Your receipt shows a personal license key. Open distilcalc.com/pocket/pro/ on your phone, enter the key once, then Add to Home Screen: it launches like a native app and works fully offline from then on. A single-file desktop copy is included as a bonus, for a laptop in the shed. It is a desktop artefact: iOS cannot open a downloaded HTML file, so on iPhone use the link and Add to Home Screen above. Nothing to install from an app store.
Completely. The whole app is one self-contained file with zero network requests. Airplane mode in the shed is its natural habitat.
Same formulas, different place: the site needs a connection, Pocket does not. Pocket also adds favorites, input history, batch notes and one-tap unit switching, built for a phone in one hand.
Free for life, and automatic on your phone: the home-screen app refreshes itself the next time you open it with a connection. The desktop file is a snapshot, so re-download it from your original link when you want the newest build.
In-depth guides written for home distillers and craft producers — from reading a hydrometer to making clean spirit cuts.
