Changes in Apple's app store. The tech giant says that of January the first it's no longer accepting 32-bit apps in its app store. Google has followed suit in rejecting 32-bit apps but has given developers more time to update their programs.

Apple says that new submissions to the App store must be 64 bit only as of January the first. However, Apple said developers need to update their existing 32-bit apps before June. Apple's Mac OS "High Sierra" will be the company's last operating system to support 32-bit apps. There are 187 thousand 32-bit apps in the Apple Store, about 8 percent of the total apps.

Google is the latest tech company to focus on 64-bit apps and devices. But unlike Apple, it will continue to support its older 32-bit apps and devices. Google said its Google Play will require new apps and updates to include 64-bit versions starting in August 2019. New apps and updates should target the most recent Android API levels. In addition, developers will also be required to add security metadata to each app. The move is part of Google's effort to ensure security and performance for smartphones. 64-bit support for apps was introduced in Android 5.0 but Google now has made it mandatory. Google said over 40 percent of the devices coming online these days have 64-bit support along with 32-bit compatibility.
