User reviews

Locked behind paywall

If your gonna make it free make it free to use or charge to buy the app
And don’t put it behind a paywall after you download it
Its a Disappointment

Response from developer

Fair feedback. Every tool is free for 7 days with no payment up front, but we hear you that a permanently free tier matters, and we're working on exactly that.

Doesn’t work without a subscription

I have Construction Master Pro and was trying to switch to a more intuitive calculator, and get rid of the subscription, and it turns out you can’t calculate anything on here either unless you subscribe. Sure there’s a free trial but it’s really pushing the “subscribe” button. I’m sorry I couldn’t try out the calculators that this has.

Response from developer

Thank you for the feedback. We're in the process of making a totally free tier that we hope you'll try in the future. We understand asking people to subscribe (even if the first week is free), isn't the greatest user experience.
