Good
The procedure to migrate Whattsapp chats from Android to iOS is long and painful (about 30 min) but the result is good! And the app is very well designed. 19 euros is a fair price for a good product. Unfortunately, an inaccuracy in the instruction didn't let me grant Whatsapp access to the phone storage (the step-by-step instruction were not applicable to my phone) and all the media in the Whattsapp are just white images.
