StockFit is a strength training log that charts your progress the way a market charts a stock. Every set you finish moves your Strength Index — one number built from your estimated one-rep max across thirty core lifts. Open the app and you see a line, a change since last week, and the lifts behind the move. Progress stops being a feeling and starts being a chart you can read. CLIMB THE TIERS Your Strength Index climbs a ladder, from Penny Stock to the Trillion Dollar Club. SET A PRICE TARGET (STOCKFIT+) Aim any lift at a weight and StockFit draws the line from where you are to where you're going, with a ring showing how far you've come and the month your current pace gets you there. LOG A SESSION WITHOUT FIGHTING YOUR PHONE Tap a set to complete it and the rest timer starts on its own. Previous weights and reps sit right where you need them, carried from the last time you actually did that set. A gold badge marks a personal record the moment you hit it, not at the end. THE REST TIMER FOLLOWS YOU OUT OF THE APP Lock the phone and the countdown keeps running on your Lock Screen as a Live Activity, turning green the second it's time for the next set. A MUSCLE HEATMAP AFTER EVERY SESSION (STOCKFIT+) Front and back body maps shade by how much each muscle actually took, derived from per-exercise contribution weights rather than a single tag per lift. You can see the session you actually trained. ROUTINES, SUPERSETS AND MERGES Build routines, drag to reorder, group supersets, and merge two routines into one session when the gym is busy and you have to improvise. Machine taken? Replace suggests the lifts that work the same muscles first. APPLE WATCH Start a session on your wrist or mirror the one running on your phone, with heart rate, zones and measured calories from the Watch itself. Log sets, run the rest timer, and sit out a lost connection — the Watch keeps the session and hands it back when the phone is near. WIDGETS AND SIRI Home Screen and Lock Screen widgets for your Strength Index and its recent line, your streak, the week so far, and a one-tap start for today. Ask Siri to start a routine, or how your Strength Index and training week are doing. BUILT FOR PEOPLE WHO DON'T WANT AN ACCOUNT There is no sign-up, no email, no ads, and no analytics.
