Frequently asked questions
Can I use it without signing in?
Yes. Choose "Browse" to start without an account, with everything stored only on your device. If you later link a Google or Apple account, your records so far are moved to the server.
Can I move my records to a new device?
If you link an account, your records sync to the server, so signing in with the same account on a new device lets you pick up where you left off. Records made in Browse (local-only) mode stay on that device.
Does it work without an internet connection?
Records you've already loaded are cached on your device, so you can view them offline. Changes sync once you're back online.
Can I import recipes I've been keeping in a spreadsheet?
Yes. After a one-time import from Google Sheets, you can edit and delete those recipes just like ones made in the app. Imported recipes are no longer linked to the sheet, so later edits to the sheet won't show up in the app.
Do I need to create a new recipe every time I change a value?
No. Use "Edit values" on the recipe detail screen to add a new revision to the same card. Use "Duplicate as new recipe" only when you want to branch off into a genuinely different recipe.
When will AI coaching be available?
We plan to add it once enough brew records have built up. It isn't included in the first version.
We usually reply by email within 2–3 business days. When reporting a problem, please include your device model, OS version, and app version so we can look into it quickly.
