Fit4i: Gym Workout Tracker

About this app

Every fitness app asks what you did. Fit4i decides what you do today — and tells you why. Slept four hours? Today's session is already lighter — and you still don't lose the week. TRAIN SMARTER A log stores the past. A coach makes a decision. Every morning Fit4i has today's session waiting — exercises, sets, reps and working weights, already chosen. A readiness score built from last night's sleep, HRV and resting heart rate (Apple Health — or a ten-second check-in if you don't wear a watch) shapes the plan. Tap "Why this workout?" and it walks you through the reasoning, the way a good trainer would. PROGRAMMED LIKE A COACH, NOT A CALCULATOR • Exercises picked the way a trainer picks them: the main lift opens the day, every leg day trains the posterior chain, pressing and pulling stay in balance. • Warm-up sets calculated from your working weight — right on the workout card. • Weights and reps advance on their own as you get stronger. Volume climbs in waves and backs off in planned deloads — real periodization, not "add 2.5 kg forever". • New to lifting? You start with movements you can actually do — assisted variations instead of strict pull-ups on day one. • Something hurts? Report it: risky movements disappear, the rest carries a "careful" note — instead of your program losing half its exercises. MASTER EVERY EXERCISE Step-by-step 3D guides for every movement: setup, working phase, return. What you should feel and what to avoid — in plain language. TRACK WHAT MATTERS Calorie, protein and fiber targets tied to your goal — and they shift as your bodyweight trends. Log meals in seconds, scan a nutrition label, track water, and add supplements with the scoop math done for you. IT BENDS TO YOUR LIFE • Twenty-five minutes instead of sixty? One tap reshapes the session — the main lift survives. • Back after weeks off? Comeback mode rebuilds you gently. No guilt, no injuries. IT LIVES ON YOUR LOCK SCREEN Start a session and your workout appears on the Lock Screen and in the Dynamic Island: current exercise, set count, and a rest timer that counts itself down. On iOS 17 and later you can log a set without unlocking. The phone stays in your pocket, where it belongs. COACH-LEVEL PROGRAMMING. NOT THE COACH-LEVEL PRICE. Free forever: build your program, log every workout, and watch your working weights advance automatically — plus full nutrition, water, bodyweight and supplement tracking. Your first 7 days of Pro are free. Pro adds the thinking layer: programs built around your goal and level, periodization with planned deloads, recovery-driven daily adjustments, and calories that adapt to your weight trend. The subscription renews automatically; cancel anytime in Settings. Works in kg or lbs — at the gym, at home with dumbbells, or with nothing but your bodyweight.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
