About this app

Booch is a log for kombucha batches. Follow each batch from first ferment to serving, record what you measure and taste along the way, and keep every reading you have ever taken.

What you can log
• pH readings, plotted as a curve against the 2.8–3.4 finish zone
• Temperature, in °F or °C
• Specific gravity and Brix
• Tastings, scored 0–10 for sweet, tart, tang and vinegar, with a note
• Flavorings for second ferment: fruit, juice or herbs
• Packaging, in bottles or a keg
• Photos from the camera or the library
• Notes

Each batch shows its stage, the day it is on against the days you planned, and a history of everything logged against it. The dashboard lists what is fermenting and which batches are due to be checked.

SCOBYs and recipes
• Keep each SCOBY's parent and generation, divide one, retire one, and see the batches it went into.
• Save recipes and start a batch from one, or rebrew a batch once it is bottled.

Ask Booch
Ask Booch is part of Booch Pro. It can see your batches — their stage, their days and their readings — and answers about them, as well as about kombucha and jun in general. It can look up any batch's readings and tastings. Ask it to start a batch, move one to its next stage, correct a batch's details, or log a reading or a tasting, and it shows exactly what it is about to save. Nothing is saved until you confirm.
Before your first message is sent, Booch asks for your permission, and the privacy policy names the companies that process Ask Booch conversations.

Plans
• Free: two active batches at a time, with full history — every reading and every tasting note — SCOBYs, recipes and photos. No card and no expiry.
• Booch Pro: Ask Booch, and as many active batches as you like. $4.99 a month or $39.99 a year.
Free caps how many batches are active at once. It never caps the history, and nothing is deleted to make room. If a subscription ends, nothing is deleted, and a batch already started can always be finished.

The 14-day trial
A new account gets 14 days of Ask Booch, with a fixed number of messages, on the free plan's two active batches. It is not a store trial: no payment details are asked for, and it does not turn into a subscription. When it ends, the account is on the free plan until you choose to subscribe. It is offered once per person.

Privacy
• No ads, and no advertising software in the app.
• Booch collects its own usage analytics, without a third-party analytics product, and never uses them for advertising.
• Your personal information is never sold.
• Download your data from Settings: every batch, reading, tasting note, log entry, SCOBY and recipe, as one file.
• Delete your account from Settings at any time.

Booch is a brewing log, not advice. Whether a batch is safe to drink is for you to judge.

Booch Pro subscriptions
• Booch Pro — $4.99 per month
• Booch Pro — $39.99 per year
Payment is charged to your Google Play account when you confirm the purchase. A subscription renews automatically at its price, every month or every year, until you cancel it, and it must be cancelled at least 24 hours before the current period ends to avoid the next charge. Manage or cancel it any time in the Google Play Store, under Payments & subscriptions → Subscriptions. Booch has no cancel button of its own, and deleting your account does not cancel a subscription.
Store pricing varies by region — Google Play shows what you will actually be charged.
