Interesting, definitely, and (IMHO) helpful if you are not familiar with the London tube system. There is far more to the app than simply maps of tube stations. There is detailed information about facilities available at each station as well as related bus line information and more. As a visitor I find it very helpful, even after many visits to London. Residents/regular commuters who are thoroughly familiar with their usual stations and stops might not be interested and wouldn't learn much.
