Turn any workout PDF into a program you can actually track. Upload the plan your coach gave you and PDF Fit reads it into weeks, days, exercises, sets and reps — no manual data entry. Then log every set from your phone. No PDF? PDF Fit will build the program instead. Answer a few quick questions about your goals, your equipment and how many days a week you can train, and you get a complete program built around you. Week 1 is free to train, and it counts: every set you log is real. A FRESH NEW LOOK PDF Fit has a cleaner, calmer design. Today leads with your next session, programs are easier to scan, and logging a set keeps your target and last values right beside you. Choose Light, Dark or System under Theme in your profile. SIGN IN WITH JUST YOUR EMAIL Type your email and tap Email me a link. Open the link on your phone and you're in — no password to remember. New to PDF Fit? The same link creates your account. Sign in with Apple, Google and Microsoft still works too. IMPORT ANY WORKOUT PDF The parser understands real gym programming: supersets (A1/A2), RIR and RPE targets, tempo prescriptions like 3010, rest periods and cardio protocols — so what you get back matches what your coach wrote. OR LET PDF FIT BUILD THE PROGRAM Tell it about injuries or the equipment you actually have and the program works around them. Unlock the full program whenever you are ready, with one free rebuild within 7 days if it isn't quite right. TRAIN IT, DON'T JUST READ IT Log every set with weight, reps and RIR. PDF Fit remembers what you lifted last time for each exercise — even mid-superset — so you can focus on lifting instead of typing. The rest timer has pause, plus or minus 15 seconds and a clear button for your next set, and superset mode alternates paired exercises for you. A SCHEDULE THAT SURVIVES REAL LIFE Choose the weekdays you train under Training Days in your profile. Miss a session and it carries forward onto your next day, with the rest of the week shifting behind it, instead of being silently skipped. TIMED AMRAP WORKOUTS Run "as many rounds as possible" sessions against a countdown with an end-of-round buzzer, then record rounds, extra reps and the weight used. Scores are kept so you can beat your last result. SEE THE PROGRESS Total volume, workouts completed and your personal records, plus estimated strength from your strength tests, over 8 weeks, 30 days or all time. TESTING PROTOCOLS Strength tests with a RAMP warm-up and AMRAP-based 1RM estimation, plus cardio and bodyweight tests, all tracked over time. CHOOSE YOUR HOME SCREEN Four Today layouts — Focused Training, Action First, Coach Brief and Ring & Ritual. Switch any time with a tap. ACTIVE RECOVERY Rest days don't have to be empty. Log a walk, a rest, or a guided 5-pose stretch with a timer on each pose. STRENGTH THROUGH PREGNANCY A built-in 3-day weekly program with trimester-specific modification cues inside every session, an ACOG-aligned safety disclaimer and a red-flag checklist. INTERMITTENT FASTING TIMER Customisable presets, one-tap start and stop, and a clean log alongside your training. WORKS OFFLINE, SYNCS LATER Screens open instantly, and anything you log while offline syncs when you are back. Your workout shows when sets are still waiting to sync, so you always know. 18 LANGUAGES Every screen, label and date is translated into English, Spanish, Portuguese (including Brazilian), Italian, French, German, Dutch, Russian, Greek, Polish, Turkish, Japanese, Korean, Simplified Chinese, Traditional Chinese, Hindi and Indonesian. Weekdays, numbers and times follow your device's region. PRIVATE BY DEFAULT Explore the whole app as a guest, no account needed. When you sign up, your data comes with you. Face ID for quick access, and export your data any time. Your training deserves better than a notebook.
