What Pro keeps

The calculators are free for ever, with no account and no trial clock: a brewer standing over a fermenter with a hydrometer in one hand should not have to sign up to find out what the reading means. Mashzo Pro is £3 a month and keeps things, every recipe, every brew day's readings, and the figures your own kit actually produces, so the next brew starts from the last one instead of from the defaults.

Should you just use a full brewing suite?

If you want recipe design, a hop and malt database, water chemistry and a mobile brew-day timer in one place, buy a full brewing suite: they are good and they are cheap. Mashzo is for the brewer who wants the three sums done right, with the constant named, and the readings kept.

Prices and features of other brewing software change; nothing on this row names a competitor's price, because we do not publish figures we have not measured and dated ourselves.
