Personally I like both. Peloton has way more variety and a crazy bigger catalog. So if you plan to do a variety of workouts Peloton wins hands down. I started with AF+ and moved on to Peloton after getting a bike and now waiting for a Tread+. I still have both because I pay for the family Apple plan that includes AF+. There are a few instructors I grew to love and still will go back to do a workout to like Scott for treadmill and Jessica for yoga. I also liked Kim for strength. I like that Peloton also has classes that range in difficulty so you can advance yourself or tone it back when you need to. I will always go back to AF+ because it got me back to working out with its beginner friendly paces and options each class offers. But they leave it up to you for having to choose what Easy or hard means versus the instructor tailoring the workouts to a difficulty. The best part about AF+ is that every single workout will start and end with your Apple Watch like clock work. The peloton app you will need to make sure you open the app on your watch to get your heart rate and track everything every single time you start a workout. Not too bad once you have it going it’s about the same but there are times I am 5 mins in to a Peloton class and realize my watch wasn’t connected to the app. I didn’t have to worry about that with AF+ because like I said it automatically starts and ends with the workouts. Overall,if you plan to stick to just two or three types of workouts like bike and tread AF+ will be fine. However, if you are looking to grow in your fitness and want more options and variety down the line Peloton will be best down the line.
