Now just to busy. ### 5/5 — Great Info. & Great Customer Support *2023-12-06, version 18.9* Being a Union Steamfitter, this App has come in handy countless times! It’s not only easily accessible, but it’s easy to input the pertinent info. to receive the desired answers. I had the app for quite some time with no issues, but at some point it stopped working properly telling me I had to subscribe again. I reached out to Flange Bolt Chart by email, and I was more than pleasantly surprised by not only how fast Joe got back to me, but also how accommodating and supportive he was! Truly, this is win win! It’s not only a great source for the trade/craft, but to have great customer support as well, that’s an awesome combo.! Thank you Joe, and thank you Flange Bolt Chart for delivering a tremendously handy tool for the trade! ### 5/5 — Amazing Application for O&G Engineering *2023-09-20, version 18.8* This application allows the user to quickly get a whole host of useful information when planning flange makeup. It allows us to make quick calculations in the office or in the field without having to fumble with awkward spreadsheets. Thanks so much for the useful app! ### 5/5 — Great and free *2023-08-23* Has everything you need to do hydrotest ### 5/5 — Best app for flanges, studs and specs EVER! *2023-07-13* I work in the energy sector and have used this app for a long time. Working with contractors on the pipeline I get asked about a stud size or correct gasket everyday. Now that you’ve add torque specs, this app is even more helpful. This is a must have app if you are in the oil and gas industry. I would pay for this app anytime. I’ve saved more time on the job, and in turn made more money due to less down time than this app would ever charge. Best yet it’s free! You guys knocked it out of the park with this one. Thank you so much for this app. ### 5/5 — Great app *2023-05-22, version 18.1* If your in this field it’s a no brainer , I stumbled across this app by accident. Was found a bunch of 36” pipe w flanges & valves. It gave me all the info I needed to order correct sizes of bolts & gaskets. I also made a request for more info to be put on the app. Sure enough in about 2-3 weeks info was posted. Great job, I’ll recommend this app to all in my trade. 👍🏻 ### 5/5 — Gas compresión *2022-07-20, version 10.0* Muy útil gracias ### 1/5 — App no longer works gives a black screen and just a grey bar in the middle *2022-04-08, version 8.0* Used to be a good app before the update , was working perfectly before now it’s just a black screen doesn’t even give an option to pick a flange size ## Most critical reviews (10 lowest-rated) ### 1/5 — None *2026-05-28, version 18.26* Does not include stud length ### 1/5 — Used to be good *2025-07-01, version 18.18* This app was way better before they redone it to what it is now. It used to give stud lengths for flange connections now it wants to say more input required. It’s still handy to an extent but the whole stud length is a joke now ### 1/5 — Perfect until…. *2024-10-01, version 18.17* App was perfect until they recently charge you to look up things on it. I was singing this apps praises to the guys and actually working toward getting it suggested for us to download as a requirement at work. I would’ve paid a flat price to buy the app but I’m not paying every month for this. I can check my handy book for this info easily. Uninstalling the app now. ### 1/5 — Greedy app *2024-08-25, version 18.17* It was free for a short time had to subscribe 5 bucks a month. No big deal now I have to upgrade to get any info on bolts. Not only NO but you’re not getting my 5 bucks anymore. Can get the same info for free from google ✌🏻 ### 1/5 — Don’t download *2024-06-11, version 18.16* Had this app for 6 years and now they wanna charge.. deleted ### 1/5 — Sorry *2024-05-14, version 18.16* Trash ### 1/5 — Don’t bother *2023-10-07, version 18.8* It was good while it was free. Just got to troopindustrial.com and use the free chart ### 1/5 — Deleting. *2023-09-12, version 18.8* Been using this app for quite a while now you wanna charge me. Nothing a quick google search won't fix. ### 1/5 — Bad *2022-04-17, version 9.0* After the latest update the app will not even open on my phone. It was very helpful and I used it daily. Now it’s getting deleted ### 1/5 — Broken *2022-04-09, version 9.0* App is broken ## Most praised reviews (10 highest-rated) ### 5/5 — My opinion *2025-10-21, version 18.21* It really helps ### 5/5 — Fieldwork *2025-09-26, version 18.20* I love this app it helps me a lot.

Easy to use. ### 5/5 — Available for windows *2025-05-05, version 18.18* I have it on my phone need it on my windows tablet is it available?? ### 5/5 — Great App *2024-10-31, version 18.17* I use this app at least once a week. Very good accurate data. The one thing lacking is information on Code 61/62 flanges. I have to use a different app for that. ### 5/5 — P/F *2024-10-16* Great app very helpful. ### 5/5 — Very good app *2024-08-29, version 18.17* Comes in handy when you need it ### 5/5 — Outstanding Tool *2024-08-26, version 18.17* Most everything you’ll need, huge time saver, reliable data. ### 5/5 — P/F *2024-08-07* Great app very helpful. ### 5/5 — Works *2024-06-18, version 18.16* Great App --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
