Fit4i: Gym Workout Tracker

Tap an exercise, type weight × reps, tick the set — done. Setup is 3 quick questions — age, sex, body weight — then you're logging.
Next time the exercise opens pre-filled, "Last time: 60×8, 8, 7 · 3 days ago" right under the name. Rest timer and personal records: automatic.
Want a plan instead? Say so on the first screen and Fit4i Pro builds one from your recovery and equipment. Either way, every set feeds the same 14-zone muscle map — it knows what has recovered and what's overdue.

LOG THE WAY YOU ALREADY TRAIN
Pick "I train on my own" and Home greets you with "At the gym? Start here" — one tap opens an empty workout. Add exercises — or create your own — type weight and reps, tick the set. Hit every rep? A quiet line says "All sets hit — try 62.5 kg?" — one tap to take it, none to ignore it.

YOUR ROUTINE, BUILT FROM WORKOUTS YOU ACTUALLY DID
Finished? One card asks "Save as a routine day?" — no builder to fill in. Save a second one and you have a split. From then on every slot carries a target: fill the rep range and the weight steps up. Three sessions in range without reaching the top? A stall line offers a swap, and swaps are remembered. Need a break from targets? Pause them; when you resume they catch up to your latest weights, never down.

THE MUSCLE MAP DOESN'T DECORATE. IT DECIDES.
Fourteen zones, each recovering from the sets you logged — weight, reps, how long ago. On your own routine it shows what you trained yesterday, what fell behind this week, and how many sets each zone got. Pick "Build My Plan" and every morning the map serves the day your body is readiest for and says why in one line. A main lift that has waited too long goes first — so your deadlift never quietly disappears.

STILL A PROGRAM, NOT A SHUFFLE
Fit4i keeps the structure: main lifts come back on schedule. Weights and reps advance on their own. With Pro, volume climbs in waves (on auto-built programs) and backs off in planned deloads — real periodization, not "add 2.5 kg every time".

YOUR SLEEP IS AN INPUT, NOT A STATISTIC
Sleep, HRV and resting heart rate come from Apple Health — or a ten-second check-in if you don't wear a watch — and they shape today's session, not next month's chart. Awful night or feeling off: a lighter session for everyone; with Pro, so-so days keep a rep in reserve too. Feeling fine anyway? Say so, and the plan believes you.

IT BENDS TO YOUR LIFE
• 25 minutes instead of 60? One tap compresses the session — the main lift survives.
• Missed a few days? No guilt screen — the muscles that fell behind catch up.
• Skipping the plan today? "Empty workout" is always there — log, map and records still count it.

ALSO IN THE BOX
• Apple Watch: today's plan, set logging, rest timer and heart rate on your wrist.
• Pro: meals by photo, label or text.
• kg or lbs — gym, home or bodyweight.

FREE TO LOG. PRO WHEN YOU WANT IT TO THINK.
Free: the log, your routine days with slot targets, "Last time", history, personal records, the muscle map, the check-in, the readiness ring and the food log.

Pro decides for you: the auto-built program and its rebuild, recovery tuning every day (not just the worst ones) and early deloads, planned deloads and volume waves, meals by photo, label or text, and adaptive calories. Your first 14 days of Pro are free: no purchase, no payment details (on your own, they start with your first finished workout on a saved routine day). After that you stay on Free unless you subscribe. Pro is an auto-renewing subscription; eligible new subscribers get a 2-week free trial through the App Store, which needs a payment method on your Apple Account. Cancel anytime in your Apple Account.
