You no longer have to scour for Google Inbox updates. Google announced at its I/O developer’s conference that the email client is now available for download from the Google Play and Apple App Store.
The app also now has a much-requested Undo Send option. It also now shows your reminders in Google Keep inside Inbox. And Trip Bundles automatically collates your trip-related emails and highlights the key information you’d need. Inbox now also supports custom signatures and you can enable a “swipe to delete” gesture as well.
