Features
Everything you need to log, program, and review.
Obsidian is a workout tracker for serious athletes. Log weights, calisthenics progressions, and cardio. Track PRs for weight, reps, and hold time. Fully featured with no paywall.
Core features
Four pillars of a complete training log.
Log, program, review, and back up. Everything you need in one app — nothing locked behind a paywall.
Log
Log sets without friction
Record weight, reps, hold time, and RIR or RPE for every set. Mark warmups, working sets, and dropsets. Rest timer and hold timer built in.
Program
Run structured programs
Build multi-block schedules with training and rest days. Start today's workout from the home screen and pick up where the program left off.
Review
Review what you actually did
See personal records, weekly volume by muscle group, and cardio totals. Export set history to CSV when you want a spreadsheet.
Backup
Your data, your choice
Use the app as a guest with local storage, or create an account to back up workouts to the cloud. Export or delete your data from Account settings.
Training workflow
Covers each part of your training week.
From the first warmup set to reviewing last month's volume, each step has a clear place in the app.
Logging
Active workout logging
Move exercise by exercise, log each set, and let the rest timer run between sets. Add or remove exercises mid-session without losing data.
