Google Maps Go shows up on the Play Store for Go phones, but you can give it a try anyway
Android Go, the lightweight edition of Android made for low-end hardware, officially launched about a week ago, and promised to come with several optimized versions of apps to make better use of the limited resources. We've already seen Files Go and Google Go but the Android Go site says there are more apps, like Assistant, Gmail, and Maps. The latter has just showed up on the Play Store, though it may have been available for a while but invisible.
