Workout log & strength tracker
Only for iPhone

iPhone
Free, with no capped routines and no capped history. 873 exercises, four records per lift, and a rest timer that starts itself when you tick off a set.
Kusog is a workout log. You write down what you lifted, and it remembers.
Start a session, add your exercises, and fill in the sets. Kusog puts what you did last time next to every set and pre-fills the fields from it, so logging a set you repeated is one tap. When you finish, it tells you what you beat.
WHAT'S IN IT
• 873 exercises built in, searchable by name, muscle group or equipment, with instructions. Add your own if something is missing.
• Sets logged as weight and reps, or as time for cardio and stretches. Tap a set number to tag it a warm-up, drop set or failure. Warm-ups stay out of your totals and your records.
• A rest timer that starts the moment you tick a set off. Per-exercise durations, plus or minus fifteen seconds, and a notification when it is up, so it still works with your phone in your pocket.
• Routines. Save the exercises and sets you plan to do and start from them next time. If the session goes differently, Kusog offers to update the routine — and leaves your logged workouts alone either way.
• Four records for every exercise: heaviest weight, best estimated one-rep max, best set volume and best session volume. Underneath, a table of the heaviest you have ever lifted at each rep count.
• Charts for estimated 1RM, top weight, volume and total reps over time. Volume by week, and sets by muscle group.
• A weekly goal ring and a streak counted in weeks, not days, because a rest day should not cost you anything.
• Finished workouts save to Apple Health as strength training, so they count toward your Activity rings.
FREE, WITH NOTHING HELD BACK
No subscription and no trial. Unlimited routines, unlimited custom exercises, and your full history in every chart.
NOTHING LEAVES YOUR PHONE
There is no account and no server. Your training data stays on your device, and Kusog collects nothing about you.
