User Reviews

User feedback is mixed. Some praise the app for its ease of use and long-term usefulness, especially for rise/run and stringer calculations with multiple outputs. However, recurring complaints focus on billing/cancellation issues, intrusive ads, and perceived low value or trust concerns. A portion of users also find it not helpful for specific projects. Overall, the app is easy to use, but billing practices and ad-heavy behavior affect reliability for many users.

Pros

Very easy to use.
Has proven useful over many years for takeoffs and stair calculations.
Supports rise/run and stringer calculations with multiple output options and quick scenario analysis.

Cons

Difficult to cancel subscriptions/free trials within the app; reports of no cancellation option and poor responsiveness from developers.
Ads are intrusive and disruptive to workflow, with obnoxious frequency of ads.
Some reviews claim the app is a scam or fails to deliver promised information/diagrams, leading to poor perceived value.
Not all features meet real-world needs; several users find it confusing or not helpful for certain remodeling scenarios.
