Hop to it
I downloaded beercalc for the phone, which TBH is mostly what I use round the brewery(phone). The app is free and has 5 timers which I can set for either step mashing or the hop schedule.. It ain't fancy but I like it, I've tried many of the others out there and rekon this one suits my process down to the ground.. God knows how many timers I've tried over the last year...
