What you can do in Brewlog on the web
Urgency-sorted ferment dashboard
Active batches group into Past target day, Ready soon and Still fermenting, each card showing a type badge, day X of Y progress bar and the last reading.
Four batch types with their own units
Beer and cider log gravity in SG to three decimals (21 and 28 day defaults); kombucha and kraut/kimchi log pH to one decimal (10 and 14 day defaults), with the right range hint on every entry.
Reading timeline and chart
Each batch gets a line chart of its readings plus a dated timeline with the note you wrote at the time, and the total drop from first to last reading.
Recipe kept with the batch
Paste the grain bill, hop schedule, brine ratio or SCOBY notes into the batch and it stays attached — then brew it again in one tap.
Tasting notes and searchable archive
Rate a finished batch 1–5 stars with a Drain pour to Perfect! label, write what you'd change, archive it, and search the vault by name or type later.
Your data, exportable
Everything is saved in this browser only; download a JSON backup or a CSV of every reading for your spreadsheet.

Questions
Is the web version of Brewlog free?+
Yes. Every screen is free to use: no subscription, no in-app purchases, no account.
Do I need an account?+
No. Open Brewlog 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 Brewlog app for iPhone or Android?+
Not yet. Brewlog 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.
