I haven't seen any talk of people using Cloudahoy for speed data. Really easy to use and it's free. How accurate do you think it is?
It also works with just an iPad.
I just used it today for the first time. I had it running on my first gen, 3G iPad. I shut everything down but it and Foreflight. Cloudahoy was complaining about memory but was fine after I shut down Foreflight. I guess I'll have to run it on my iPhone.
It worked great except I don't remember landing in a parking lot!
used cloudahoy for a short test flight tonight. It appears to work, but keeps locking up the Cloudahoy program and I'm unable to do anything with it. I use Firefox on a PC for viewing.
I use Ipad in the plane and can see the 2D track on it.
any ideas to try?
