Added aerobics exercises that correspond with Apple's fitness app and can track heart rate/zones of your Apple watch

Rest timer — optional, and off until you switch it on in Settings. With it on, a rest is counted after every set you log. Roll a wheel to what you just lifted and the rest starts; a countdown covers the screen, and "skip rest" ends it early. You can pocket the phone while it runs. A notification arrives when the rest is over, and if you have an Apple Watch nearby, it taps your wrist.

Statistics The logs screen becomes logs/stats, with four tabs. Graphs show how your estimated one-rep max is moving for each exercise, with a trend line. Progress ranks your exercises from least to most improvement, so whatever is stuck is at the top. Both appear once you have logged an exercise in eight workouts. An exercise library Ready-made exercises for every muscle group, so you need not describe each one yourself. Find them on a body diagram — tap a muscle to see the exercises for it — or by plain buttons if you prefer. Star the ones you use most. Muscle groups Every exercise records the muscles it works, which is what the diagram and the filters go by. Simpler editing One screen for all your exercises. Drag to reorder a workout instead of opening a separate screen. Names must be unique, and nothing is saved until you tap save. Optional sharing You can now share your logged sets anonymously to help improve the app. It is off unless you turn it on, it never includes your name or your exercise names, and turning it off deletes what was shared.

Added Apple Watch companion app and option to share workout time to Apple Health/Fitness.

Compacted log screen, option to share data among iOS devices, added JSON download.

Improved the sensitivity to swiping in the "Log Exercise" screen.
