I am considering buying a Cyclops Hammer since it is so affordable. I have a question concerning the apps that could control these. I'm not interested in any of the social media type apps like Zwift at this time, just trying to privately train. I presently use an old used Elite fluid wheel-on unit right now, and just shifting gears for resistance is somewhat random. You don't really train to do a segment easily that way.

If I were to buy one of these two units, would I be able to take a well defined or even created route that I've ridden before, and then ride that route in the evening for training? I currently create my routes on Strava, then load to my Roam and ride them, recording to it and Strava. But can that route then be fed back into some app with the GPS information to simulate it in my living room on one of these units? If it's possible, what app would I need for an iPhone to drive one of these units?

As a side note, is there any reason the Hammer is a poor choice over Tacx or the Wahoo unit?
