I use beersmith and like it a lot. I only have it on lap top so far, did not pay for mobile upgrade. I have trial of pro mash on laptop as well but after beersmith, it does not seem as user friendly. I know it's well loved, but I found it tougher to find my way through it in comparison. It just did not seem as user friendly, seemed to require a longer learning curve than beersmith. Just my opinion, as I know others swear by it, or at least did while it was regularly uodated
