The RedX Stairs - 3D Calculator extension empowers builders, designers, and DIY enthusiasts with advanced 3D visualization and precise stair calculation tools. It supports a broad range of stair types including Straight, L-Shaped, U-Shaped, Spiral, Winder, and Corner Deck Stairs.

Beyond calculation, it offers practical project management features—designs can be saved, shared, printed, or stored in-app. Specialized calculators for complex stair designs such as spiral and curved stairs with customizable rotation and radius parameters ensure precise execution.

User Reviews

Users largely praise RedX Stairs for ease of use and strong capabilities with complex stairs and comprehensive dimensions, with value even in the free version. However, recurring complaints focus on price and paywall, reliability issues (crashes and broken save), and input limitations (no cm/mm support or easy min/max entry) plus confusing trial cancellation. Overall, the app is seen as powerful but often hindered by cost and stability concerns.

Pros

Easy to use / user-friendly interface
Strong support for non-standard or complex stairs with complete dimensions
Useful even in the free version
Saves time by handling many necessary dimensions

Cons

Paywall: heavy reliance on paid subscription; free version is limited; high price
Stability issues: crashes and save feature not working
Input limitations and lack of guidance: cannot input certain values (min/max), no cm/mm support
Cancellation/trial friction: confusing process for cancelling the free trial
