If you track your workouts in your Notes app or a spreadsheet, sesh was built for you. You get the same simple logging. Just tap in your sets, reps, and weight. The difference is that sesh remembers your history and shows you whether you're getting stronger. No more scrolling back through old notes to remember what you lifted last week. Most workout trackers bury you in features, accounts, and subscriptions. sesh does one thing well. It's the simple, honest workout log. WHY SESH IS DIFFERENT • No account. Open the app and start logging. Nothing to sign up for. • Private. Your data lives on your phone, not in the cloud. It never leaves your device. • Simple. Log a set in seconds, then it gets out of your way. WHAT YOU CAN TRACK • Any exercise: gym lifts, bodyweight, cardio, home workouts. If you can name it, you can log it. • Every set, rep, and weight, logged in seconds. • Your full history for each exercise, so you always know your last numbers. • Personal records and progress over time. sesh is for people who don't need a personal trainer in their pocket. They just want a fast, private place to log their workouts and watch the numbers go up. Turn your Notes app workout log into something that actually tracks your progress. Download sesh.
