After I bought my ANT+ case for my iPhone, I literally spent a couple weeks obsessing over what app I was going to buy to go along with the new hardware. After a lot of consideration I bought BikeBrain. I thought hands down it had the nicest user interface, and it appeared to do everything I wanted it to do. With a deep breath, I hit that "BUY APP" button. Well, after getting the app installed, and my phone seated in the ANT+ case, I hopped on the bike for a test ride. Pretty quickly I regretted the purchase, realzing that lack of heart rate, and cadence, make this app pretty much useless. As there are many other FREE apps out there, giving me the functionality I desired. Oh well, too good to be true. Its too bad, at $1.99 for the purchase, I would have appreciated it if the screen shots didnt mislead (as well as others) to think that these other features were available. Looks like other reviewers have been waiting much longer than I have, so I guess its time to move one.
