I knew about Google Translate and have used it a few times, but there's a related feature that is a real game changer. It's called Google Lens. You point your cellphone camera at something in a different language and ... it translates it in real time right on the screen in front of you! I just thought this was quite amazing and quite useful.
We had to fill some prescriptions in Austria and only got a little guidance from the pharmacist. So voila, back in the hotel room we aimed our cameras at the packages and all was revealed! What the ingredients were, how often to take them, what they were supposed to accomplish. Astounding.
And then, we were at the market trying to buy some decaf coffee. Naturally assumed that the word would be similar to English so should be easy to spot. Nope. Found a likely bottle of Nescafe and pointed the camera and ... magic!
I'll save you the trouble, the word is entkoffeiniert. Never would have gotten that one. Also noticed that there were several other people at the market also translating product labels. I don't say this too often, but thank you Google!
