Gym

I never liked to use gym apps on my phone. All the ones I found I didn’t like. And i just memorized my workouts. But sometimes I would forget what exercise was next. Then I found StockFit and I would never use another app again. It’s perfect to see my growth. It also suggests what exercises to hit next which is great.

Best clean workout tracker out there!

I've tried a lot of gym tracking apps that feel bloated or hard to navigate while lifting, but StockFit hits the sweet spot. It's clean, lightning-fast to log sets, and gives great insights into strength progression. Essential tool if you take weightlifting seriously!

Clean and Creative

I’ve used plenty of gym trackers, but StockFit’s stock-market approach to gains is easily the most creative concept I’ve seen in a while. Treating your exercises like individual tickers and your entire strength index like a portfolio chart makes progressive overload feel like managing a winning portfolio.
The UI is ultra-clean and intuitive. What really stands out is the polish—the subtle animations, smooth screen transitions, and tactile feedback make logging a set quick and seamless during a rest interval. The workflow stays out of your way so you can focus on lifting, but the visual progression keeps you motivated to log the next session. Hands down one of the most refreshing fitness apps on the App Store right now.
