I was standing at a squat rack, with a barbell loaded, trying to do the math. 45 pounds each side, double that, plus the bar… is that 135? 140? I could never get it right. Also: my training app records my weight in kilograms, so now I have to change that on top. I looked at the ceiling, entered numbers into my phone calculator, gave up, and logged “heavy.” This was my life for two years. Then one evening, in about twenty minutes, I created an app that fixed it. The app was embarrassingly simple: It adds up the total weight of the barbell plates I’m lifting, and gives it to me in kilograms and pounds. No social features, no cloud sync, no login even. Just a weight calculator app for my gym. I was stupidly proud of something that took twenty minutes to make.
