Learn to make kombucha. Track every brew.
Every brew, recipe and tasting note in one place, so the batch we loved can be brewed again.
iPhone and Android. Paid once on the App Store or Google Play, with no in-app purchases.
What it looks like on the shelf
Four screens from the app: a shelf of jars at different stages, a finished brew ready to be repeated, the moment a batch is started, and the library that comes with it.
Every jar at a glance
Ready, fermenting and finished, each with the days remaining.
Brew the good one again
The amounts, the duration and the notes are still there when we want to repeat it.
Durations with a source behind them
Pre-filled from published sources, and adjustable before we start.
Learn while it ferments
Short articles that read offline, with safety one tap away.
App screens shown for illustration.
Built for the way a brew actually goes
Days remaining, not days elapsed
A ten day brew is a long time to hold in our heads. The ring counts down, and a reminder arrives on the ready date.
Numbers from published sources
Suggested durations come from reviewed brewing guides, a university fact sheet and a state food safety bureau.
What actually went in
Type whatever was used, in the units it was measured in. That record is the part worth repeating.
A good batch becomes a recipe
Rate it, keep it, and start the next one with the amounts already filled in.
Why the numbers can be trusted
Brewing advice online disagrees with itself constantly, and a first-time brewer has no way to tell which page is right. So we read the sources and publish what we found.
Our sources, reviewed in public
A university fact sheet, a state agriculture department, two supply retailers and two working brewers. Every review says what the source is good for, where it is thin, and links to the original. Read the reviews.
The suggestions come from those sources
Seven to fourteen days for a SCOBY brew at 75 to 80°F. Two to five days for a flavor run, kept short on purpose, because a sealed bottle left too long can burst.
What the app will not do
Kombrewcha cannot inspect a jar, so whether a batch is safe to drink stays your call. The safety article states what to check.
One purchase. Everything included.
Kombrewcha is bought once on the App Store or Google Play, and that is the end of it. Nothing is held back for a higher plan.
- No accounts. No email, no password, no profile. Just a brewer name, chosen once.
- No analytics. We collect no usage data. Nobody is counting taps on the other end.
- No tracking. No third-party SDKs, no advertising identifiers, no ads anywhere in the app.
- Works offline. Brews, recipes and every article work with no connection at all.
In the app from first launch
- Unlimited SCOBY and flavor batches, with reminders
- The recipe book, the app's recipes and our own side by side
- The community feed, publishing optional
- Every Learn article, offline
- Every future update to the app
Questions about the app
Do we need an account?
No. There is no email address, no password and nothing to log in to. Publishing a recipe to the community feed uses a brewer name picked in the app, and nothing else.
What is a SCOBY, and does the app help us get one?
A SCOBY is the culture that ferments sweet tea into kombucha. It sits on the surface of the jar and grows with each batch. The article on sourcing a SCOBY covers buying one, being given one, and what a healthy culture looks like.
Does it work offline?
Yes. Brews, recipes, notes and every article work with no connection. The community feed is the only part that needs one.
Can we track several brews at once?
Yes, as many SCOBY brews and flavor runs as we have jars and bottles for. Each one keeps its own duration, countdown and reminder.
Where is our brewing data stored?
On the device. There is no server holding our batches, and we run no analytics and no tracking. Sharing is the only part that reaches a server: a recipe when we publish one, and the brewer name it is published under.
Can the app tell us whether a batch is safe to drink?
No. Kombrewcha cannot inspect a jar, so whether to drink a batch is your call. The safety section states what to check first, including how to identify mold and when to discard a batch.
Which devices does it run on?
iPhone and Android phones. One purchase covers the platform it was bought on, and every future update to the app.
