Stacklog: supplement stack & stock tracker

About this app

What Stacklog does

Stacklog is the supply-room manager for your supplement stack. Add everything you take — creatine, magnesium, vitamin D, omega-3, protein, whatever's on the shelf — with its dose, form, and the time of day it belongs to. From then on, your whole routine lives on one screen instead of in your head. Every morning the Today checklist answers the question every supplement-taker asks at some point standing over an open tub: did I already take this? Tap to check off each item in its slot — morning, pre-workout, evening — and yesterday's answer is always one glance back. No streak shaming, no coach-speak, just a clean record of what actually went down the hatch. The part nothing else does well: logistics. Tell Stacklog the servings per container and what you paid, and it quietly counts down inventory with every check-off. The refill view forecasts the exact day each tub runs dry and lines up reorder-by dates soonest first, so you never face a Monday with an empty creatine tub and a five-day shipping window. The cost view turns label math into real numbers — cost per serving, cost per day, and what your full stack actually runs you per month. Stacklog is completely free, works 100% offline, and asks for no account — everything is stored on your device with SwiftData and never leaves it. Your supplement routine is nobody's marketing data. • One-tap daily checklist with morning / pre-workout / evening slots • Per-supplement dose, form and timing • Automatic cost per serving and monthly stack spend • Refill forecast: run-out dates and reorder-by warnings • Servings countdown tied to your actual check-offs • 100% offline, no account, no subscription, nothing shared If your stack has outgrown your memory, download Stacklog and put it on the shelf where it belongs.
