AGUNA

Walk into the gym knowing exactly what to do. AGUNA builds your week from the goals you pick, with rest days built in, then gives you each session in order: one or two muscle groups, the exercises, sets, reps and the weight to use. It remembers what you lifted last time and puts the weight up when you hit your reps. If a machine is taken, Machine taken? moves a free exercise up; if the whole gym is packed, Busy gym? switches the session to dumbbells. Meals are planned too, and you can snap a photo of your plate to count calories. The first full workout is free. On iPhone, iPad, Apple Watch and Android.
