If I was planning to switch from Android to iOS, I would consider using an app like this. The question is, do the app itself work well for the use case it is advertised for? Does it actually move your data over to iOS? What data does it specifically move? What does it not move?
I don't care what kind of computers other people use. I write MacOS X software for a living. I chose MacOS X as a user and as a developer for a variety of reasons, but I recognize those reasons may no longer be current. I haven't used Windows since Vista - and my use of Vista was doing development on a cross platform Windows/Mac/Linux app I wrote. I have written software for iOS (before it was even called iOS) and some iPhone apps I've written have been commercially quite successful. I thought about writing software for Android, but I haven't because my understanding is that Android users don't (in general) spend money on apps. I don't like "freemium" apps. I prefer to charge up front or else have it free. These days, I'm really more interested in MacOS X software and Linux software.
That said, I don't care what phone you like. I am very glad there are multiple viable phone platforms. I think iOS is cool. I don't like having to ship software through the App Store. That said, I've certainly sold more through the App Store than I ever sold through other channels like Kagi.
Anyway, I'm disappointed that the conversation here isn't focused on whether the reviews are useful. That's what I would care about.
