Pricey, but it worked great!
It worked really well, it's just expensive. I like that it walked me through the whole process for transferring WhatsApp messages from my iPhone SE to my new Pixel 4a, and while it took a little while to get it set up and transfer everything, it worked like a charm in the end. I had to do a little troubleshooting when my Pixel wouldn't recognize that the Connector app needed to be downloaded, but fiddling with some of the USB settings did the trick. The main reason I knocked one star off is for the price - $40 for a year or $50 for a lifetime subscription seems a little steep for something that I may just use once or twice, and that's just for the WhatsApp transfer capabilities. And for some reason, the Mac version is $10 more than the Windows version, so I'm stuck paying more overall. That said, it worked exactly as intended, and now I have all my old WhatsApp messages and media on my new phone. If the price is within your range, I definitely recommend this product for cross-platform data transfers. I got the lifetime subscription, so if I ever switch back to an iPhone, I'll definitely be using this again.
