Google Chrome for iOS gets Autofill options, Android gets faster autofill
Given the restrictions Apple has placed on alternative browsers on iOS, Google Chrome simply can't compete in terms of performance; and, maybe that has decreased impetus for Google to push hard on updating the browser. It has been lagging behind the Android version of Chrome quite a bit more than most Google apps, but a new update is closing the gap a little bit.
The Android version of Chrome has had Autofill options for about 7 months now, but iOS is just getting it today. The update will allow you to sync Autofill data between your mobile devices and the web; and, it will also sync passwords across devices. All you'll need to do is be signed-in to the same Google account on all of the devices.
Google has also made Autofill on online forms a lot faster on Android. Merchants can now implement a new feature which lets customers in Chrome for Android to fill in forms using Google Wallet or Autofill data. Google says it should make online purchases much faster on mobile.
