Would recommend. ### 5/5 — Great little app... *2020-05-23, version 1.9* Does exactly what it says on the tin. Nice and easy to use with no ambiguity, just what I needed. ### 4/5 — Spare, but works *2019-08-12* Note to users: the units are irrelevant so long as you’re consistent. The units don’t have to be all metric or all English. e.g. : if you use furlongs for both lengths and kg-inches for both torques, you get the right answer. It’s also important to know how to use a torque wrench with an extender: - Always keep the wrench and extension in line. (Not at an angle) - Always push from the center of the torque wrench’s handle (or wherever you measured L1 & L2 from) If you do those, it works great! ### 4/5 — Amazing app *2017-10-01, version 1.7* Use this app daily in work however since ios11 update it no longer works :( ### 3/5 — Meh *2014-12-08* I have no idea what units this program is asking for or giving me ### 5/5 — Very Handy! *2013-03-21* Very quick and easy to use. Remember to always use the same units! ### 4/5 — Works as advertised *2012-09-22* Formula is the same as what is in Sikorsky's standard practices chapter. App gave the same answer as my calculator when given the same numbers. ## Frequently asked questions about Torque Wrench Extension Calc. ### How does Torque Wrench Extension Calc. work?
