This app meets that goal. Thanks! ### 3/5 — Easy to use, *2016-02-25* Need to fix the calendar calculation, show 26 weeks from a date 2 months from now, it is off by 6 days, using the weeks function for this, I still like the app, ### 5/5 — Neat! *2015-05-08* Very useful and easy to use. I only wish I could have found earlier this app. Great! ### 5/5 — Perfect *2015-04-22* Works great and just like the original "analog" version. Simple is best. Please don't "improve" it. ### 5/5 — Very useful *2014-11-26* I saw a physical wheel like this from a local CAT gen dealer and found this app to be the closest to it on here.I love the simplicity and ability to easily maneuver, as opposed to the other products out there that I tried. ### 4/5 — Great Lead Time Calculator *2014-02-21* No documentation but after working with it figured it out. It is perfect. Prefer not to have ads but don't find a non-lite version or anyway to remove ads. ### 5/5 — Works great *2013-09-10* You CAN calculate both ways, if you figure out how to spin to the other side of Zero. Green date is the start, red date is the finish. They'll swap at zero weeks. Previous negative reviewers must have a 4 second attention span, and want all thinking done for them. ## Frequently asked questions about Lead Time Lite ### What is Lead Time Lite?
