Gaming on iOS is extremely underrated. I say that as someone who plays Call of Duty Mobile just about every day on my iPhone. Sure the screen is a little small, but the graphics look great, and my Bluetooth controller makes it feel almost exactly the same as it does on a full-blown console.
If you don't already have a controller, you need to get one ASAP, especially since Apple is now allowing game emulators in the App Store. There's already a fantastic emulator available, with full gamepad support, called Delta, so we thought now would be a great time to review the best Bluetooth controllers for iPhone.
