I'm just a bit disturbed that I was charged $33.11 immediately after clicking to start the free trial. Seems a bit disingenuous from my perspective. I will never mind paying for an app that continues to improve - just figured that the free trial was actually free. ### 4/5 — Almost *2025-07-17, version 10.7.0* 4 stars so they have something to work for ### 2/5 — Eric *2025-03-11, version 10.5.7* I have this app for years, and since I got a new phone now the app doesn’t work. I hope that I don’t have to pay an annual subscription since I’ve been having this app for long. How can I solve this issue? ### 4/5 — Used to be one time pay *2025-03-07, version 10.5.7* Does that job like the physical one ### 2/5 — Watch out *2024-12-31, version 10.5.7* Love using this app but where I work I don’t get service and it doesn’t let me use it because it cannot verify I have a subscription. Paid for a yearly subscription just for it to not work. :( ### 2/5 — Already own the physical calculator *2024-11-04, version 10.5.2* I should be able to access the digital version since I’ve already paid $70 for the physical calculator. Why is this not an option? ### 5/5 — Pipepro calculator *2024-09-23, version 10.5.2* Thank youuuuuu! ### 5/5 — Pipe trades pro *2024-09-16, version 10.5.2* This is my go to app while out in the field making calculations. Use this app daily. Thank you for this app. ### 5/5 — Ecelent *2024-06-20, version 10.5.2* Ecelent ## Most critical reviews (10 lowest-rated) ### 1/5 — No *2026-07-20, version 10.7.0* Why do you have to pay yearly for app why not pay once and own it the calculator is same price on amazon ### 1/5 — BS *2026-07-08, version 10.7.0* They charged me on the first day 10$ then they did not give me 2 weeks free trial. It supposed to be 4.99 for the first charge ### 1/5 — Poor value *2026-05-11, version 10.7.0* Why is it a subscription? ### 1/5 — Almost *2026-04-16, version 10.7.0* One star because pipe trades pro demanded a review ### 1/5 — Glitching out *2025-06-24, version 10.5.7* This used to be a great app until it started glitching out. I’ve deleted it and then re-downloaded it and I still have a problem. ### 1/5 — Subscription *2025-05-10, version 10.5.7* This app is a one time purchase on Android but you have to pay monthly on Apple Ill buy it once but a subscription get outta here ### 1/5 — Monthly subscription *2025-04-03, version 10.5.7* Cool concept and nice to have on the phone but I’m not going to pay a monthly subscription ### 1/5 — Paywall *2025-03-20, version 10.5.7* Free to download, but hits you with an immediate paywall to use. ### 1/5 — Calculator *2024-10-29, version 10.5.2* It’s just a calculator, I could have used my normal calculator instead of paying free trial. I was looking for something to measure plumbing plans, this is not it. I’ll keep looking. ### 1/5 — Used to be a one time charge *2024-08-21, version 10.5.2* Used to be a one time charge and now they are greedy and need money monthly. Just buy the physical calculator and be done with it. ## Most praised reviews (10 highest-rated) ### 5/5 — Lovely Cals *2026-05-23* Using from 15 year my second calculator , up to now never failed me in any fabrication calculation 😍 **Developer response:** Thank you for the awesome review!

I think I paid 50 for this at the time. I don’t remember but if you are a pipe fitter or a plumber, this calculator is the one to get. ### 5/5 — Thank you PTP *2025-06-15, version 10.5.7* I’ve tried a few calculators but this is the go to one an definitely the best ### 5/5 — Superb Math App *2025-05-23, version 10.5.7* It's so Useful & so Handy!!! Before Cell Phones, I was using a PTP handheld calculator, and it was an excellent tool then, but so often, it was in my toolbox instead of with me. Now that it's on my iPhone, it's always with me!!! ### 5/5 — Keeps Getting Better *2025-02-23, version 10.5.7* I had one of the first iteration Pipe Trades Pro almost 20 years ago and still have my father’s. The app is great and it keeps getting better with added functionality. The help function and links to YouTube are super helpful. I would say it needs iPadOS functionality to be able to use iPad Pro’s split screen for layout. ### 5/5 — Inspection *2025-02-22, version 10.5.7* Always with you ### 5/5 — Pro Calc *2025-02-09, version 10.5.7* Favorite calculator --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
