RIGIDpro is an advanced bending calculator that was specifically made for helping with Mechanical, Electrical, and Hydraulic Benders. A true respectable side kick to any electrician working with conduit of any type and size. Whether you need to swiftly obtain information about the bender you’re using, or a multiplier card without scrounging through your wallet, or a calculator with the capability of working with fractions (x/16”) and decimals simultaneously, or a bender calculator that accounts for gain and shrink. Allowing you to layout multiple bends on a single conduit quickly. RIGIDpro is your answer. ----- RIGIDpro is broken into 5 different categories. Select Bender: Create, load, and delete benders of various types. Select from several different types of bender styles whether it’s a Mechanical, Electrical, or Hydraulic Bender. All Benders are programmed with the Centerline Radius and Take-Up of the shoe that are based on their factory settings found within their manuals (accuracy may vary slightly). Shoe Specs: Edit and view the information about the selected bender. With a simple click and drag you can change the Centerline Radius (this information can usually be found on the bender’s shoe) or the Take-Up of the specific shoe size being used. Quickly discover additional information about the specified bender’s shoe such as the Gain, Setback, Travel and Radius Adjustment. Mark Conduit: Have a complicated bend? Say a 25” stub, a Three Bend Saddle that needs to be centered 35” from the Back of that 90 at a 22.5 degree interval and needs to clear a 4” conduit, with another 90 66 ½” inches away from the back of the previous 90, and it needs to be cut 25” from the back of that 90. Not only that, but you don’t have the luxury of having a pony handy and you only have a table threader. No problem. The advanced bending calculator of RIGIDpro can handle anything you throw at it. With additional features that allow you to change the conduit size and type; Mark to Center, which deciphers between placing marks at the tip of the hook or the center of the bend; Measure To Center, which will align all bends to the center of conduits, ideal for running raceways with various sizes of conduit. There is the ability to go and edit specific bend measurements; if you wanted the first 25” 90 stub to be 27” without changing the distance afterwards. Also if you have a ground-man and they don’t have the app? RIGIDpro can send them a text with all of the information detailed within the message with a click of the button (make sure it’s okay with them before sending any text messages, all normal rates will apply.). Bends supported are 90 Bends, Offsets, Three Bend Saddle, Four Bend Saddle, Kick with 90 Bends, Kicks, Segmented 90 (3 – 49 shots), and Cut Conduit. With more bends to soon come these bends may be added into whatever sequence you can cleverly come up with. All marks and measurements are based on the push-trough method, from first to last and the Centerline Radius. Multiplier Card: Quickly reference the distance multipliers and shrink constants from 0.5 degree - 90 degrees. Also view the Outside, Inside, and Knock-Out Diameters from ½” – 6” conduit of all types. Calculator: Simple, yet sophisticated. It contains functions such as addition, subtraction, multiplication, and division. Also includes the ability to store and recall memory, squaring, and calculating the square root. The calculator gives you the ability to quickly transpose from Fraction:Decimal and Decimal:Fraction. Easily mixing formulas such as 2.61 x 3 ¼”. ----- If you have any suggestions, or notice any bugs please e-mail me RIGIDpro@outlook.com. I’ll do my best to accommodate to everyone. Hand-Benders are not supported with this app -- only Mechanical, Electrical and Hydraulic. There will be more benders make/models added in the future. ## Key features - Advanced bending calculations - Supports multiple bend types (90, offsets, saddles) - Customizable bender and shoe specifications - Fraction and decimal calculations - Share bending details via text - Accounts for gain and shrink ## Chart rankings - #194 in Top Paid · Productivity (US App Store) ## Recent user reviews (10 of 13) All indexed reviews: https://appshunter.io/ios/app/rigid-conduit-bending-calculator/id788803577/reviews.md ### 1/5 — Works with only one bender type. *2025-09-13* Option to enter a bender, bit won't accept my common Ridgid Ideal conduit bender. Just bought, don't want, don't know how to get money back. :-( ### 3/5 — I don’t understand the marks *2023-04-29* What does a negative mark mean? Is that a measurement back from the obstruction? The app doesn’t give much instruction. ### 2/5 — I bought it can’t figuneed to return it for a refund. Probably good for the right user. *2020-08-10* I bought it thinking it would apply to the hand bender I use, can’t figure out how to ask to return it for a refund. Probably good for the right user. ### 4/5 — Actually very good *2020-03-04* I have used this app extensively for 5 years. It works very good except for one drawback. When you calculate an offset or 4 point saddle where you need to get the rise up before the obstacle this app gives the wrong starting point for the first mark. If you use the start it gives you will hit the obstacle. I find that if I shift the starting point about 4 inches sooner and move all the marks towards the starting point the same amount I can obtain my rise before the obstacle and if it’s a saddle I come off the obstacle right away instead of going 4 inches past it before starting that bend. The data page is very helpful with gain, setback, take up and travel. All around very useful. ### 1/5 — Useless *2019-03-26* Missing benders ### 1/5 — Utterly useless *2018-02-20* No common bender everyone uses, confusing to navigate. Worthless and just used to make the app creator money. Lick my dong. ### 4/5 — Recomendable *2017-02-28* Muy buena app ### 5/5 — Unique *2017-01-25* I have had this app for two years now. Absolutely awesome! I like the way all marks are to the bench mark. No more indexing the shoe for center of 30, 22.5 etc. I like the visual representation of the conduit on the side. It helps you to see if the bends are to close or to far. You can add any bender and tweak the shoe specs to match. Just choose an equivalent Greenlee bender and add a name. I have Ideal and Ericksen hand benders set up as a 555 with EMT shoes, and an Enerpac mechanical sidewinder set up from a 555 with rigid and EMT shoes. All bends are dead on accurate. If you just want the distance between bends, use the multiplier card. Press the multiplier for the degree and it is added to the calculator. If you use it, and get to know how to use it, you will see why I think it's the best conduit bending app. ### 1/5 — Needs more benders!!! *2016-03-07* This app would be cool if it had a user manual and more benders especially for emt. I want a refund!!!!! How do I get it back? ### 1/5 — No good *2015-11-24* Won't allow me to type my bender in the correct spot. Can't access ap without having a bender written in but won't let me write it. Frustrating! ## Frequently asked questions about RIGID ### What types of bends can RIGID calculate?

Hardman ### 1.0.1 — 2014-01-19 -Start Info, now displays when app first opens up, and stops displaying shortly after creating a Bender. -Clicking 'Done' in 'Create' Bender with lack of information now pops up an Alert Window informing you what needs to be completed to create a bender. -Keyboard in 'Create' for 'Bender Name' now closes. -Text Field in 'Create' section is now more obvious. With a place holder of 'Enter Bender Name Here'. -Info on terms placed next to items in 'Shoe Specs' (I'll work on making them a little bit more thorough). -Alert Window pops up when trying to add more bends to a stick after a Cut Mark has been placed informing you that the Cut Mark needs to be deleted before trying to add more bends.
