hello. Has anyone in here used a Sole F80 folding treadmill? And or the application? The app seems to be at least mostly accessible. I don't want to buy the treadmill which is pretty expensive without knowing that other blind people have been able to use it and sync it properly with the application. Also, if you know of any other treadmills that sync with iOS applications please let me know. I considered a pro-form which can sync with iFit Coach software, but I said cost $15 a month which is way too expensive in my opinion. thanks a lot in advance.
