Questions

What do I actually get?

Pocket is a web app: all 33 calculators in one file that installs on your phone and works offline. The Field Guide is a PDF of 22 printable pages, in metric and US editions.

Are these the same formulas as the free site?

Identical, including the OIML density table and the NBS alcoholometer corrections. Same source library, same numbers.

Metric or US?

Both. Pocket switches with one tap. The Field Guide ships both editions in the same download.

Does Pocket need a signal?

No. Once it is installed it runs with no connection, no account and no sign-in. There is nothing to log into.

What about updates?

Free for life. Pocket updates itself the next time you open it with a connection, and your original download link always serves the newest Field Guide.

Refunds?

14 days, no questions. If it does not earn its place in your workflow, email and it is refunded.

Stop losing your numbers.

The offline app and the printable guide, in every edition, for €2.95 less than buying them separately.
