I own this app, have purchased for my iPad, I have recommended it to every architect, engineer, and subcontractor I know, and yesterday when purchasing for my sister we found out there’s a subscription… sadly, I cannot recommend a subscription app when Home Depot sells them for $40-$50… I wouldn’t mind if you were to increase the price for such useful app, but a subscription really is killing it for me… I hope you are able to bring back this app…
Requires a heft yearly subscription for a calculator. This is corporate greed at its finest.
I owe this on android, but I Just switched to iOS. It is really unfortunate that your company is not letting us buy it out right. I’m a little disappointed and will not be paying a subscription
I like everything except I don’t know how to erase ONLY the last digit put in by mistake,so you have to delete and start all over. My old stand alone model had a backspace arrow,so you don’t lose all of your calculations. That’s all. Somebody’s gonna let me know how to do it. I just know it. I hope so!!
Stop resetting my settings every time I open the app. The clicks are terrible
i’ve paid $25 for each of my employees to have this app on their phone. Now, you want $40/yr??? for what? we are scrambling to ensure no one updates to this subscription version. What an incredibly horrible way to treat customers that have supported you all these years!!!
The new logo is trash 🤮
I have had this on my iPhone for a very long time. Super convenient because you normally always have your phone on hand, not always a calculator when you need one in the field or shop. I have used this as a metal fabricator, structural fitter, ironworking in buildings, plants and working on large ships. This app is always updated with newer software which you cannot do with a calculator. If you use a calculator in the trades, just get this app.
Use it all the time. Thanks for making a great tool.
Best calculator ever
