Is there an easier way to compare iOS to Android apps than manually checking each app? Next year, I'm getting myself a new phone, and it'll either be a Nexus or an iPhone. I'm currently using a Samsung Galaxy S4, but I'm fed up with how slow security updates occur and how often Samsung installs random crapware on my phone that I didn't ask for. In addition, the S4 is at the end of its lifecycle and might not get a full version of Android 6.0.

I'm currently verifying whether switching to iOS won't lock me out of any of my apps. I have spent barely any money on in-game app purchases for Android, so that's not holding me back. However, I have a number of apps that I use weekly, often even daily, and I want to make sure I still have access to those, or at least something similar.

I could manually check each app on the itunes store, but that's a long and manual process that I would prefer to keep as a last resort. Is there an easier way to check what Android apps are available on iOS or at least have something similar?
Borrow an old iPhone and run the Apple migration tool by following the setup directions on iOS 9 or you could use the Relo tool to attempt a dry-run on the Android side.

That way, you can actually use the new OS for a bit and if it's unlocked, you could swap SIM cards between the two devices. If you don't mind the cash outlay, you could also buy a new phone outright and educate yourself on the return policy if you're mostly sure the change will be for good.
