When it comes to online search, Google is inescapable. Although Microsoft's Bing is gaining ground because of its built-in AI, Google is still the biggest in this field because its search engine is efficient and accurate, making it easy to find what I'm looking for.
I also use the Maps app with satisfaction, especially because of Street View. Their Translator is not perfect, but it is useful, and I like the camera-based translation the most. I also used Gmail for a while and I can't really say anything negative about it, but for some reason I have replaced it.
Apart from these, Google offers a lot of useful services that make life easier for users.
