I have this one -
http://www.decathlon.co.uk/flow-smart-turbo-trainer-id_8345488.html I _think_ its the 2240. It is FE-C compatible and therefore works with Zwift etc. I've used it on Zwift and Golden Cheetah; so in theory as BKool supports FE-C in their app it should work.
Bear in mind it is rated at max 700W for 30s so if you're training to be a sprinter its probably not going to be quite enough...
The only other thing I discovered too late is that it will only take 26" to 700c wheels and there are some options (albeit more expensive) that go right down to 20" wheels (which would have been handy for me as the moment my son saw me on Zwift he wanted a go too...)
Overall for a 'cheap' trainer I'm very happy with it.
