Stacklog
Did I already take my creatine? Stacklog answers that — and tells you when the tub runs dry
A one-tap daily checklist with morning, pre-workout and evening slots, a servings countdown tied to your actual check-offs, run-out and reorder-by dates, and what your stack really costs per serving and per month. Free, no install, no account.

What you can do in Stacklog on the web
Today checklist by time-of-day slot
Morning, pre-workout and evening sections with one-tap check-offs, a done ring, and arrows back to any previous day — so yesterday's answer is always one glance away.
The shelf, with stock gauges
Every supplement with its dose, form, slot, servings per container and price paid, each with a fill bar showing how much of the current container is left.
Refill forecast
Servings count down with every check-off, and Stacklog projects the exact day each tub runs dry, sorted by soonest reorder-by date with a low-stock list on top.
Cost dashboard
Cost per serving, per day, per month and per year, a ranked spend bar per supplement, and each one's share of the monthly bill.
Your own thresholds
Set the shipping lead time and the low-stock warning level and both the reorder-by dates and the “Reorder now” list follow them.
Stays in this browser
No account and no server — export a JSON backup or a CSV of every check-off whenever you want.

Questions
Is the web version of Stacklog free?+
Yes. Every screen is free to use: no subscription, no in-app purchases, no account.
Do I need an account?+
No. Open Stacklog and start using it right away. Sign in with Google only if you want to upvote an app, save it to your list, or leave a comment.
Where is my data stored?+
Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.
Is there a Stacklog app for iPhone or Android?+
Not yet. Stacklog is a community proposal: the browser version is complete, and we build the iPhone and Android app once 100 people upvote it. Upvoters get one email when it ships.
