PhotoMath, dubbed a "smart camera calculator," appears to use smartphone cameras to scan a photo of a math equation in a textbook and display the answer instantly — similar to apps that scan barcodes and takes users to a link in a web browser. It looks like the app can also show step-by-step instructions for solving the problem.

Is There an App That Will Help Your Baby Sleep?

Getting a newborn to sleep, or even just break out of a crying fit, is no easy feat. White Noise helps by flooding baby with soothing sounds, from "Heavy Rain Pouring" and "Ocean Waves Crashing" to "Extreme Rain Pouring" and "Stream Water Flowing." It's easy to switch between sounds and adjust the volume to find the mix that works best for baby. Only one downside: The app doesn't work in the background if you exit it to work on other things. Best to download it onto one of the old disconnected iPhones sitting in a drawer and make that baby's iPhone.
