It's exactly what I always do, especially for fastest transfers and being the first one on the stairs. Recently I have been taking the 6, L and G a lot, terra incognito where your app comes in fitting perfectly. Love it! Edit: Installed it, very smooth operation, took less than 6 seconds to find a perfect exit strategy for L -> 6 train transfer. Nice!
