Questions, bugs, or a calculator you wish it had: email support@mimssoftwareco.com. Tell us your phone model and the app version (Settings → About).
Tap ft after the feet and in after the inches: 5 ft 7 in 3/8. A fraction always belongs to the inches. A number on its own isn't a length, so if you type 16 with no unit the app asks "Feet or inches?" instead of guessing.
On purpose. Take-outs, make-ups and radii change with the maker, the schedule and the joint, and a number from somebody else's table can be wrong for the fitting in your hand. Soapstone ships with no fitting or pipe data. Add your fittings once (Settings → Your lists → My fittings, or "From my fittings" under any take-out) from the maker's sheet or your tape, and every calculator reuses them. For welded elbows, enter the nominal size and the app offers the usual rule of thumb as a starting point.
Every calculator shows "The math" under the results: the formula with your numbers in it. The ⓘ button at the top explains the inputs and walks through an example.
Answers are rounded to the precision you pick in Settings. "Strong" means the true length is a hair over the mark shown; "shy" means a hair under.
Sign in to the Play Store with the same Google account, install the app, and open Settings → Unlock or restore Pro → Restore purchase. Pro is tied to your Google Play account, not to the phone.
Purchases go through Google Play. You can request a refund through Google Play's refund process, or email us.
Soapstone does the arithmetic. It doesn't know your job, your materials, your fittings or local requirements, and it isn't engineering advice. Check every number before you cut.
