Button *2025-10-29, version 12.8.7* Overall love your calculators and have used them for ~30 years, thank you. I would like to know what happened to the S.F. button? Please bring it back.

Cause I purchased lifetime app. Now it’s yearly. *2025-08-25, version 12.8.7* Not able to download to iPhone was able to download to iPad. I purchased lifetime app 10 years ago now it’s a yearly app. Ripoff ### 1/5 — App used to be a fixed fee *2024-06-03, version 12.4.13* This app used to cost a single flat fee purchase cost, and now has been overtaken by greed. Paying a yearly subscription for a calculator for 4x the cost the exact same app used to be for sale for almost a decade ago tells you everything you need to know about this app. Don’t waste your time buying this, there are much better alternatives in the App Store that don’t see you as a human piggy bank. ### 1/5 — Not so good…. *2024-03-13, version 12.4.13* The only reason I downloaded this was for my later job and when I got it it didn’t let me get off of the free trial screen so this is why I gave this 1 star. ### 1/5 — No *2023-03-14, version 12.0.7* No ### 1/5 — Free to download, cost to use. *2022-05-20, version 11.4.8* Says it’s a free app but can’t use unless you pay for a subscription ### 1/5 — App not sizing properly! *2021-12-23* On 13 pro max, app only rendering in 1/4th of the screen! Please fix! **Developer response:** Thank you for reaching out, can you uninstall and reinstall and try again? ### 1/5 — Missing things *2018-10-23, version 1.3.0* A construction calculator that has no diagonal and stair function is a waste of money... don’t bother ### 1/5 — Needs help *2017-08-15, version 1.2.0* This needs an update that gets me rise, run, and diagonal. I use that more than anything else. I feel like I completely wasted my money. Please update and improve. ### 1/5 — Construction calculator *2017-03-20, version 1.2.0* Spent $10 on this app only to find out there's no rise/ run /pitch function in it; making it effectively useless to most carpenters or anyone needing to find an arbitrary square line. ### 2/5 — Used to be good *2021-02-19, version 10.5.0* I bought this app as it’s one of the top three most useful things for drafting, engineering, field work. It used to just work, now, everyone I launch it i have to click through an ad. What the heck happened to just using things you paid for? Please clean up the weeds out of your walled garden apple. Besides the ads, app is still very useful btw. ## Most praised reviews (10 highest-rated) ### 5/5 — Very useful *2026-08-07, version 12.10.17* .

I have been using it for 10+ years and it is perfect! It does everything I need it to do in the construction industry ### 5/5 — Best app *2025-12-08, version 12.8.7* I have been using math conversion apps for a long time and I settled on this years ago and then I went to an android and I couldn’t convert my account over to my android and so I just may do and forgot about it and then I got another Apple phone and I went and re-downloaded it. It still had my information so I did not have to re-purchase it and it just by far is the best way to go when you’re trying to convert and do angles and degrees and fractions or anything volumes anything it’s really good. ### 5/5 — Super *2025-12-07, version 12.8.7* This is really great.
