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.

What's inside

• Today checklist — A single daily screen groups supplements into morning, pre-workout and evening slots with one-tap check-offs, a done count, and a swipe back to review any previous day.
• Stack shelf — Add each supplement with name, form (powder, capsule, gummy), dose, time-of-day slot, servings per container and price paid; the detail view shows its computed cost per serving and servings remaining.
• Refill forecast — Computes servings remaining from check-off history and doses per day, projects a run-out date for every container, and sorts the list by soonest reorder-by date with a low-stock highlight.
• Cost dashboard — Ranks the stack by cost per serving, totals cost per day and per month, and shows each supplement's share of monthly spend so cuts are obvious.

Why we built it

People taking multiple daily supplements have no operational system: they forget whether they already took today's creatine (consistency is the whole point of saturation-based supplements), have no idea what their stack costs per serving or per month, and only learn a container is empty when the scoop hits the bottom…

What makes it different

Unlike pumpwise (a breast-pumping session and milk-stash log for new parents) and dairylog (per-animal milk yield records for livestock keepers), Stacklog is a consumer supplement-routine manager — and unlike the portfolio's stackup, which evaluates whether a stack makes scientific sense, Stacklog never opines on effi…

Who it's for

Anyone who wants honest tracking without a coach, a subscription, or a streak guilting them at 11pm.
