What is Piping Pipit?
Piping Pipit is an app that lets you quickly calculate cut lengths from combinations of fittings.
What you can do with Piping Pipit
Cut length calculation
→ Calculate cut lengths based on fitting combinations
Check dimension drawings
→ View pipe and fitting shapes and dimensions in a 3D pipe catalog
Currently supported fittings
DV fittings (PVC drainage pipes)
TS/HI fittings (PVC water supply pipes)
HT fittings (PVC supply pipes)
White-thread fittings (Threaded malleable iron pipe fittings)
Water Supply Core Fittings (Threaded Anti-Corrosion Pipe-End Fittings for Lined Steel Pipes)
Butt-weld fittings
Stainless Press-Type Fittings.
Additional fittings will be supported in future updates.
Features such as sharing containers and measurement results with others, as well as quantity estimation, are also planned. Stay tuned!

more When a DV 90° elbow or 90° Y fitting is connected, you can now view the hypotenuse length and vertical offset caused by the fitting's actual 91.17° angle from the cut-length screen.
1.6.1 10 Sept
Version 1.6.0
• Fixed an issue where the branch diameter of a reducing 45° Y fitting could not be selected correctly in 45° mode.
• Added a lifetime purchase option for Pro.
• Added an ad-supported plan.
• Fixed an issue where history might not be saved or displayed.
Version 1.5.5
• Added copper pipes and copper fittings.
• Added a material quantity takeoff feature.
Register materials and quantities, then review and adjust the takeoff results in a list.
Voice input is also supported for material takeoff. This is currently an experimental implementation, so recognition accuracy and other aspects are limited.
Takeoff data can be exported to and imported from files, making it useful for sharing with other users and for backups.
CSV and Excel export are supported.
• Added Real Mode.
Highlights and shadows are displayed on 3D models, making the shapes of pipes and fittings easier to view in three dimensions.
Version 1.5.3
• Improved the Pro purchase screen, making monthly and annual plan details and subscription status easier to review.
• Improved reliability when reflecting Pro purchase status and restored purchases in the app.
• Improved stability.
